+## v1.0 beta 1 [2016-06-07]
+
+### Release Notes
+
+- `flush_jitter` behavior has been changed. The random jitter will now be
+evaluated at every flush interval, rather than once at startup. This makes it
+consistent with the behavior of `collection_jitter`.
+
+- All AWS plugins now utilize a standard mechanism for evaluating credentials.
+This allows all AWS plugins to support environment variables, shared credential
+files & profiles, and role assumptions. See the specific plugin README for
+details.
+
+- The AWS CloudWatch input plugin can now declare a wildcard value for a metric
+dimension. This causes the plugin to read all metrics that contain the specified
+dimension key regardless of value. This is used to export collections of metrics
+without having to know the dimension values ahead of time.
+
+- The AWS CloudWatch input plugin can now be configured with the `cache_ttl`
+attribute. This configures the TTL of the internal metric cache. This is useful
+in conjunction with wildcard dimension values as it will control the amount of
+time before a new metric is included by the plugin.
+

+
+## v0.13 [2016-05-11]
+
+### Release Notes
+
+- **Breaking change** in jolokia plugin. See
+https://github.com/influxdata/telegraf/blob/master/plugins/inputs/jolokia/README.md
+for updated configuration. The plugin will now support proxy mode and will make
+POST requests.
+
+- New [agent] configuration option: `metric_batch_size`. This option tells
+telegraf the maximum batch size to allow to accumulate before sending a flush
+to the configured outputs. `metric_buffer_limit` now refers to the absolute
+maximum number of metrics that will accumulate before metrics are dropped.
+
+- There is no longer an option to
+`flush_buffer_when_full`, this is now the default and only behavior of telegraf.
+
+- **Breaking Change**: docker plugin tags. The cont_id tag no longer exists, it
+will now be a field, and be called container_id. Additionally, cont_image and
+cont_name are being renamed to container_image and container_name.
+
+- **Breaking Change**: docker plugin measurements. The `docker_cpu`, `docker_mem`,
+`docker_blkio` and `docker_net` measurements are being renamed to
+`docker_container_cpu`, `docker_container_mem`, `docker_container_blkio` and
+`docker_container_net`. Why? Because these metrics are
+specifically tracking per-container stats. The problem with per-container stats,
+in some use-cases, is that if containers are short-lived AND names are not
+kept consistent, then the series cardinality will balloon very quickly.
+So adding "container" to each metric will:
+(1) make it more clear that these metrics are per-container, and
+(2) allow users to easily drop per-container metrics if cardinality is an
+issue (`namedrop = ["docker_container_*"]`)
+
+- `tagexclude` and `taginclude` are now available, which can be used to remove
+tags from measurements on inputs and outputs. See
+[the configuration doc](https://github.com/influxdata/telegraf/blob/master/docs/CONFIGURATION.md)
+for more details.
+
+- **Measurement filtering:** All measurement filters now match based on glob
+only. Previously there was an undocumented behavior where filters would match
+based on _prefix_ in addition to globs. This means that a filter like
+`fielddrop = ["time_"]` will need to be changed to `fielddrop = ["time_*"]`
+
+- **datadog**: measurement and field names will no longer have `_` replaced by `.`
+
+- The following plugins have changed their tags to _not_ overwrite the host tag:
+  - cassandra: `host -> cassandra_host`
+  - disque: `host -> disque_host`
+  - rethinkdb: `host -> rethinkdb_host`
+
+- **Breaking Change**: The `win_perf_counters` input has been changed to
+sanitize field names, replacing `/Sec` and `/sec` with `_persec`, as well as
+spaces with underscores. This is needed because Graphite doesn't like slashes
+and spaces, and was failing to accept metrics that had them.
+The `/[sS]ec` -> `_persec` is just to make things clearer and uniform.
+
+- **Breaking Change**: snmp plugin. The `host` tag of the snmp plugin has been
+changed to the `snmp_host` tag.
+
+- The `disk` input plugin can now be configured with the `HOST_MOUNT_PREFIX` environment variable.
+This value is prepended to any mountpaths discovered before retrieving stats.
+It is not included on the report path. This is necessary for reporting host disk stats when running from within a container.
+

+## v0.10.3 [2016-02-18]
+
+### Release Notes
+- Users of the `exec` and `kafka_consumer` (and the new `nats_consumer`
+and `mqtt_consumer` plugins) can now specify the incoming data
+format that they would like to parse. Currently supports: "json", "influx", and
+"graphite"
+- Users of message broker and file output plugins can now choose what data format
+they would like to output. Currently supports: "influx" and "graphite"
+- More info on parsing _incoming_ data formats can be found
+[here](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md)

+[here](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md)
+- Telegraf now has an option `flush_buffer_when_full` that will flush the
+metric buffer whenever it fills up for each output, rather than dropping
+points and only flushing on a set time interval. This will default to `true`
+and is in the `[agent]` config section.

+fields.
+- Graphite output now inserts tags into the bucket in alphabetical order.
+- Normalized TLS/SSL support for output plugins: MQTT, AMQP, Kafka

+
+## v0.10.1 [2016-01-27]
+
+### Release Notes
+
+- Telegraf now keeps a fixed-length buffer of metrics per-output. This buffer
+defaults to 10,000 metrics, and is adjustable. The buffer is cleared when a
+successful write to that output occurs.
+- The docker plugin has been significantly overhauled to add more metrics
+and allow for docker-machine (incl OSX) support.
+[See the readme](https://github.com/influxdata/telegraf/blob/master/plugins/inputs/docker/README.md)
+for the latest measurements, fields, and tags. There is also now support for
+specifying a docker endpoint to get metrics from.

+
+## v0.10.0 [2016-01-12]
+
+### Release Notes
+- Linux packages have been taken out of `opt`, the binary is now in `/usr/bin`
+and configuration files are in `/etc/telegraf`
+- **breaking change** `plugins` have been renamed to `inputs`. This was done because
+`plugins` is too generic, as there are now also "output plugins", and will likely
+be "aggregator plugins" and "filter plugins" in the future. Additionally,
+`inputs/` and `outputs/` directories have been placed in the root-level `plugins/`
+directory.
+- **breaking change** the `io` plugin has been renamed `diskio`
+- **breaking change** plugin measurements aggregated into a single measurement.
+- **breaking change** `jolokia` plugin: must use global tag/drop/pass parameters
+for configuration.
+- **breaking change** `twemproxy` plugin: `prefix` option removed.
+- **breaking change** `procstat` cpu measurements are now prepended with `cpu_time_`
+instead of only `cpu_`
+- **breaking change** some command-line flags have been renamed to separate words.
+`-configdirectory` -> `-config-directory`, `-filter` -> `-input-filter`,
+`-outputfilter` -> `-output-filter`
+- The prometheus plugin schema has not been changed (measurements have not been
+aggregated).
+
+### Packaging change note:
+
+RHEL/CentOS users upgrading from 0.2.x to 0.10.0 will probably have their
+configurations overwritten by the upgrade. There is a backup stored at
+/etc/telegraf/telegraf.conf.$(date +%s).backup.
+
+### Features
+- Plugin measurements aggregated into a single measurement.
+- Added ability to specify per-plugin tags
+- Added ability to specify per-plugin measurement suffix and prefix.
+(`name_prefix` and `name_suffix`)
+- Added ability to override base plugin measurement name. (`name_override`)
+

+
+## v0.2.3 [2015-11-30]
+
+### Release Notes
+- **breaking change** The `kafka` plugin has been renamed to `kafka_consumer`.
+and most of the config option names have changed.
+This only affects the kafka consumer _plugin_ (not the
+output). There were a number of problems with the kafka plugin that led to it
+only collecting data once at startup, so the kafka plugin was basically non-
+functional.
+- Plugins can now be specified as a list, and multiple plugin instances of the
+same type can be specified, like this:
+
+```
+[[inputs.cpu]]
+  percpu = false
+  totalcpu = true
+
+[[inputs.cpu]]
+  percpu = true
+  totalcpu = false
+  drop = ["cpu_time"]
+```
+
+- Riemann output added

+
+## v0.2.2 [2015-11-18]
+
+### Release Notes
+- 0.2.1 has a bug where all lists within plugins get duplicated, this includes
+lists of servers/URLs. 0.2.2 is being released solely to fix that bug
+
+### Bugfixes
+- [#377](https://github.com/influxdata/telegraf/pull/377): Fix for duplicate slices in inputs.
+
+## v0.2.1 [2015-11-16]
+
+### Release Notes
+- Telegraf will no longer use docker-compose for "long" unit test, it has been
+changed to just run docker commands in the Makefile. See `make docker-run` and
+`make docker-kill`. `make test` will still run all unit tests with docker.
+- Long unit tests are now run in CircleCI, with docker & race detector
+- Redis plugin tag has changed from `host` to `server`
+- HAProxy plugin tag has changed from `host` to `server`
+- UDP output now supported
+- Telegraf will now compile on FreeBSD
+- Users can now specify outputs as lists, specifying multiple outputs of the
+same type.

