wherein missing performance counters caused it to return
early from the loop, instead of ignoring missing in
default configuration mode.

9c0d14bb60 Create public models for telegraf metrics, accumlator, plugins
This will basically make the root directory a place for storing the
major telegraf interfaces, which will make telegraf's godoc looks quite
a bit nicer. And make it easier for contributors to lookup the few data
types that they actually care about.

40d0da404e Change configuration package to influxdata/config
We are unifying the way that we handle configuration across the products
into the influxdata/config package. This provides the same API as
naoina/toml that was used previously, but provides some additional
features such as support for documenting generated TOML configs as well
as support for handling default options. This replaces all usage of
naoina/toml with influxdata/config.

839651fadb Change default statsd packet size to 1500, make configurable
Also modifying the internal UDP listener/parser code to make it able to
handle higher load. The udp listener will no longer do any parsing or
string conversion. It will simply read UDP packets as bytes and put them
into a channel. The parser thread will now deal with splitting the UDP
metrics into separated strings.

This could probably be made even better by leaving everything as byte
arrays.

With the advent of Kafka 0.9.0+ it is possible to set up TLS client
certificate based authentication to limit access to Kafka.

Four new configuration variables are specified for setting up the
authentication. If they're not set the behavior stays the same as
before the change.

## v0.10.3 [unreleased]
### Release Notes
### Features
### Bugfixes
## v0.10.2 [2016-02-04]
### 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
doing the opposite of what it claimed to do (yikes). It's been replaced by
`insecure_skip_verify`
### Features
- [#575](https://github.com/influxdata/telegraf/pull/575): Support for collecting Windows Performance Counters. Thanks @TheFlyingCorpse!
- [#564](https://github.com/influxdata/telegraf/issues/564): features for plugin writing simplification. Internal metric data type.
- [#603](https://github.com/influxdata/telegraf/pull/603): Aggregate statsd timing measurements into fields. Thanks @marcinbunsch!

## 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`)

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`
## `[tags]` Configuration
Global tags can be specific in the `[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:
* **pass**: 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.
* **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 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
[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: pass and drop
```toml
# Drop all metrics for guest & steal CPU usage
[[inputs.cpu]]
percpu = false
totalcpu = true
drop = ["usage_guest", "usage_steal"]
# Only store inode related metrics for disks
[[inputs.disk]]
pass = ["inodes*"]
```
#### 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
(pass, drop, tagpass, tagdrop)
```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"]
```

## 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
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.

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`.
* **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`.
* **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 {

# Telegraf [![Circle CI](https://circleci.com/gh/influxdata/telegraf.svg?style=svg)](https://circleci.com/gh/influxdata/telegraf)
Telegraf is an agent written in Go for collecting metrics from the system it's
running on, or from other services, and writing them into InfluxDB.
running on, or from other services, and writing them into InfluxDB or other
[outputs](https://github.com/influxdata/telegraf#supported-output-plugins).
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).
We'll eagerly accept pull requests for new plugins and will manage the set of
plugins that Telegraf supports. See the
[contributing guide](CONTRIBUTING.md) for instructions on
writing new plugins.
New input and output plugins are designed to be easy to contribute,

### How to use it:
## How to use it:
* 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.
```console
$ telegraf -help
Telegraf, The plugin-driven server agent for collecting and reporting metrics.
## 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:
## 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 5 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 glob match against metric names
and if it matches, the metric is emitted.
* **drop**: The inverse of pass, if a metric name matches, it is not emitted.
* **tagpass**: tag names and arrays of strings that are used to filter metrics by the current plugin. Each string in the array is tested as a glob match against
the tag name, and if it matches the metric is emitted.
* **tagdrop**: The inverse of tagpass. If a tag matches, the metric is not emitted.
This is tested on metrics 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.
# generate a telegraf config file:
telegraf -sample-config > telegraf.conf
### Plugin Configuration Examples
# generate config with only cpu input & influxdb output plugins defined
telegraf -sample-config -input-filter cpu -output-filter influxdb
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
measurements which begin with `cpu_time`.
# run a single telegraf collection, outputing metrics to stdout
telegraf -config telegraf.conf -test
```toml
[tags]
dc = "denver-1"
# run telegraf with all plugins defined in config file
telegraf -config telegraf.conf
[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
drop = ["cpu_time*"]
# run telegraf, enabling the cpu & memory input, and influxdb output plugins
telegraf -config telegraf.conf -input-filter cpu:mem -output-filter influxdb
```
Below is how to configure `tagpass` and `tagdrop` parameters
## Configuration
```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" ]
See the [configuration guide](CONFIGURATION.md) for a rundown of the more advanced
configuration options.
[[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*" ]
```
## Supported Input Plugins
Below is how to configure `pass` and `drop` parameters
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`.
```toml
# Drop all metrics for guest CPU usage
[[plugins.cpu]]
drop = [ "cpu_usage_guest" ]
# Only store inode related metrics for disks
[[plugins.disk]]
pass = [ "disk_inodes*" ]
```
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*"]
```
## Supported Plugins
**You can view usage instructions for each plugin by running**
`telegraf -usage <pluginname>`.

## Supported Service Plugins
Telegraf can collect metrics via the following services:
Telegraf can also collect metrics via the following service plugins:
* statsd
* kafka_consumer
* github_webhooks
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.
## Output options
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"]
```

telegraf <flags>
The flags are:

-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

# 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
```

# 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.

- io_serviced_recursive_async
- io_serviced_recursive_read
- io_serviced_recursive_sync
- io_serviced_recursive_total
- io_serviced_recursive_write
### Tags:
- All stats have the following tags:
- cont_id (container ID)
- cont_image (container image)
- cont_name (container name)
- docker_cpu specific:
- cpu
- docker_net specific:
- network
- docker_blkio specific:

# Exec Input Plugin
The exec plugin can execute arbitrary commands which output JSON or
InfluxDB [line-protocol](https://docs.influxdata.com/influxdb/v0.9/write_protocols/line/).
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]]
# the command to run
command = "/usr/bin/mycollector --foo=bar"
# 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 = "json"
# measurement name suffix (for separating different commands)
name_suffix = "_mycollector"
```
Other options for modifying the measurement names are:
```
name_override = "measurement_name"
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]]
# the command to run
command = "/usr/bin/line_protocol_collector"
# 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.

# 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.
