## v0.10.1 [unreleased]
### 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.

# 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.
- docker_mem
- total_pgmafault
- cache

- total_inactive_file
- pgpgout

- 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

# Example output
Using this configuration:
```
[[inputs.passenger]]
# 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.