+- [#360](https://github.com/influxdata/telegraf/pull/360): Apply prefix before ShouldPass check. Thanks @sotfo!
+
+## v0.2.0 [2015-10-27]
+
+### Release Notes
+- The -test flag will now only output 2 collections for plugins that need it
+- There is a new agent configuration option: `flush_interval`. This option tells
+Telegraf how often to flush data to InfluxDB and other output sinks. For example,
+users can set `interval = "2s"` and `flush_interval = "60s"` for Telegraf to
+collect data every 2 seconds, and flush every 60 seconds.
+- `precision` and `utc` are no longer valid agent config values. `precision` has
+moved to the `influxdb` output config, where it will continue to default to "s"
+- debug and test output will now print the raw line-protocol string
+- Telegraf will now, by default, round the collection interval to the nearest
+even interval. This means that `interval="10s"` will collect every :00, :10, etc.
+To ease scale concerns, flushing will be "jittered" by a random amount so that
+all Telegraf instances do not flush at the same time. Both of these options can
+be controlled via the `round_interval` and `flush_jitter` config options.
+- Telegraf will now retry metric flushes twice
+

+allow filtering of output sinks on the command-line using the `-outputfilter`
+flag, much like how the `-filter` flag works for inputs.
+- Support for filtering on config-file creation -- Telegraf now supports
+filtering to -sample-config command. You can now run
+`telegraf -sample-config -filter cpu -outputfilter influxdb` to get a config
+file with only the cpu plugin defined, and the influxdb output defined.
+- **Breaking Change**: The CPU collection plugin has been refactored to fix some
+bugs and outdated dependency issues. At the same time, I also decided to fix
+a naming consistency issue, so cpu_percentageIdle will become cpu_usage_idle.
+Also, all CPU time measurements now have it indicated in their name, so cpu_idle
+will become cpu_time_idle. Additionally, cpu_time measurements are going to be
+dropped in the default config.
+- **Breaking Change**: The memory plugin has been refactored and some measurements
+have been renamed for consistency. Some measurements have also been removed from being outputted. They are still being collected by gopsutil, and could easily be
+re-added in a "verbose" mode if there is demand for it.

+## Steps for Contributing:
+
+1. [Sign the CLA](http://influxdb.com/community/cla.html)
+1. Make changes or write plugin (see below for details)
+1. Add your plugin to `plugins/inputs/all/all.go` or `plugins/outputs/all/all.go`
+1. If your plugin requires a new Go package,
+[add it](https://github.com/influxdata/telegraf/blob/master/CONTRIBUTING.md#adding-a-dependency)
+1. Write a README for your plugin, if it's an input plugin, it should be structured
+like the [input example here](https://github.com/influxdata/telegraf/blob/master/plugins/inputs/EXAMPLE_README.md).
+Output plugins READMEs are less structured,
+but any information you can provide on how the data will look is appreciated.
+See the [OpenTSDB output](https://github.com/influxdata/telegraf/tree/master/plugins/outputs/opentsdb)
+for a good example.
+
+## GoDoc
+
+Public interfaces for inputs, outputs, metrics, and the accumulator can be found
+on the GoDoc
+
+[![GoDoc](https://godoc.org/github.com/influxdata/telegraf?status.svg)](https://godoc.org/github.com/influxdata/telegraf)
+
+## Sign the CLA
+
+Before we can merge a pull request, you will need to sign the CLA,
+which can be found [on our website](http://influxdb.com/community/cla.html)
+
+## Adding a dependency
+
+Assuming you can already build the project, run these in the telegraf directory:
+
+1. `go get github.com/sparrc/gdm`
+1. `gdm restore`
+1. `gdm save`
+
+## Input Plugins
+
+This section is for developers who want to create new collection inputs.
+Telegraf is entirely plugin driven. This interface allows for operators to
+pick and chose what is gathered and makes it easy for developers
+to create new ways of generating metrics.
+
+Plugin authorship is kept as simple as possible to promote people to develop
+and submit new inputs.
+
+### Input Plugin Guidelines
+
+* A plugin must conform to the `telegraf.Input` interface.
+* Input Plugins should call `inputs.Add` in their `init` function to register themselves.
+See below for a quick example.
+* Input Plugins must be added to the
+`github.com/influxdata/telegraf/plugins/inputs/all/all.go` file.
+* The `SampleConfig` function should return valid toml that describes how the
+plugin can be configured. This is include in `telegraf -sample-config`.
+* The `Description` function should say in one line what this plugin does.
+
+Let's say you've written a plugin that emits metrics about processes on the
+current host.
+
+### Input Plugin Example
+
+```go
+package simple
+
+// simple.go
+
+import (
+    "github.com/influxdata/telegraf"
+    "github.com/influxdata/telegraf/plugins/inputs"
+)
+
+type Simple struct {
+    Ok bool
+}
+
+func (s *Simple) Description() string {
+    return "a demo plugin"
+}
+
+func (s *Simple) SampleConfig() string {
+    return "ok = true # indicate if everything is fine"
+}
+
+func (s *Simple) Gather(acc telegraf.Accumulator) error {
+    if s.Ok {
+        acc.Add("state", "pretty good", nil)
+    } else {
+        acc.Add("state", "not great", nil)
+    }
+
+    return nil
+}
+
+func init() {
+    inputs.Add("simple", func() telegraf.Input { return &Simple{} })
+}
+```
+
+## Input Plugins Accepting Arbitrary Data Formats
+
+Some input plugins (such as
+[exec](https://github.com/influxdata/telegraf/tree/master/plugins/inputs/exec))
+accept arbitrary input data formats. An overview of these data formats can
+be found
+[here](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md).
+
+In order to enable this, you must specify a `SetParser(parser parsers.Parser)`
+function on the plugin object (see the exec plugin for an example), as well as
+defining `parser` as a field of the object.
+
+You can then utilize the parser internally in your plugin, parsing data as you
+see fit. Telegraf's configuration layer will take care of instantiating and
+creating the `Parser` object.
+
+You should also add the following to your SampleConfig() return:
+
+```toml
+  ## Data format to consume. 
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
+  data_format = "influx"
+```
+
+Below is the `Parser` interface.
+
+```go
+// Parser is an interface defining functions that a parser plugin must satisfy.
+type Parser interface {
+    // Parse takes a byte buffer separated by newlines
+    // ie, `cpu.usage.idle 90\ncpu.usage.busy 10`
+    // and parses it into telegraf metrics
+    Parse(buf []byte) ([]telegraf.Metric, error)
+
+    // ParseLine takes a single string metric
+    // ie, "cpu.usage.idle 90"
+    // and parses it into a telegraf metric.
+    ParseLine(line string) (telegraf.Metric, error)
+}
+```
+
+And you can view the code
+[here.](https://github.com/influxdata/telegraf/blob/henrypfhu-master/plugins/parsers/registry.go)
+
+## Service Input Plugins
+
+This section is for developers who want to create new "service" collection
+inputs. A service plugin differs from a regular plugin in that it operates
+a background service while Telegraf is running. One example would be the `statsd`
+plugin, which operates a statsd server.
+
+Service Input Plugins are substantially more complicated than a regular plugin, as they
+will require threads and locks to verify data integrity. Service Input Plugins should
+be avoided unless there is no way to create their behavior with a regular plugin.
+
+Their interface is quite similar to a regular plugin, with the addition of `Start()`
+and `Stop()` methods.
+
+### Service Plugin Guidelines
+
+* Same as the `Plugin` guidelines, except that they must conform to the
+`inputs.ServiceInput` interface.
+
+## Output Plugins
+
+This section is for developers who want to create a new output sink. Outputs
+are created in a similar manner as collection plugins, and their interface has
+similar constructs.
+
+### Output Plugin Guidelines
+
+* An output must conform to the `outputs.Output` interface.
+* Outputs should call `outputs.Add` in their `init` function to register themselves.
+See below for a quick example.
+* To be available within Telegraf itself, plugins must add themselves to the
+`github.com/influxdata/telegraf/plugins/outputs/all/all.go` file.
+* The `SampleConfig` function should return valid toml that describes how the
+output can be configured. This is include in `telegraf -sample-config`.
+* The `Description` function should say in one line what this output does.
+
+### Output Example
+
+```go
+package simpleoutput
+
+// simpleoutput.go
+
+import (
+    "github.com/influxdata/telegraf"
+    "github.com/influxdata/telegraf/plugins/outputs"
+)
+
+type Simple struct {
+    Ok bool
+}
+
+func (s *Simple) Description() string {
+    return "a demo output"
+}
+
+func (s *Simple) SampleConfig() string {
+    return "url = localhost"
+}
+
+func (s *Simple) Connect() error {
+    // Make a connection to the URL here
+    return nil
+}
+
+func (s *Simple) Close() error {
+    // Close connection to the URL here
+    return nil
+}
+
+func (s *Simple) Write(metrics []telegraf.Metric) error {
+    for _, metric := range metrics {
+        // write `metric` to the output sink here
+    }
+    return nil
+}
+
+func init() {
+    outputs.Add("simpleoutput", func() telegraf.Output { return &Simple{} })
+}
+
+```
+
+## Output Plugins Writing Arbitrary Data Formats
+
+Some output plugins (such as
+[file](https://github.com/influxdata/telegraf/tree/master/plugins/outputs/file))
+can write arbitrary output data formats. An overview of these data formats can
+be found
+[here](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md).
+
+In order to enable this, you must specify a
+`SetSerializer(serializer serializers.Serializer)`
+function on the plugin object (see the file plugin for an example), as well as
+defining `serializer` as a field of the object.
+
+You can then utilize the serializer internally in your plugin, serializing data
+before it's written. Telegraf's configuration layer will take care of
+instantiating and creating the `Serializer` object.
+
+You should also add the following to your SampleConfig() return:
+
+```toml
+  ## Data format to output. 
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md
+  data_format = "influx"
+```
+
+## Service Output Plugins
+
+This section is for developers who want to create new "service" output. A
+service output differs from a regular output in that it operates a background service
+while Telegraf is running. One example would be the `prometheus_client` output,
+which operates an HTTP server.
+
+Their interface is quite similar to a regular output, with the addition of `Start()`
+and `Stop()` methods.
+
+### Service Output Guidelines
+
+* Same as the `Output` guidelines, except that they must conform to the
+`output.ServiceOutput` interface.
+
+## Unit Tests
+
+### Execute short tests
+
+execute `make test-short`
+
+### Execute long tests
+
+As Telegraf collects metrics from several third-party services it becomes a
+difficult task to mock each service as some of them have complicated protocols
+which would take some time to replicate.
+
+To overcome this situation we've decided to use docker containers to provide a
+fast and reproducible environment to test those services which require it.
+For other situations
+(i.e: https://github.com/influxdata/telegraf/blob/master/plugins/inputs/redis/redis_test.go)
+a simple mock will suffice.
+
+To execute Telegraf tests follow these simple steps:
+
+- Install docker following [these](https://docs.docker.com/installation/)
+instructions
+- execute `make test`
+
+**OSX users**: you will need to install `boot2docker` or `docker-machine`.
+The Makefile will assume that you have a `docker-machine` box called `default` to
+get the IP address.
+
+### Unit test troubleshooting
+
+Try cleaning up your test environment by executing `make docker-kill` and
+re-running

