## v0.10.1 [unreleased]
### Release Notes:
- 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`)

# Telegraf Configuration
## Generating a Configuration File
A default Telegraf config file can be generated using the `-sample-config` flag,
like this: `telegraf -sample-config`
To generate a file with specific inputs and outputs, you can use the
`-input-filter` and `-output-filter` flags, like this:
`telegraf -sample-config -input-filter cpu:mem:net:swap -output-filter influxdb:kafka`
## Telegraf Agent Configuration
Telegraf has a few options you can configure under the `agent` section of the
config.
* **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.
## Input 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*"]
```
## 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 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"]
```

## Plugins
## Adding a dependency
This section is for developers who want to create new collection plugins.
Assuming you can already build the project:
1. `go get github.com/sparrc/gdm`
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 `inputs.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
### Input interface
```go
type Plugin interface {
type Input interface {
SampleConfig() string
Description() string
Gather(Accumulator) error
@ -52,52 +65,32 @@ type Accumulator interface {
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 {
"pid": fmt.Sprintf("%d", process.Pid),
}
acc.Add("cpu", process.CPUTime, tags, time.Now())
acc.Add("memory", process.MemoryBytes, tags, time.Now())
}
}
```

## Service Input Plugins
This section is for developers who want to create new "service" collection
plugins. A service plugin differs from a regular plugin in that it operates
inputs. A service plugin differs from a regular plugin in that it operates
a background service while Telegraf is running. One example would be the `statsd`
plugin, which operates a statsd server.

* An output must conform to the `outputs.Output` interface.
* Outputs should call `outputs.Add` in their `init` function to register themselves.
See below for a quick example.
* To be available within Telegraf itself, plugins must add themselves to the

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

### Version 0.3.0 Beta
Version 0.3.0 will introduce many new breaking changes to Telegraf. For starters,
plugin measurements will be aggregated into fields. This means that there will no
longer be a `cpu_usage_idle` measurement, there will be a `cpu` measurement with
a `usage_idle` field.
There will also be config file changes, meaning that your 0.2.x Telegraf config
files will no longer work properly. It is recommended that you use the
`-sample-config` flag to generate a new config file to see what the changes are.
You can also read the
[0.3.0 configuration guide](https://github.com/influxdb/telegraf/blob/0.3.0/CONFIGURATION.md)
to see some of the new features and options available.
You can read more about the justifications for the aggregated measurements
[here](https://github.com/influxdb/telegraf/issues/152), and a more detailed
breakdown of the work [here](https://github.com/influxdb/telegraf/pull/437).
Once we're closer to a full release, there will be a detailed blog post
explaining all the changes.

if you don't have it already. You also must build with golang version 1.5+.
1. [Install Go](https://golang.org/doc/install)
2. [Setup your GOPATH](https://golang.org/doc/code.html#GOPATH)
3. Run `go get github.com/influxdb/telegraf`
4. Run `cd $GOPATH/src/github.com/influxdb/telegraf`
3. Run `go get github.com/influxdata/telegraf`
4. Run `cd $GOPATH/src/github.com/influxdata/telegraf`
5. Run `make`
### 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

## 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>`.

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

Usage:
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:
- device

# 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:
```
[[inputs.exec]]
command = "/usr/bin/mycollector --output=json"
name_suffix = "_mycollector"
interval = "10s"
```
The name suffix is appended to exec as "exec_name_suffix" to identify the input stream.
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 with the name_suffix "_mycollector", which gives the following output:
```json
{
"a": 0.5,
"b": {
"c": 0.1,
"d": 5
}
}
```
The collected metrics will be stored as field values under the same measurement "exec_mycollector":
```
exec_mycollector a=0.5,b_c=0.1,b_d=5 1452815002357578567
```
Other options for modifying the measurement names are:
```
name_override = "newname"
name_prefix = "prefix_"
```

# Path of passenger-status.
#
# Plugin gather metric via parsing XML output of passenger-status
# More information about the tool:
# https://www.phusionpassenger.com/library/admin/apache/overall_status_report.html

#
# If no path is specified, then the plugin simply execute passenger-status
# hopefully it can be found in your PATH
command = "passenger-status -v --show=xml"
```
When run with:
```
./telegraf -config telegraf.conf -test -input-filter passenger
```
It produces:

# Note
You have to ensure that you can run the `passenger-status` command under
telegraf user. Depend on how you install and configure passenger, this
maybe an issue for you. If you are using passenger standlone, or compile
yourself, it is straight forward. However, if you are using gem and
`rvm`, it maybe harder to get this right.
Such as with `rvm`, you can use this command:
```
~/.rvm/bin/rvm default do passenger-status -v --show=xml
```
You can use `&` and `;` in the shell command to run comlicated shell command
in order to get the passenger-status such as load the rvm shell, source the
path
```
command = "source .rvm/scripts/rvm && passenger-status -v --show=xml"
```
Anyway, just ensure that you can run the command under `telegraf` user, and it
has to produce XML output.

# /var/run/php5-fpm.sock
# - http: the URL has to start with http:// or https://
# - fcgi: the URL has to start with fcgi:// or cgi://, and socket port must present
#
# If no servers are specified, then default to 127.0.0.1/server-status
urls = ["http://localhost/status", "10.0.0.12:/var/run/php5-fpm-www2.sock", "fcgi://10.0.0.12:9000/status"]
```
When run with:
```
./telegraf -config telegraf.conf -input-filter phpfpm -test
```
It produces:
```
* Plugin: phpfpm, Collection 1
> phpfpm,pool=www accepted_conn=13i,active_processes=2i,idle_processes=1i,listen_queue=0i,listen_queue_len=0i,max_active_processes=2i,max_children_reached=0i,max_listen_queue=0i,slow_requests=0i,total_processes=3i 1453011293083331187

```
## Note
When using `unixsocket`, you have to ensure that telegraf runs on same
host, and socket path is accessible to telegraf user.
