+
+## 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)
+- More info on serializing _outgoing_ data formats can be found
+[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.

+
+### Release Notes
+- Statsd timing measurements are now aggregated into a single measurement with
+fields.
+- Graphite output now inserts tags into the bucket in alphabetical order.
+- Normalized TLS/SSL support for output plugins: MQTT, AMQP, Kafka
+- `verify_ssl` config option was removed from Kafka because it was actually

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

-# 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"]

-## Plugins
+## Adding a dependency
 
-This section is for developers who want to create new collection plugins.
+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 as well as makes it easy for developers
+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 plugins.
+and submit new inputs.
 
-### Plugin Guidelines
+### Input Plugin Guidelines
 
-* 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.
+* 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.
-* To be available within Telegraf itself, plugins must add themselves to the
-`github.com/influxdb/telegraf/plugins/all/all.go` file.
+* 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.
 
-### Plugin interface
+Let's say you've written a plugin that emits metrics about processes on the
+current host.
 
-```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),

+## 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. This can be "json", "influx" or "graphite"
+  ## 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)
+}

 from well known services (like Hadoop, Postgres, or Redis) and third party
 APIs (like Mailchimp, AWS CloudWatch, or Google Analytics).

-## Telegraf Options
+Usage:
 
-Telegraf has a few options you can configure under the `agent` section of the
-config.
+  telegraf <flags>
 
-* **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.
+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 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`
+
+## `[global_tags]` Configuration
+
+Global tags can be specific 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_buffer_limit**: Telegraf will cache metric_buffer_limit metrics
+for each output, and will flush this buffer on a successful write.
+* **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().
+
+## `[inputs.xxx]` Configuration
+
+There are some configuration options that 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 Filters
+
+There are also filters that can be configured per input:
+
+* **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.
+* **fielddrop**: 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 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.
+
+#### 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_'
+  drop = ["time_*"]
+```
+
+#### Input Config: tagpass and tagdrop
+
+```toml
+[[inputs.cpu]]
+  percpu = true
+  totalcpu = false
+  drop = ["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: 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`
+
+```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"
+  drop = ["cpu_time*"]
+```
+
+## `[outputs.xxx]` 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 inputs
+(namepass, namedrop, tagpass, tagdrop)
+
+```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 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. This can be "json", "influx" or "graphite"
+  ## 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. This can be "json", "influx" or "graphite"
+  ## 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_. For example, this JSON:
+
+```json
+{
+    "a": 5,
+    "b": {
+        "c": 6
+    }
+}
+```
+
+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. This can be "json", "influx" or "graphite"
+  ## 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
+```
+
+## Graphite:
+
+The Graphite data format translates graphite _dot_ buckets directly into
+telegraf measurement names, with a single value field, and without any tags. For
+more advanced options, Telegraf supports specifying "templates" to translate
+graphite buckets into Telegraf metrics.
+
+#### Separator:
+
+You can specify a separator to use for the parsed metrics.
+By default, it will leave the metrics with a "." separator.
+Setting `separator = "_"` will translate:
+
+```
+cpu.usage.idle 99
+=> cpu_usage_idle value=99
+```
+
+#### Measurement/Tag Templates:
+
+The most basic template is to specify a single transformation to apply to all
+incoming metrics. _measurement_ is a special keyword that tells Telegraf which
+parts of the graphite bucket to combine into the measurement name. It can have a
+trailing `*` to indicate that the remainder of the metric should be used.
+Other words are considered tag keys. So the following template:
+
+```toml
+templates = [
+    "region.measurement*"
+]
+```
+
+would result in the following Graphite -> Telegraf transformation.
+
+```
+us-west.cpu.load 100
+=> cpu.load,region=us-west value=100
+```
+
+#### Field Templates:
+
+There is also a _field_ keyword, which can only be specified once.
+The field keyword tells Telegraf to give the metric that field name.
+So the following template:
+
+```toml
+templates = [
+    "measurement.measurement.field.region"
+]
+```
+
+would result in the following Graphite -> Telegraf transformation.
+
+```
+cpu.usage.idle.us-west 100
+=> cpu_usage,region=us-west idle=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.us-west 100
+=> cpu_load,region=us-west 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.us-west 100
+=> cpu_usage,region=us-west,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. This can be "json", "influx" or "graphite" (line-protocol)
+  ## 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
+  ## 3. filter + template with field key
+  ## 4. default template
+  templates = [
+    "*.app env.service.resource.measurement",
+    "stats.* .host.measurement* region=us-west,agent=sensu",
+    "stats2.* .host.measurement.field",