+### From Source:

-## Telegraf Options
+Telegraf manages dependencies via [gdm](https://github.com/sparrc/gdm),
+which gets installed via the Makefile
+if you don't have it already. You also must build with golang version 1.5+.

-Telegraf has a few options you can configure under the `agent` section of the config. If you don't see an `agent` section run `telegraf -sample-config > telegraf.toml` to create a valid initial configuration:
+1. [Install Go](https://golang.org/doc/install)
+2. [Setup your GOPATH](https://golang.org/doc/code.html#GOPATH)
+3. Run `go get github.com/influxdata/telegraf`
+4. Run `cd $GOPATH/src/github.com/influxdata/telegraf`
+5. Run `make`

-* **hostname**: The hostname is passed as a tag. By default this will be the value retured by `hostname` on the machine running Telegraf. You can override that value here.
-* **interval**: How ofter to gather metrics. Uses a simple number + unit parser, ie "10s" for 10 seconds or "5m" for 5 minutes.
-* **debug**: Set to true to gather and send metrics to STDOUT as well as InfluxDB.
+## How to use it:

-## Supported Plugins
+```console
+$ telegraf -help
+Telegraf, The plugin-driven server agent for collecting and reporting metrics.

-Telegraf currently has support for collecting metrics from:
+Usage:

-* System (memory, CPU, network, etc.)
-* Docker
-* MySQL
-* Prometheus (client libraries and exporters)
-* PostgreSQL
-* Redis
+  telegraf <flags>

-We'll be adding support for many more over the coming months. Read on if you want to add support for another service or third-party API.
+The flags are:

-## Plugin Options
+  -config <file>     configuration file to load
+  -test              gather metrics once, print them to stdout, and exit
+  -sample-config     print out full sample configuration to stdout
+  -config-directory  directory containing additional *.conf files
+  -input-filter      filter the input plugins to enable, separator is :
+  -output-filter     filter the output plugins to enable, separator is :
+  -usage             print usage for a plugin, ie, 'telegraf -usage mysql'
+  -debug             print metrics as they're generated to stdout
+  -quiet             run in quiet mode
+  -version           print the version to stdout

-There are 3 configuration options that are configurable per plugin:
+Examples:

-* **pass**: An array of strings that is used to filter metrics generated by the current plugin. Each string in the array is tested as a prefix against metrics and if it matches, the metric is emitted.
-* **drop**: The inverse of pass, if a metric matches, it is not emitted.
-* **interval**: How often to gather this metric. Normal plugins use a single global interval, but if one particular plugin should be run less or more often, you can configure that here.
+  # generate a telegraf config file:
+  telegraf -sample-config > telegraf.conf

-## Plugins
+  # generate config with only cpu input & influxdb output plugins defined
+  telegraf -sample-config -input-filter cpu -output-filter influxdb

-This section is for developers that want to create new collection plugins. Telegraf is entirely plugin driven. This interface allows for operators to
-pick and chose what is gathered as well as makes it easy for developers
-to create new ways of generating metrics.
+  # run a single telegraf collection, outputing metrics to stdout
+  telegraf -config telegraf.conf -test

-Plugin authorship is kept as simple as possible to promote people to develop
-and submit new plugins.
+  # run telegraf with all plugins defined in config file
+  telegraf -config telegraf.conf

