+## v0.3.0 [unreleased]
 
 ### 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

-- 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.

-## 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** 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`
+- `twemproxy` plugin: `prefix` option removed.
+- `procstat` cpu measurements are now prepended with `cpu_time_` instead of
+only `cpu_`
 - 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`)

+# Telegraf Configuration
+
+## Plugin Configuration
+
+There are some configuration options that are configurable per plugin:
+
+* **name_override**: Override the base name of the measurement.
+(Default is the name of the plugin).
+* **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 plugin's measurements.
+
+### Plugin Filters
+
+There are also filters that can be configured per plugin:
+
+* **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 glob match against field names
+and if it matches, the field is emitted.
+* **drop**: The inverse of pass, if a field name matches, it is not emitted.
+* **tagpass**: tag names and arrays of strings that are used to filter
+measurements by the current plugin. 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.
+* **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.
+
+### Plugin 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
+[tags]
+  dc = "denver-1"
+
+[agent]
+  interval = "10s"
+
+# OUTPUTS
+[outputs]
+[[outputs.influxdb]]
+  url = "http://192.168.59.103:8086" # required.
+  database = "telegraf" # required.
+  precision = "s"
+
+# PLUGINS
+[plugins]
+[[plugins.cpu]]
+  percpu = true
+  totalcpu = false
+  # filter all fields beginning with 'time_'
+  drop = ["time_*"]
+```
+
+### Plugin Config: tagpass and tagdrop
+
+```toml
+[plugins]
+[[plugins.cpu]]
+  percpu = true
+  totalcpu = false
+  drop = ["cpu_time"]
+  # Don't collect CPU data for cpu6 & cpu7
+  [plugins.cpu.tagdrop]
+    cpu = [ "cpu6", "cpu7" ]
+
+[[plugins.disk]]
+  [plugins.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*" ]
+```
+
+### Plugin Config: pass and drop
+
+```toml
+# Drop all metrics for guest & steal CPU usage
+[[plugins.cpu]]
+  percpu = false
+  totalcpu = true
+  drop = ["usage_guest", "usage_steal"]
+
+# Only store inode related metrics for disks
+[[plugins.disk]]
+  pass = ["inodes*"]
+```
+
+### Plugin config: prefix, suffix, and override
+
+This plugin will emit measurements with the name `cpu_total`
+
+```toml
+[[plugins.cpu]]
+  name_suffix = "_total"
+  percpu = false
+  totalcpu = true
+```
+
+This will emit measurements with the name `foobar`
+
+```toml
+[[plugins.cpu]]
+  name_override = "foobar"
+  percpu = false
+  totalcpu = true
+```
+
+### Plugin config: tags
+
+This plugin will emit measurements with two additional tags: `tag1=foo` and
+`tag2=bar`
+
+```toml
+[[plugins.cpu]]
+  percpu = false
+  totalcpu = true
+  [plugins.cpu.tags]
+    tag1 = "foo"
+    tag2 = "bar"
+```
+
+### Multiple plugins of the same type
+
+Additional plugins (or outputs) of the same type can be specified,
+just define more instances in the config file:
+
+```toml
+[[plugins.cpu]]
+  percpu = false
+  totalcpu = true
+
+[[plugins.cpu]]
+  percpu = true
+  totalcpu = false
+  drop = ["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`.
+
+Outputs also support the same configurable options as plugins
+(pass, drop, tagpass, tagdrop), added in 0.2.4
+
+```toml
+[[outputs.influxdb]]
+  urls = [ "http://localhost:8086" ]
+  database = "telegraf"
+  precision = "s"
+  # Drop all measurements that start with "aerospike"
+  drop = ["aerospike*"]
+
+[[outputs.influxdb]]
+  urls = [ "http://localhost:8086" ]
+  database = "telegraf-aerospike-data"
+  precision = "s"
+  # Only accept aerospike data:
+  pass = ["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"]
+```

-### Input Plugin Guidelines
+### Plugin Guidelines
 
-* A plugin must conform to the `telegraf.Input` interface.
-* Input Plugins should call `inputs.Add` in their `init` function to register themselves.
+* A plugin must conform to the `plugins.Plugin` interface.
+* 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.
-* Input Plugins must be added to the
-`github.com/influxdata/telegraf/plugins/inputs/all/all.go` file.
+* 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.
 