+# Telegraf Output Data Formats
+
+Telegraf metrics, like InfluxDB

+
+For Telegraf outputs that write textual data (such as `kafka`, `mqtt`, and `file`),

+[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

+config option, for example, in the `file` output plugin:
+

+[[outputs.file]]
+  ## Files to write to, "stdout" is a specially handled file.

+  data_format = "influx"
+```
+
+## Graphite:
+
+The Graphite data format translates Telegraf metrics into _dot_ buckets.
+The format is:
+
+```
+[prefix].[host tag].[all tags (alphabetical)].[measurement name].[field name] value timestamp
+```
+
+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

-# Exec Plugin
-
-The exec plugin can execute arbitrary commands which output JSON. Then it flattens JSON and finds
-all numeric values, treating them as floats.
-
-For example, if you have a json-returning command called mycollector, you could
-setup the exec plugin with:
-
-```
-[[exec.commands]]
-command = "/usr/bin/mycollector --output=json"
-name = "mycollector"
-interval = 10
-```
-
-The name is used as a prefix for the measurements.
-
-The interval is used to determine how often a particular command should be run. Each
-time the exec plugin runs, it will only run a particular command if it has been at least
-`interval` seconds since the exec plugin last ran the command.
-
-
-# Sample
-
-Let's say that we have a command named "mycollector", which gives the following output:
-```json
-{
-    "a": 0.5,
-    "b": {
-        "c": "some text",
-        "d": 0.1,
-        "e": 5
-    }
-}
-```
-
-The collected metrics will be:
-```
-exec_mycollector_a value=0.5
-exec_mycollector_b_d value=0.1
-exec_mycollector_b_e value=5
-```

+

+# Sample Config:

+  ## servers to query
+  servers = ["8.8.8.8"] # required
+
+  ## Domains or subdomains to query. "." (root) is default
+  domains = ["."] # optional
+
+  ## Query record type. Posible values: A, AAAA, ANY, CNAME, MX,  NS, PTR, SOA, SPF, SRV, TXT. Default is "NS"
+  record_type = "A" # optional
+
+  ## Dns server port. 53 is default
+  port = 53 # optional
+
+  ## Query timeout in seconds. Default is 2 seconds
+  timeout = 2 # optional
+```
+
+For querying more than one record type make:
+
+```
+[[inputs.dns_query]]
+  domains = ["mjasion.pl"]
+  servers = ["8.8.8.8", "8.8.4.4"]
+  record_type = "A"

+# Docker Input Plugin
+
+The docker plugin uses the docker remote API to gather metrics on running
+docker containers. You can read Docker's documentation for their remote API
+[here](https://docs.docker.com/engine/reference/api/docker_remote_api_v1.20/#get-container-stats-based-on-resource-usage)
+
+The docker plugin uses the excellent
+[fsouza go-dockerclient](https://github.com/fsouza/go-dockerclient) library to
+gather stats. Documentation for the library can be found
+[here](https://godoc.org/github.com/fsouza/go-dockerclient) and documentation
+for the stat structure can be found
+[here](https://godoc.org/github.com/fsouza/go-dockerclient#Stats)
+
+### Configuration:
+
+```
+# Read metrics about docker containers
+[[inputs.docker]]
+  # Docker Endpoint
+  #   To use TCP, set endpoint = "tcp://[ip]:[port]"
+  #   To use environment variables (ie, docker-machine), set endpoint = "ENV"
+  endpoint = "unix:///var/run/docker.sock"
+  # Only collect metrics for these containers, collect all if empty
+  container_names = []
+```
+
+### Measurements & Fields:
+
+Every effort was made to preserve the names based on the JSON response from the
+docker API.
+
+Note that the docker_cpu metric may appear multiple times per collection, based
+on the availability of per-cpu stats on your system.