-## Guidelines
-
-* A plugin must conform to the `plugins.Plugin` interface.
-* Telegraf promises to run each plugin's Gather function serially. This means
-developers don't have to worry about thread safety within these functions.
-* Each generated metric automatically has the name of the plugin that generated
-it prepended. This is to keep plugins honest.
-* Plugins should call `plugins.Add` in their `init` function to register themselves.
-See below for a quick example.
-* To be available within Telegraf itself, plugins must add themselves to the `github.com/influxdb/telegraf/plugins/all/all.go` file.
-* The `SampleConfig` function should return valid toml that describes how the plugin can be configured. This is include in `telegraf -sample-config`.
-* The `Description` function should say in one line what this plugin does.
-
-### Plugin interface
-
-```go
-type Plugin interface {
-  SampleConfig() string
-  Description() string
-  Gather(Accumulator) error
-}
-
-type Accumulator interface {
-  Add(measurement string, value interface{}, tags map[string]string)
-  AddValuesWithTime(measurement string, values map[string]interface{}, tags map[string]string, timestamp time.Time)
-}
+  # run telegraf, enabling the cpu & memory input, and influxdb output plugins
+  telegraf -config telegraf.conf -input-filter cpu:mem -output-filter influxdb
 ```

-### Accumulator
+## Configuration

-The way that a plugin emits metrics is by interacting with the Accumulator.
+See the [configuration guide](docs/CONFIGURATION.md) for a rundown of the more advanced
+configuration options.

-The `Add` function takes 3 arguments:
-* **measurement**: A string description of the metric. For instance `bytes_read` or `faults`.
-* **value**: A value for the metric. This accepts 5 different types of value:
-  * **int**: The most common type. All int types are accepted but favor using `int64`
-  Useful for counters, etc.
-  * **float**: Favor `float64`, useful for gauges, percentages, etc.
-  * **bool**: `true` or `false`, useful to indicate the presence of a state. `light_on`, etc.
-  * **string**: Typically used to indicate a message, or some kind of freeform information.
-  * **time.Time**: Useful for indicating when a state last occurred, for instance `light_on_since`.
-* **tags**: This is a map of strings to strings to describe the where or who about the metric. For instance, the `net` plugin adds a tag named `"interface"` set to the name of the network interface, like `"eth0"`.
+## Supported Input Plugins

-The `AddValuesWithTime` allows multiple values for a point to be passed. The values
-used are the same type profile as **value** above. The **timestamp** argument
-allows a point to be registered as having occurred at an arbitrary time.
+Telegraf currently has support for collecting metrics from many sources. For
+more information on each, please look at the directory of the same name in
+`plugins/inputs`.

-Let's say you've written a plugin that emits metrics about processes on the current host.

+Usage:
+
+  telegraf <flags>
+
+The flags are:
+
+  -config <file>     configuration file to load
+  -test              gather metrics once, print them to stdout, and exit
+  -sample-config     print out full sample configuration to stdout
+  -config-directory  directory containing additional *.conf files
+  -input-filter      filter the input plugins to enable, separator is :
+  -input-list        print all the plugins inputs
+  -output-filter     filter the output plugins to enable, separator is :
+  -output-list       print all the available outputs
+  -usage             print usage for a plugin, ie, 'telegraf -usage mysql'
+  -debug             print metrics as they're generated to stdout
+  -quiet             run in quiet mode
+  -version           print the version to stdout
+
+In addition to the -config flag, telegraf will also load the config file from
+an environment variable or default location. Precedence is:
+  1. -config flag
+  2. $TELEGRAF_CONFIG_PATH environment variable
+  3. $HOME/.telegraf/telegraf.conf
+  4. /etc/telegraf/telegraf.conf
+
+Examples:
+
+  # generate a telegraf config file:
+  telegraf -sample-config > telegraf.conf
+
+  # generate config with only cpu input & influxdb output plugins defined
+  telegraf -sample-config -input-filter cpu -output-filter influxdb
+
+  # run a single telegraf collection, outputing metrics to stdout
+  telegraf -config telegraf.conf -test
+
+  # run telegraf with all plugins defined in config file
+  telegraf -config telegraf.conf

+# Telegraf Configuration
+
+## Generating a Configuration File
+
+A default Telegraf config file can be generated using the -sample-config flag:
+
+```
+telegraf -sample-config > telegraf.conf
+```
+
+To generate a file with specific inputs and outputs, you can use the
+-input-filter and -output-filter flags:
+
+```
+telegraf -sample-config -input-filter cpu:mem:net:swap -output-filter influxdb:kafka
+```
+
+You can see the latest config file with all available plugins here:
+[telegraf.conf](https://github.com/influxdata/telegraf/blob/master/etc/telegraf.conf)
+
+## Environment Variables
+
+Environment variables can be used anywhere in the config file, simply prepend
+them with $. For strings the variable must be within quotes (ie, "$STR_VAR"),
+for numbers and booleans they should be plain (ie, $INT_VAR, $BOOL_VAR)
+
+## `[global_tags]` Configuration
+
+Global tags can be specified in the `[global_tags]` section of the config file
+in key="value" format. All metrics being gathered on this host will be tagged
+with the tags specified here.
+
+## `[agent]` Configuration
+
+Telegraf has a few options you can configure under the `agent` section of the
+config.
+
+* **interval**: Default data collection interval for all inputs
+* **round_interval**: Rounds collection interval to 'interval'
+ie, if interval="10s" then always collect on :00, :10, :20, etc.
+* **metric_batch_size**: Telegraf will send metrics to output in batch of at
+most metric_batch_size metrics.
+* **metric_buffer_limit**: Telegraf will cache metric_buffer_limit metrics
+for each output, and will flush this buffer on a successful write.
+This should be a multiple of metric_batch_size and could not be less
+than 2 times metric_batch_size.
+* **collection_jitter**: Collection jitter is used to jitter
+the collection by a random amount.
+Each plugin will sleep for a random time within jitter before collecting.
+This can be used to avoid many plugins querying things like sysfs at the
+same time, which can have a measurable effect on the system.
+* **flush_interval**: Default data flushing interval for all outputs.
+You should not set this below
+interval. Maximum flush_interval will be flush_interval + flush_jitter
+* **flush_jitter**: Jitter the flush interval by a random amount.
+This is primarily to avoid
+large write spikes for users running a large number of telegraf instances.
+ie, a jitter of 5s and flush_interval 10s means flushes will happen every 10-15s.
+* **debug**: Run telegraf in debug mode.
+* **quiet**: Run telegraf in quiet mode.
+* **hostname**: Override default hostname, if empty use os.Hostname().
+
+#### Measurement Filtering
+
+Filters can be configured per input or output, see below for examples.
+
+* **namepass**: An array of strings that is used to filter metrics generated by the
+current input. Each string in the array is tested as a glob match against
+measurement names and if it matches, the field is emitted.
+* **namedrop**: The inverse of pass, if a measurement name matches, it is not emitted.
+* **fieldpass**: An array of strings that is used to filter metrics generated by the
+current input. Each string in the array is tested as a glob match against field names
+and if it matches, the field is emitted. fieldpass is not available for outputs.
+* **fielddrop**: The inverse of pass, if a field name matches, it is not emitted.
+fielddrop is not available for outputs.
+* **tagpass**: tag names and arrays of strings that are used to filter
+measurements by the current input. Each string in the array is tested as a glob
+match against the tag name, and if it matches the measurement is emitted.
+* **tagdrop**: The inverse of tagpass. If a tag matches, the measurement is not
+emitted. This is tested on measurements that have passed the tagpass test.
+* **tagexclude**: tagexclude can be used to exclude a tag from measurement(s).
+As opposed to tagdrop, which will drop an entire measurement based on it's
+tags, tagexclude simply strips the given tag keys from the measurement. This
+can be used on inputs & outputs, but it is _recommended_ to be used on inputs,
+as it is more efficient to filter out tags at the ingestion point.
+* **taginclude**: taginclude is the inverse of tagexclude. It will only include
+the tag keys in the final measurement.
+
+## Input Configuration
+
+Some configuration options are configurable per input:
+
+* **name_override**: Override the base name of the measurement.
+(Default is the name of the input).
+* **name_prefix**: Specifies a prefix to attach to the measurement name.
+* **name_suffix**: Specifies a suffix to attach to the measurement name.
+* **tags**: A map of tags to apply to a specific input's measurements.
+* **interval**: How often to gather this metric. Normal plugins use a single
+global interval, but if one particular input should be run less or more often,
+you can configure that here.
+
