Dockerstats

Dockerstats is a simple docker container for collecting metrics from the Docker Stats API and sending them elsewhere. It supports adapters for configuring where you want metrics to be sent. It's heavily inspired by logspout and is roughly similar to cadvisor but simpler.

Currently, the following adapters are provided:

  • Log: An adapter that logs stats to stdout. This adapter can be useful if you're already using something like logspout to collect logs from containers. The format can be configured via the STAT_TEMPLATE environment variable. The default template is a template that will log stats in l2met format. Here's an example set of metrics with the default template.
  • Statsd: TODO
  • Librato: TODO

Usage

Simply run the container and mount the docker socket:

$ docker run --name="dockerstats" \
    --volume=/var/run/docker.sock:/tmp/docker.sock \
    remind101/dockerstats

Metrics