+# Dovecot Input Plugin
+
+The dovecot plugin uses the dovecot Stats protocol to gather metrics on configured
+domains. You can read Dovecot's documentation
+[here](http://wiki2.dovecot.org/Statistics)
+
+
+### Configuration:
+
+```
+# Read metrics about dovecot servers
+[[inputs.dovecot]]
+  # Dovecot servers
+  #  specify dovecot servers via an address:port list
+  #  e.g.
+  #    localhost:24242
+  #
+  # If no servers are specified, then localhost is used as the host.
+  servers = ["localhost:24242"]
+  # Only collect metrics for these domains, collect all if empty
+  domains = []
+```
+
+
+### Tags:
+	server: hostname
+	domain: domain name
+
+
+### Fields:
+
+	reset_timestamp        time.Time
+	last_update            time.Time

+# Exec Input Plugin
+
+The exec plugin can execute arbitrary commands which output:
+
+* JSON
+* InfluxDB [line-protocol](https://docs.influxdata.com/influxdb/v0.9/write_protocols/line/)
+* Graphite [graphite-protocol](http://graphite.readthedocs.org/en/latest/feeding-carbon.html)
+
+> Graphite understands messages with this format:
+
+> ```
+metric_path value timestamp\n
+```
+
+> __metric_path__ is the metric namespace that you want to populate.
+
+> __value__ is the value that you want to assign to the metric at this time.
+
+> __timestamp__ is the unix epoch time.
+
+
+If using JSON, only numeric values are parsed and turned into floats. Booleans
+and strings will be ignored.
+
+### Configuration
+
+```
+# Read flattened metrics from one or more commands that output JSON to stdout
+[[inputs.exec]]
+  # Shell/commands array
+  commands = ["/tmp/test.sh", "/tmp/test2.sh"]
+
+  # Data format to consume. This can be "json", "influx" or "graphite" (line-protocol)
+  # NOTE json only reads numerical measurements, strings and booleans are ignored.
+  data_format = "json"
+
+  # measurement name suffix (for separating different commands)
+  name_suffix = "_mycollector"
+
+  ## Below configuration will be used for data_format = "graphite", can be ignored for other data_format
+  ## If matching multiple measurement files, 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.  The can be only one default template.
+  ## Templates support below format:
+  ## 1. filter + template
+  ## 2. filter + template + extra tag
+  ## 3. filter + template with field key
+  ## 4. default template
+  #templates = [
+  #  "*.app env.service.resource.measurement",
+  #  "stats.* .host.measurement* region=us-west,agent=sensu",
+  #  "stats2.* .host.measurement.field",
+  #  "measurement*"
+  #]
+```
+
+Other options for modifying the measurement names are:
+
+```
+name_prefix = "prefix_"
+```
+
+### Example 1
+
+Let's say that we have the above configuration, and mycollector outputs the
+following JSON:
+
+```json
+{
+    "a": 0.5,
+    "b": {
+        "c": 0.1,
+        "d": 5
+    }
+}
+```
+
+The collected metrics will be stored as fields under the measurement
+"exec_mycollector":
+
+```
+exec_mycollector a=0.5,b_c=0.1,b_d=5 1452815002357578567
+```
+
+### Example 2
+
+Now let's say we have the following configuration:
+
+```
+[[inputs.exec]]
+  # Shell/commands array
+  # compatible with old version
+  # we can still use the old command configuration
+  # command = "/usr/bin/line_protocol_collector"
+  commands = ["/usr/bin/line_protocol_collector","/tmp/test2.sh"]
+
+  # Data format to consume. This can be "json" or "influx" (line-protocol)
+  # NOTE json only reads numerical measurements, strings and booleans are ignored.
+  data_format = "influx"
+```
+
+And line_protocol_collector outputs the following line protocol:
+
+```
+cpu,cpu=cpu0,host=foo,datacenter=us-east usage_idle=99,usage_busy=1
+cpu,cpu=cpu1,host=foo,datacenter=us-east usage_idle=99,usage_busy=1
+cpu,cpu=cpu2,host=foo,datacenter=us-east usage_idle=99,usage_busy=1
+cpu,cpu=cpu3,host=foo,datacenter=us-east usage_idle=99,usage_busy=1
+cpu,cpu=cpu4,host=foo,datacenter=us-east usage_idle=99,usage_busy=1
+cpu,cpu=cpu5,host=foo,datacenter=us-east usage_idle=99,usage_busy=1
+cpu,cpu=cpu6,host=foo,datacenter=us-east usage_idle=99,usage_busy=1
+```
+
+You will get data in InfluxDB exactly as it is defined above,
+tags are cpu=cpuN, host=foo, and datacenter=us-east with fields usage_idle
+and usage_busy. They will receive a timestamp at collection time.
+
+
+### Example 3
+
+We can also change the data_format to "graphite" to use the metrics collecting scripts such as (compatible with graphite):
+
+* Nagios [Mertics Plugins] (https://exchange.nagios.org/directory/Plugins)
+* Sensu [Mertics Plugins] (https://github.com/sensu-plugins)
+
+#### Configuration
+```
+# Read flattened metrics from one or more commands that output JSON to stdout
+[[inputs.exec]]
+  # Shell/commands array
+  commands = ["/tmp/test.sh","/tmp/test2.sh"]
+
+  # Data format to consume. This can be "json", "influx" or "graphite" (line-protocol)
+  # NOTE json only reads numerical measurements, strings and booleans are ignored.
+  data_format = "graphite"
+
+  # measurement name suffix (for separating different commands)
+  name_suffix = "_mycollector"
+
+  ## Below configuration will be used for data_format = "graphite", can be ignored for other data_format
+  ## If matching multiple measurement files, 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.  The can be only one default template.
+  ## Templates support below format:
+  ## 1. filter + template
+  ## 2. filter + template + extra tag
+  ## 3. filter + template with field key
+  ## 4. default template
+  templates = [
+    "*.app env.service.resource.measurement",
+    "stats.* .host.measurement* region=us-west,agent=sensu",
+    "stats2.* .host.measurement.field",
+    "measurement*"
+  ]
+```
+
+And test.sh/test2.sh will output:
+
+```
+sensu.metric.net.server0.eth0.rx_packets 461295119435 1444234982
+sensu.metric.net.server0.eth0.tx_bytes 1093086493388480 1444234982
+sensu.metric.net.server0.eth0.rx_bytes 1015633926034834 1444234982
+sensu.metric.net.server0.eth0.tx_errors 0 1444234982
+sensu.metric.net.server0.eth0.rx_errors 0 1444234982
+sensu.metric.net.server0.eth0.tx_dropped 0 1444234982
+sensu.metric.net.server0.eth0.rx_dropped 0 1444234982
+```
+
+The templates configuration will be used to parse the graphite metrics to support influxdb/opentsdb tagging store engines.