+#### Input Configuration Examples
+
+This is a full working config that will output CPU data to an InfluxDB instance
+at 192.168.59.103:8086, tagging measurements with dc="denver-1". It will output
+measurements at a 10s interval and will collect per-cpu data, dropping any
+fields which begin with `time_`.
+
+```toml
+[global_tags]
+  dc = "denver-1"
+
+[agent]
+  interval = "10s"
+
+# OUTPUTS
+[[outputs.influxdb]]
+  url = "http://192.168.59.103:8086" # required.
+  database = "telegraf" # required.
+  precision = "s"
+
+# INPUTS
+[[inputs.cpu]]
+  percpu = true
+  totalcpu = false
+  # filter all fields beginning with 'time_'
+  fielddrop = ["time_*"]
+```
+
+#### Input Config: tagpass and tagdrop
+
+```toml
+[[inputs.cpu]]
+  percpu = true
+  totalcpu = false
+  fielddrop = ["cpu_time"]
+  # Don't collect CPU data for cpu6 & cpu7
+  [inputs.cpu.tagdrop]
+    cpu = [ "cpu6", "cpu7" ]
+
+[[inputs.disk]]
+  [inputs.disk.tagpass]
+    # tagpass conditions are OR, not AND.
+    # If the (filesystem is ext4 or xfs) OR (the path is /opt or /home)
+    # then the metric passes
+    fstype = [ "ext4", "xfs" ]
+    # Globs can also be used on the tag values
+    path = [ "/opt", "/home*" ]
+```
+
+#### Input Config: fieldpass and fielddrop
+
+```toml
+# Drop all metrics for guest & steal CPU usage
+[[inputs.cpu]]
+  percpu = false
+  totalcpu = true
+  fielddrop = ["usage_guest", "usage_steal"]
+
+# Only store inode related metrics for disks
+[[inputs.disk]]
+  fieldpass = ["inodes*"]
+```
+
+#### Input Config: namepass and namedrop
+
+```toml
+# Drop all metrics about containers for kubelet
+[[inputs.prometheus]]
+  urls = ["http://kube-node-1:4194/metrics"]
+  namedrop = ["container_*"]
+
+# Only store rest client related metrics for kubelet
+[[inputs.prometheus]]
+  urls = ["http://kube-node-1:4194/metrics"]
+  namepass = ["rest_client_*"]
+```
+
+#### Input Config: taginclude and tagexclude
+
+```toml
+# Only include the "cpu" tag in the measurements for the cpu plugin.
+[[inputs.cpu]]
+  percpu = true
+  totalcpu = true
+  taginclude = ["cpu"]
+
+# Exclude the "fstype" tag from the measurements for the disk plugin.
+[[inputs.disk]]
+  tagexclude = ["fstype"]
+```
+
+#### Input config: prefix, suffix, and override
+
+This plugin will emit measurements with the name `cpu_total`
+
+```toml
+[[inputs.cpu]]
+  name_suffix = "_total"
+  percpu = false
+  totalcpu = true
+```
+
+This will emit measurements with the name `foobar`
+
+```toml
+[[inputs.cpu]]
+  name_override = "foobar"
+  percpu = false
+  totalcpu = true
+```
+
+#### Input config: tags
+
+This plugin will emit measurements with two additional tags: `tag1=foo` and
+`tag2=bar`
+
+NOTE: Order matters, the `[inputs.cpu.tags]` table must be at the _end_ of the
+plugin definition.
+
+```toml
+[[inputs.cpu]]
+  percpu = false
+  totalcpu = true
+  [inputs.cpu.tags]
+    tag1 = "foo"
+    tag2 = "bar"
+```
+
+#### Multiple inputs of the same type
+
+Additional inputs (or outputs) of the same type can be specified,
+just define more instances in the config file. It is highly recommended that
+you utilize `name_override`, `name_prefix`, or `name_suffix` config options
+to avoid measurement collisions:
+
+```toml
+[[inputs.cpu]]
+  percpu = false
+  totalcpu = true
+
+[[inputs.cpu]]
+  percpu = true
+  totalcpu = false
+  name_override = "percpu_usage"
+  fielddrop = ["cpu_time*"]
+```
+
+## Output Configuration
+
+Telegraf also supports specifying multiple output sinks to send data to,
+configuring each output sink is different, but examples can be
+found by running `telegraf -sample-config`.
+
+```toml
+[[outputs.influxdb]]
+  urls = [ "http://localhost:8086" ]
+  database = "telegraf"
+  precision = "s"
+  # Drop all measurements that start with "aerospike"
+  namedrop = ["aerospike*"]
+
+[[outputs.influxdb]]
+  urls = [ "http://localhost:8086" ]
+  database = "telegraf-aerospike-data"
+  precision = "s"
+  # Only accept aerospike data:
+  namepass = ["aerospike*"]
+
+[[outputs.influxdb]]
+  urls = [ "http://localhost:8086" ]
+  database = "telegraf-cpu0-data"
+  precision = "s"
+  # Only store measurements where the tag "cpu" matches the value "cpu0"
+  [outputs.influxdb.tagpass]
+    cpu = ["cpu0"]
+```

+# Telegraf Input Data Formats
+
+Telegraf is able to parse the following input data formats into metrics:
+
+1. [InfluxDB Line Protocol](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md#influx)
+1. [JSON](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md#json)
+1. [Graphite](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md#graphite)
+1. [Value](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md#value), ie: 45 or "booyah"
+1. [Nagios](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md#nagios) (exec input only)
+
+Telegraf metrics, like InfluxDB
+[points](https://docs.influxdata.com/influxdb/v0.10/write_protocols/line/),
+are a combination of four basic parts:
+
+1. Measurement Name
+1. Tags
+1. Fields
+1. Timestamp
+
+These four parts are easily defined when using InfluxDB line-protocol as a
+data format. But there are other data formats that users may want to use which
+require more advanced configuration to create usable Telegraf metrics.
+
+Plugins such as `exec` and `kafka_consumer` parse textual data. Up until now,
+these plugins were statically configured to parse just a single
+data format. `exec` mostly only supported parsing JSON, and `kafka_consumer` only
+supported data in InfluxDB line-protocol.
+
+But now we are normalizing the parsing of various data formats across all
+plugins that can support it. You will be able to identify a plugin that supports
+different data formats by the presence of a `data_format` config option, for
+example, in the exec plugin:
+
+```toml
+[[inputs.exec]]
+  ## Commands array
+  commands = ["/tmp/test.sh", "/usr/bin/mycollector --foo=bar"]
+
+  ## measurement name suffix (for separating different commands)
+  name_suffix = "_mycollector"
+
+  ## Data format to consume.
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
+  data_format = "json"
+
+  ## Additional configuration options go here
+```
+
+Each data_format has an additional set of configuration options available, which
+I'll go over below.
+
+# Influx:
+
+There are no additional configuration options for InfluxDB line-protocol. The
+metrics are parsed directly into Telegraf metrics.
+
+#### Influx Configuration:
+
+```toml
+[[inputs.exec]]
+  ## Commands array
+  commands = ["/tmp/test.sh", "/usr/bin/mycollector --foo=bar"]
+
+  ## measurement name suffix (for separating different commands)
+  name_suffix = "_mycollector"
+
+  ## Data format to consume.
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
+  data_format = "influx"
+```

+# JSON:
+
+The JSON data format flattens JSON into metric _fields_.
+NOTE: Only numerical values are converted to fields, and they are converted
+into a float. strings are ignored unless specified as a tag_key (see below).
+
+So for example, this JSON:
+
+```json
+{
+    "a": 5,
+    "b": {
+        "c": 6
+    },
+    "ignored": "I'm a string"
+}
+```
+
+Would get translated into _fields_ of a measurement:
+
+```
+myjsonmetric a=5,b_c=6
+```
+
+The _measurement_ _name_ is usually the name of the plugin,
+but can be overridden using the `name_override` config option.
+
+#### JSON Configuration:
+
+The JSON data format supports specifying "tag keys". If specified, keys
+will be searched for in the root-level of the JSON blob. If the key(s) exist,
+they will be applied as tags to the Telegraf metrics.
+
+For example, if you had this configuration:
+
+```toml
+[[inputs.exec]]
+  ## Commands array
+  commands = ["/tmp/test.sh", "/usr/bin/mycollector --foo=bar"]
+
+  ## measurement name suffix (for separating different commands)
+  name_suffix = "_mycollector"
+
+  ## Data format to consume.
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
+  data_format = "json"
+
+  ## List of tag names to extract from top-level of JSON server response
+  tag_keys = [
+    "my_tag_1",
+    "my_tag_2"
+  ]
+```
+
+with this JSON output from a command:
+
+```json
+{
+    "a": 5,
+    "b": {
+        "c": 6
+    },
+    "my_tag_1": "foo"
+}
+```
+
+Your Telegraf metrics would get tagged with "my_tag_1"
+
+```
+exec_mycollector,my_tag_1=foo a=5,b_c=6
+```
+
+# Value:
+
+The "value" data format translates single values into Telegraf metrics. This
+is done by assigning a measurement name and setting a single field ("value")
+as the parsed metric.
+
+#### Value Configuration:
+
+You **must** tell Telegraf what type of metric to collect by using the
+`data_type` configuration option. Available options are:
+
+1. integer
+2. float or long
+3. string
+4. boolean
+
+**Note:** It is also recommended that you set `name_override` to a measurement
+name that makes sense for your metric, otherwise it will just be set to the
+name of the plugin.
+
+```toml
+[[inputs.exec]]
+  ## Commands array
+  commands = ["cat /proc/sys/kernel/random/entropy_avail"]
+
+  ## override the default metric name of "exec"
+  name_override = "entropy_available"
+
+  ## Data format to consume.
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_INPUT.md
+  data_format = "value"
+  data_type = "integer" # required
+```
+
+# Graphite:
+
+The Graphite data format translates graphite _dot_ buckets directly into
+telegraf measurement names, with a single value field, and without any tags.