-Let's say you've written a plugin that emits metrics about processes on the
-current host.
+### Plugin interface
 
-### Input Plugin Example
+```go
+type Plugin interface {
+    SampleConfig() string
+    Description() string
+    Gather(Accumulator) error
+}
+
+type Accumulator interface {
+    Add(measurement string,
+        value interface{},
+        tags map[string]string,
+        timestamp ...time.Time)
+    AddFields(measurement string,
+        fields map[string]interface{},
+        tags map[string]string,
+        timestamp ...time.Time)
+}
+```
+
+### Accumulator
+
+The way that a plugin emits metrics is by interacting with the Accumulator.
+
+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"`.
+
+The `AddFieldsWithTime` 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.
+
+Let's say you've written a plugin that emits metrics about processes on the current host.
+
+```go
+
+type Process struct {
+    CPUTime float64
+    MemoryBytes int64
+    PID int
+}
+
+func Gather(acc plugins.Accumulator) error {
+    for _, process := range system.Processes() {
+        tags := map[string]string {
+            "pid": fmt.Sprintf("%d", process.Pid),

-
-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:

-  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"

+running on, or from other services, and writing them into InfluxDB.
 
 Design goals are to have a minimal memory footprint with a plugin system so
 that developers in the community can easily add support for collecting metrics
 from well known services (like Hadoop, Postgres, or Redis) and third party
 APIs (like Mailchimp, AWS CloudWatch, or Google Analytics).
 
-New input and output plugins are designed to be easy to contribute,

-$ telegraf -help
-Telegraf, The plugin-driven server agent for collecting and reporting metrics.
+* Run `telegraf -sample-config > telegraf.conf` to create an initial configuration.
+* Or run `telegraf -sample-config -filter cpu:mem -outputfilter influxdb > telegraf.conf`.
+to create a config file with only CPU and memory plugins defined, and InfluxDB
+output defined.
+* Edit the configuration to match your needs.
+* Run `telegraf -config telegraf.conf -test` to output one full measurement
+sample to STDOUT. NOTE: you may want to run as the telegraf user if you are using
+the linux packages `sudo -u telegraf telegraf -config telegraf.conf -test`
+* Run `telegraf -config telegraf.conf` to gather and send metrics to configured outputs.
+* Run `telegraf -config telegraf.conf -filter system:swap`.
+to run telegraf with only the system & swap plugins defined in the config.
 
-Usage:
+## Telegraf Options
 
-  telegraf <flags>
+Telegraf has a few options you can configure under the `agent` section of the
+config.
 
-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 :
-  -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
-
-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
-
-  # run telegraf, enabling the cpu & memory input, and influxdb output plugins
-  telegraf -config telegraf.conf -input-filter cpu:mem -output-filter influxdb
-```
+* **hostname**: The hostname is passed as a tag. By default this will be
+the value returned by `hostname` on the machine running Telegraf.
+You can override that value here.
+* **interval**: How often to gather metrics. Uses a simple number +
+unit parser, e.g. "10s" for 10 seconds or "5m" for 5 minutes.
+* **debug**: Set to true to gather and send metrics to STDOUT as well as
+InfluxDB.

-const usage = `Telegraf, The plugin-driven server agent for collecting and reporting metrics.
-
-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
-
-  # run telegraf, enabling the cpu & memory input, and influxdb output plugins
-  telegraf -config telegraf.conf -input-filter cpu:mem -output-filter influxdb

-# 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"]

-
-# 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
-[[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 = "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.
-  ## Templates support below format:
-  ## 1. filter + template
-  ## 2. filter + template + extra tag(s)
-  ## 3. filter + template with field key
-  ## 4. default template
-  templates = [

-# 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
-```

-  data_format = "graphite"
-
-  # prefix each graphite bucket
-  prefix = "telegraf"
-  # graphite template
-  template = "host.tags.measurement.field"

-# 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