+# github_webhooks
+
+This is a Telegraf service plugin that listens for events kicked off by Github's Webhooks service and persists data from them into configured outputs. To set up the listener first generate the proper configuration:
+```sh
+$ telegraf -sample-config -input-filter github_webhooks -output-filter influxdb > config.conf.new
+```
+Change the config file to point to the InfluxDB server you are using and adjust the settings to match your environment. Once that is complete:
+```sh
+$ cp config.conf.new /etc/telegraf/telegraf.conf
+$ sudo service telegraf start
+```
+Once the server is running you should configure your Organization's Webhooks to point at the `github_webhooks` service. To do this go to `github.com/{my_organization}` and click `Settings > Webhooks > Add webhook`. In the resulting menu set `Payload URL` to `http://<my_ip>:1618`, `Content type` to `application/json` and under the section `Which events would you like to trigger this webhook?` select 'Send me <b>everything</b>'. By default all of the events will write to the `github_webhooks` measurement, this is configurable by setting the `measurement_name` in the config file.
+
+## Events
+
+The titles of the following sections are links to the full payloads and details for each event. The body contains what information from the event is persisted. The format is as follows:
+```
+# TAGS
+* 'tagKey' = `tagValue` type
+# FIELDS 
+* 'fieldKey' = `fieldValue` type
+```
+The tag values and field values show the place on the incoming JSON object where the data is sourced from.