+By default, the separator is left as ".", but this can be changed using the
+"separator" argument. For more advanced options,
+Telegraf supports specifying "templates" to translate
+graphite buckets into Telegraf metrics.
+
+Templates are of the form:
+
+```
+"host.mytag.mytag.measurement.measurement.field*"
+```
+
+Where the following keywords exist:
+
+1. `measurement`: specifies that this section of the graphite bucket corresponds
+to the measurement name. This can be specified multiple times.
+2. `field`: specifies that this section of the graphite bucket corresponds
+to the field name. This can be specified multiple times.
+3. `measurement*`: specifies that all remaining elements of the graphite bucket
+correspond to the measurement name.
+4. `field*`: specifies that all remaining elements of the graphite bucket
+correspond to the field name.
+
+Any part of the template that is not a keyword is treated as a tag key. This
+can also be specified multiple times.
+
+NOTE: `field*` cannot be used in conjunction with `measurement*`!
+
+#### Measurement & Tag Templates:
+
+The most basic template is to specify a single transformation to apply to all
+incoming metrics. So the following template:
+
+```toml
+templates = [
+    "region.region.measurement*"
+]
+```
+
+would result in the following Graphite -> Telegraf transformation.
+
+```
+us.west.cpu.load 100
+=> cpu.load,region=us.west value=100
+```
+
+#### Field Templates:
+
+The field keyword tells Telegraf to give the metric that field name.
+So the following template:
+
+```toml
+separator = "_"
+templates = [
+    "measurement.measurement.field.field.region"
+]
+```
+
+would result in the following Graphite -> Telegraf transformation.
+
+```
+cpu.usage.idle.percent.eu-east 100
+=> cpu_usage,region=eu-east idle_percent=100
+```
+
+The field key can also be derived from all remaining elements of the graphite
+bucket by specifying `field*`:
+
+```toml
+separator = "_"
+templates = [
+    "measurement.measurement.region.field*"
+]
+```
+
+which would result in the following Graphite -> Telegraf transformation.
+
+```
+cpu.usage.eu-east.idle.percentage 100
+=> cpu_usage,region=eu-east idle_percentage=100
+```
+
+#### Filter Templates:
+
+Users can also filter the template(s) to use based on the name of the bucket,
+using glob matching, like so:
+
+```toml
+templates = [
+    "cpu.* measurement.measurement.region",
+    "mem.* measurement.measurement.host"
+]
+```
+
+which would result in the following transformation:
+
+```
+cpu.load.eu-east 100
+=> cpu_load,region=eu-east value=100
+
+mem.cached.localhost 256
+=> mem_cached,host=localhost value=256
+```
+
+#### Adding Tags:
+
+Additional tags can be added to a metric that don't exist on the received metric.
+You can add additional tags by specifying them after the pattern.
+Tags have the same format as the line protocol.
+Multiple tags are separated by commas.
+
+```toml
+templates = [
+    "measurement.measurement.field.region datacenter=1a"
+]
+```
+
+would result in the following Graphite -> Telegraf transformation.
+
+```
+cpu.usage.idle.eu-east 100
+=> cpu_usage,region=eu-east,datacenter=1a idle=100
+```
+
+There are many more options available,
+[More details can be found here](https://github.com/influxdata/influxdb/tree/master/services/graphite#templates)
+
+#### Graphite Configuration:
+
+```toml

+  data_format = "graphite"
+
+  ## This string will be used to join the matched values.
+  separator = "_"
+
+  ## Each template line requires a template pattern. It can have an optional
+  ## filter before the template and separated by spaces. It can also have optional extra
+  ## tags following the template. Multiple tags should be separated by commas and no spaces
+  ## similar to the line protocol format. There can be only one default template.

+# Telegraf Output Data Formats
+
+Telegraf is able to serialize metrics into the following output data formats:
+
+1. [InfluxDB Line Protocol](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md#influx)
+1. [JSON](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md#json)
+1. [Graphite](https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md#graphite)
+
+Telegraf metrics, like InfluxDB
+[points](https://docs.influxdata.com/influxdb/v0.10/write_protocols/line/),
+are a combination of four basic parts:
+
+1. Measurement Name
+1. Tags
+1. Fields
+1. Timestamp
+
+In InfluxDB line protocol, these 4 parts are easily defined in textual form:
+
+```
+measurement_name[,tag1=val1,...]  field1=val1[,field2=val2,...]  [timestamp]
+```
+
+For Telegraf outputs that write textual data (such as `kafka`, `mqtt`, and `file`),
+InfluxDB line protocol was originally the only available output format. But now
+we are normalizing telegraf metric "serializers" into a
+[plugin-like interface](https://github.com/influxdata/telegraf/tree/master/plugins/serializers)
+across all output plugins that can support it.
+You will be able to identify a plugin that supports different data formats
+by the presence of a `data_format`
+config option, for example, in the `file` output plugin:
+
+```toml
+[[outputs.file]]
+  ## Files to write to, "stdout" is a specially handled file.
+  files = ["stdout"]
+
+  ## Data format to output.
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md
+  data_format = "influx"
+
+  ## Additional configuration options go here
+```
+
+Each data_format has an additional set of configuration options available, which
+I'll go over below.
+
+# Influx:
+
+There are no additional configuration options for InfluxDB line-protocol. The
+metrics are serialized directly into InfluxDB line-protocol.
+
+### Influx Configuration:
+
+```toml
+[[outputs.file]]
+  ## Files to write to, "stdout" is a specially handled file.
+  files = ["stdout", "/tmp/metrics.out"]
+
+  ## Data format to output.
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md
+  data_format = "influx"
+```
+
+# Graphite:
+
+The Graphite data format translates Telegraf metrics into _dot_ buckets. A
+template can be specified for the output of Telegraf metrics into Graphite
+buckets. The default template is:
+
+```
+template = "host.tags.measurement.field"
+```
+
+In the above template, we have four parts:
+
+1. _host_ is a tag key. This can be any tag key that is in the Telegraf
+metric(s). If the key doesn't exist, it will be ignored. If it does exist, the
+tag value will be filled in.
+1. _tags_ is a special keyword that outputs all remaining tag values, separated
+by dots and in alphabetical order (by tag key). These will be filled after all
+tag keys are filled.
+1. _measurement_ is a special keyword that outputs the measurement name.
+1. _field_ is a special keyword that outputs the field name.
+
+Which means the following influx metric -> graphite conversion would happen:
+
+```
+cpu,cpu=cpu-total,dc=us-east-1,host=tars usage_idle=98.09,usage_user=0.89 1455320660004257758
+=>
+tars.cpu-total.us-east-1.cpu.usage_user 0.89 1455320690
+tars.cpu-total.us-east-1.cpu.usage_idle 98.09 1455320690
+```
+
+### Graphite Configuration:
+
+```toml
+[[outputs.file]]
+  ## Files to write to, "stdout" is a specially handled file.
+  files = ["stdout", "/tmp/metrics.out"]
+
+  ## Data format to output.
+  ## Each data format has it's own unique set of configuration options, read
+  ## more about them here:
+  ## https://github.com/influxdata/telegraf/blob/master/docs/DATA_FORMATS_OUTPUT.md
+  data_format = "graphite"
+
+  # prefix each graphite bucket
+  prefix = "telegraf"
+  # graphite template
+  template = "host.tags.measurement.field"
+```
+
+# JSON:
+
+The JSON data format serialized Telegraf metrics in json format. The format is:
+
+```json
+{
+   "fields":{
+      "field_1":30,
+      "field_2":4,
+      "field_N":59,

+# Running Telegraf as a Windows Service
+
+If you have tried to install Go binaries as Windows Services with the **sc.exe**
+tool you may have seen that the service errors and stops running after a while.
+
+**NSSM** (the Non-Sucking Service Manager) is a tool that helps you in a 
+[number of scenarios](http://nssm.cc/scenarios) including running Go binaries
+that were not specifically designed to run only in Windows platforms.
+
+## NSSM Installation via Chocolatey
+
+You can install [Chocolatey](https://chocolatey.org/) and [NSSM](http://nssm.cc/) 
+with these commands
+
+```powershell
+iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))
+choco install -y nssm
+```
+
+## Installing Telegraf as a Windows Service with NSSM
+
+You can download the latest Telegraf Windows binaries (still Experimental at 
+the moment) from [the Telegraf Github repo](https://github.com/influxdata/telegraf).
+
+Then you can create a C:\telegraf folder, unzip the binary there and modify the 
+**telegraf.conf** sample to allocate the metrics you want to send to **InfluxDB**.
+
+Once you have NSSM installed in your system, the process is quite straightforward.
+You only need to type this command in your Windows shell
+
+```powershell
+nssm install Telegraf c:\telegraf\telegraf.exe -config c:\telegraf\telegraf.config
+```
+
+And now your service will be installed in Windows and you will be able to start and
+stop it gracefully

+## Telegraf Plugin: Aerospike
+
+#### Plugin arguments:
+- **servers** string array: List of aerospike servers to query (def: 127.0.0.1:3000)
+
+#### Description
+
+The aerospike plugin queries aerospike server(s) and get node statistics. It also collects stats for
+all the configured namespaces.
+
+For what the measurements mean, please consult the [Aerospike Metrics Reference Docs](http://www.aerospike.com/docs/reference/metrics).
+
+The metric names, to make it less complicated in querying, have replaced all `-` with `_` as Aerospike metrics come in both forms (no idea why).

+### Description
+
+```
+dirty_data
+  Amount of dirty data for this backing device in the cache. Continuously
+  updated unlike the cache set's version, but may be slightly off.
+
+bypassed
+  Amount of IO (both reads and writes) that has bypassed the cache
+
+
+cache_bypass_hits
+cache_bypass_misses
+  Hits and misses for IO that is intended to skip the cache are still counted,
+  but broken out here.
+
+cache_hits
+cache_misses
+cache_hit_ratio
+  Hits and misses are counted per individual IO as bcache sees them; a
+  partial hit is counted as a miss.
+
+cache_miss_collisions
+  Counts instances where data was going to be inserted into the cache from a
+  cache miss, but raced with a write and data was already present (usually 0
+  since the synchronization for cache misses was rewritten)
+
+cache_readaheads
+  Count of times readahead occurred.
+```
+
+# Example output
+
+Using this configuration:
+
+```
+[bcache]
+  # Bcache sets path
+  # If not specified, then default is:
+  # bcachePath = "/sys/fs/bcache"
+  #
+  # By default, telegraf gather stats for all bcache devices
+  # Setting devices will restrict the stats to the specified
+  # bcache devices.
+  # bcacheDevs = ["bcache0", ...]
+```
+
+When run with:
+
+```
+./telegraf -config telegraf.conf -input-filter bcache -test
+```
+
+It produces:

+# Telegraf plugin: Cassandra
+
+#### Plugin arguments:
+- **context** string: Context root used for jolokia url
+- **servers** []string: List of servers with the format "<user:passwd@><host>:port"
+- **metrics** []string: List of Jmx paths that identify mbeans attributes
+
+#### Description
+
+The Cassandra plugin collects Cassandra/JVM metrics exposed as MBean's attributes through jolokia REST endpoint. All metrics are collected for each server configured.
+
+See: https://jolokia.org/ and [Cassandra Documentation](http://docs.datastax.com/en/cassandra/3.x/cassandra/operations/monitoringCassandraTOC.html)
+
+# Measurements:
+Cassandra plugin produces one or more measurements for each metric configured, adding Server's name  as `host` tag. More than one measurement is generated when querying table metrics with a wildcard for the keyspace or table name.
+
+Given a configuration like:
+
+```toml
+[[inputs.cassandra]]
+  context = "/jolokia/read"
+  servers = [":8778"]
+  metrics = ["/java.lang:type=Memory/HeapMemoryUsage"]
+```
+
+The collected metrics will be:
+
+```
+javaMemory,host=myHost,mname=HeapMemoryUsage HeapMemoryUsage_committed=1040187392,HeapMemoryUsage_init=1050673152,HeapMemoryUsage_max=1040187392,HeapMemoryUsage_used=368155000 1459551767230567084
+```
+
+# Useful Metrics:
+
+Here is a list of metrics that might be useful to monitor your cassandra cluster. This was put together from multiple sources on the web.

+# Ceph Storage Input Plugin
+
+Collects performance metrics from the MON and OSD nodes in a Ceph storage cluster.  
+
+The plugin works by scanning the configured SocketDir for OSD and MON socket files.  When it finds
+a MON socket, it runs **ceph --admin-daemon $file perfcounters_dump**. For OSDs it runs **ceph --admin-daemon $file perf dump** 
+
+The resulting JSON is parsed and grouped into collections, based on top-level key.  Top-level keys are
+used as collection tags, and all sub-keys are flattened. For example:
+
+```
+ { 
+   "paxos": { 
+     "refresh": 9363435,
+     "refresh_latency": { 
+       "avgcount": 9363435,
+       "sum": 5378.794002000
+     }
+   }
+ }
+```
+
+Would be parsed into the following metrics, all of which would be tagged with collection=paxos:
+
+ - refresh = 9363435
+ - refresh_latency.avgcount: 9363435
+ - refresh_latency.sum: 5378.794002000
+
+
+### Configuration:
+
+```
+# Collects performance metrics from the MON and OSD nodes in a Ceph storage cluster.
+[[inputs.ceph]]
+  ## All configuration values are optional, defaults are shown below
+
+  ## location of ceph binary
+  ceph_binary = "/usr/bin/ceph"
+
+  ## directory in which to look for socket files
+  socket_dir = "/var/run/ceph"
+
+  ## prefix of MON and OSD socket files, used to determine socket type
+  mon_prefix = "ceph-mon"
+  osd_prefix = "ceph-osd"
+
+  ## suffix used to identify socket files
+  socket_suffix = "asok"
+```
+
+### Measurements & Fields:
+
+All fields are collected under the **ceph** measurement and stored as float64s. For a full list of fields, see the sample perf dumps in ceph_test.go. 
+
+
+### Tags:
+
+All measurements will have the following tags:
+
+- type: either 'osd' or 'mon' to indicate which type of node was queried
+- id: a unique string identifier, parsed from the socket file name for the node
+- collection: the top-level key under which these fields were reported. Possible values are:
+  - for MON nodes:
+    - cluster
+    - leveldb
+    - mon
+    - paxos
+    - throttle-mon_client_bytes
+    - throttle-mon_daemon_bytes
+    - throttle-msgr_dispatch_throttler-mon
+  - for OSD nodes:
+    - WBThrottle
+    - filestore
+    - leveldb
+    - mutex-FileJournal::completions_lock
+    - mutex-FileJournal::finisher_lock
+    - mutex-FileJournal::write_lock
+    - mutex-FileJournal::writeq_lock
+    - mutex-JOS::ApplyManager::apply_lock
+    - mutex-JOS::ApplyManager::com_lock
+    - mutex-JOS::SubmitManager::lock
+    - mutex-WBThrottle::lock
+    - objecter
+    - osd
+    - recoverystate_perf
+    - throttle-filestore_bytes
+    - throttle-filestore_ops
+    - throttle-msgr_dispatch_throttler-client
+    - throttle-msgr_dispatch_throttler-cluster
+    - throttle-msgr_dispatch_throttler-hb_back_server
+    - throttle-msgr_dispatch_throttler-hb_front_serve
+    - throttle-msgr_dispatch_throttler-hbclient
+    - throttle-msgr_dispatch_throttler-ms_objecter
+    - throttle-objecter_bytes
+    - throttle-objecter_ops
+    - throttle-osd_client_bytes
+    - throttle-osd_client_messages
+

+# chrony Input Plugin
+
+Get standard chrony metrics, requires chronyc executable.
+
+Below is the documentation of the various headers returned by `chronyc tracking`.
+
+- Reference ID - This is the refid and name (or IP address) if available, of the
+server to which the computer is currently synchronised. If this is 127.127.1.1
+it means the computer is not synchronised to any external source and that you
+have the ‘local’ mode operating (via the local command in chronyc (see section local),
+or the local directive in the ‘/etc/chrony.conf’ file (see section local)).
+- Stratum - The stratum indicates how many hops away from a computer with an attached
+reference clock we are. Such a computer is a stratum-1 computer, so the computer in the
+example is two hops away (i.e. a.b.c is a stratum-2 and is synchronised from a stratum-1).
+- Ref time - This is the time (UTC) at which the last measurement from the reference
+source was processed.
+- System time - In normal operation, chronyd never steps the system clock, because any
+jump in the timescale can have adverse consequences for certain application programs.
+Instead, any error in the system clock is corrected by slightly speeding up or slowing
+down the system clock until the error has been removed, and then returning to the system
+clock’s normal speed. A consequence of this is that there will be a period when the
+system clock (as read by other programs using the gettimeofday() system call, or by the
+date command in the shell) will be different from chronyd's estimate of the current true
+time (which it reports to NTP clients when it is operating in server mode). The value
+reported on this line is the difference due to this effect.
+- Last offset - This is the estimated local offset on the last clock update.
+- RMS offset - This is a long-term average of the offset value.
+- Frequency - The ‘frequency’ is the rate by which the system’s clock would be
+wrong if chronyd was not correcting it. It is expressed in ppm (parts per million).
+For example, a value of 1ppm would mean that when the system’s clock thinks it has
+advanced 1 second, it has actually advanced by 1.000001 seconds relative to true time.
+- Residual freq - This shows the ‘residual frequency’ for the currently selected
+reference source. This reflects any difference between what the measurements from the
+reference source indicate the frequency should be and the frequency currently being used.
+The reason this is not always zero is that a smoothing procedure is applied to the
+frequency. Each time a measurement from the reference source is obtained and a new
+residual frequency computed, the estimated accuracy of this residual is compared with the
+estimated accuracy (see ‘skew’ next) of the existing frequency value. A weighted average
+is computed for the new frequency, with weights depending on these accuracies. If the
+measurements from the reference source follow a consistent trend, the residual will be
+driven to zero over time.
+- Skew - This is the estimated error bound on the frequency.
+- Root delay - This is the total of the network path delays to the stratum-1 computer
+from which the computer is ultimately synchronised. In certain extreme situations, this
+value can be negative. (This can arise in a symmetric peer arrangement where the computers’
+frequencies are not tracking each other and the network delay is very short relative to the
+turn-around time at each computer.)
+- Root dispersion - This is the total dispersion accumulated through all the computers
+back to the stratum-1 computer from which the computer is ultimately synchronised.
+Dispersion is due to system clock resolution, statistical measurement variations etc.
+- Leap status - This is the leap status, which can be Normal, Insert second,
+Delete second or Not synchronised.
+
+### Configuration:
+
+```toml
+# Get standard chrony metrics, requires chronyc executable.
+[[inputs.chrony]]
+  ## If true, chronyc tries to perform a DNS lookup for the time server.
+  # dns_lookup = false
+```
+
+### Measurements & Fields:
+
+- chrony
+    - last_offset (float, seconds)
+    - rms_offset (float, seconds)
+    - frequency (float, ppm)
+    - residual_freq (float, ppm)
+    - skew (float, ppm)
+    - root_delay (float, seconds)
+    - root_dispersion (float, seconds)
+    - update_interval (float, seconds)
+
+### Tags:
+
+- All measurements have the following tags:
+    - reference_id
+    - stratum
+    - leap_status
+
+### Example Output:
+
+```
+$ telegraf -config telegraf.conf -input-filter chrony -test
+* Plugin: chrony, Collection 1
+> chrony,leap_status=normal,reference_id=192.168.1.1,stratum=3 frequency=-35.657,last_offset=-0.000013616,residual_freq=-0,rms_offset=0.000027073,root_delay=0.000644,root_dispersion=0.003444,skew=0.001,update_interval=1031.2 1463750789687639161

+# Amazon CloudWatch Statistics Input
+
+This plugin will pull Metric Statistics from Amazon CloudWatch.
+
+### Amazon Authentication
+
+This plugin uses a credential chain for Authentication with the CloudWatch
+API endpoint. In the following order the plugin will attempt to authenticate.
+1. Assumed credentials via STS if `role_arn` attribute is specified (source credentials are evaluated from subsequent rules)
+2. Explicit credentials from `access_key`, `secret_key`, and `token` attributes
+3. Shared profile from `profile` attribute
+4. [Environment Variables](https://github.com/aws/aws-sdk-go/wiki/configuring-sdk#environment-variables)
+5. [Shared Credentials](https://github.com/aws/aws-sdk-go/wiki/configuring-sdk#shared-credentials-file)
+6. [EC2 Instance Profile](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/iam-roles-for-amazon-ec2.html)
+
+### Configuration:
+
+```toml
+[[inputs.cloudwatch]]
+  ## Amazon Region (required)
+  region = 'us-east-1'
+
+  ## Requested CloudWatch aggregation Period (required - must be a multiple of 60s)
+  period = '1m'
+
+  ## Collection Delay (required - must account for metrics availability via CloudWatch API)
+  delay = '1m'
+
+  ## Override global run interval (optional - defaults to global interval)
+  ## Recomended: use metric 'interval' that is a multiple of 'period' to avoid
+  ## gaps or overlap in pulled data
+  interval = '1m'
+
+  ## Metric Statistic Namespace (required)
+  namespace = 'AWS/ELB'
+
+  ## Metrics to Pull (optional)
+  ## Defaults to all Metrics in Namespace if nothing is provided
+  ## Refreshes Namespace available metrics every 1h
+  [[inputs.cloudwatch.metrics]]
+    names = ['Latency', 'RequestCount']
+
+    ## Dimension filters for Metric (optional)
+    [[inputs.cloudwatch.metrics.dimensions]]
+      name = 'LoadBalancerName'
+      value = 'p-example'
+
+    [[inputs.cloudwatch.metrics.dimensions]]
+      name = 'AvailabilityZone'
+      value = '*'
+```
+#### Requirements and Terminology
+
+Plugin Configuration utilizes [CloudWatch concepts](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html) and access pattern to allow monitoring of any CloudWatch Metric.
+
+- `region` must be a valid AWS [Region](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html#CloudWatchRegions) value
+- `period` must be a valid CloudWatch [Period](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html#CloudWatchPeriods) value
+- `namespace` must be a valid CloudWatch [Namespace](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html#Namespace) value
+- `names` must be valid CloudWatch [Metric](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html#Metric) names
+- `dimensions` must be valid CloudWatch [Dimension](http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/cloudwatch_concepts.html#Dimension) name/value pairs
+
+Omitting or specifying a value of `'*'` for a dimension value configures all available metrics that contain a dimension with the specified name
+to be retrieved. If specifying >1 dimension, then the metric must contain *all* the configured dimensions where the the value of the
+wildcard dimension is ignored.
+
+Example:
+```
+[[inputs.cloudwatch.metrics]]
+  names = ['Latency']
+
+  ## Dimension filters for Metric (optional)
+  [[inputs.cloudwatch.metrics.dimensions]]
+    name = 'LoadBalancerName'
+    value = 'p-example'
+
+  [[inputs.cloudwatch.metrics.dimensions]]
+    name = 'AvailabilityZone'
+    value = '*'
+```
+
+If the following ELBs are available:
+- name: `p-example`, availabilityZone: `us-east-1a`
+- name: `p-example`, availabilityZone: `us-east-1b`
+- name: `q-example`, availabilityZone: `us-east-1a`
+- name: `q-example`, availabilityZone: `us-east-1b`
+
+
+Then 2 metrics will be output:
+- name: `p-example`, availabilityZone: `us-east-1a`
+- name: `p-example`, availabilityZone: `us-east-1b`
+
+If the `AvailabilityZone` wildcard dimension was omitted, then a single metric (name: `p-example`)
+would be exported containing the aggregate values of the ELB across availability zones.
+
+#### Restrictions and Limitations
+- CloudWatch metrics are not available instantly via the CloudWatch API. You should adjust your collection `delay` to account for this lag in metrics availability based on your [monitoring subscription level](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-cloudwatch-new.html)
+- CloudWatch API usage incurs cost - see [GetMetricStatistics Pricing](https://aws.amazon.com/cloudwatch/pricing/)
+
+### Measurements & Fields:
+
+Each CloudWatch Namespace monitored records a measurement with fields for each available Metric Statistic
+Namespace and Metrics are represented in [snake case](https://en.wikipedia.org/wiki/Snake_case)
+
+- cloudwatch_{namespace}
+  - {metric}_sum         (metric Sum value)
+  - {metric}_average     (metric Average value)
+  - {metric}_minimum     (metric Minimum value)
+  - {metric}_maximum     (metric Maximum value)
+  - {metric}_sample_count (metric SampleCount value)
+
+
+### Tags:
+Each measurement is tagged with the following identifiers to uniquely identify the associated metric
+Tag Dimension names are represented in [snake case](https://en.wikipedia.org/wiki/Snake_case)
+
+- All measurements have the following tags:
+  - region           (CloudWatch Region)
+  - unit             (CloudWatch Metric Unit)
+  - {dimension-name} (Cloudwatch Dimension value - one for each metric dimension)
+
+### Example Output:
+
+```
+$ ./telegraf -config telegraf.conf -input-filter cloudwatch -test
+> cloudwatch_aws_elb,load_balancer_name=p-example,region=us-east-1,unit=seconds latency_average=0.004810798017284538,latency_maximum=0.1100282669067383,latency_minimum=0.0006084442138671875,latency_sample_count=4029,latency_sum=19.382705211639404 1459542420000000000

+# Conntrack Plugin
+
+Collects stats from Netfilter's conntrack-tools.
+
+The conntrack-tools provide a mechanism for tracking various aspects of
+network connections as they are processed by netfilter. At runtime, 
+conntrack exposes many of those connection statistics within /proc/sys/net.
+Depending on your kernel version, these files can be found in either
+/proc/sys/net/ipv4/netfilter or /proc/sys/net/netfilter and will be
+prefixed with either ip_ or nf_.  This plugin reads the files specified 
+in its configuration and publishes each one as a field, with the prefix
+normalized to ip_.  
+
+In order to simplify configuration in a heterogeneous environment, a superset
+of directory and filenames can be specified.  Any locations that don't exist
+will be ignored.
+
+For more information on conntrack-tools, see the 
+[Netfilter Documentation](http://conntrack-tools.netfilter.org/).
+
+
+### Configuration:
+
+```toml
+ # Collects conntrack stats from the configured directories and files.
+ [[inputs.conntrack]]
+   ## The following defaults would work with multiple versions of conntrack.
+   ## Note the nf_ and ip_ filename prefixes are mutually exclusive across
+   ## kernel versions, as are the directory locations.
+
+   ## Superset of filenames to look for within the conntrack dirs.
+   ## Missing files will be ignored.
+   files = ["ip_conntrack_count","ip_conntrack_max",
+            "nf_conntrack_count","nf_conntrack_max"]
+
+   ## Directories to search within for the conntrack files above.
+   ## Missing directrories will be ignored.
+   dirs = ["/proc/sys/net/ipv4/netfilter","/proc/sys/net/netfilter"]
+```
+
+### Measurements & Fields:
+
+- conntrack
+    - ip_conntrack_count (int, count): the number of entries in the conntrack table 
+    - ip_conntrack_max (int, size): the max capacity of the conntrack table
+
+### Tags:
+
+This input does not use tags.
+
+### Example Output:
+
+```
+$ ./telegraf -config telegraf.conf -input-filter conntrack -test
+conntrack,host=myhost ip_conntrack_count=2,ip_conntrack_max=262144 1461620427667995735
