collectd is a daemon which collects system performance statistics periodically and provides mechanisms to store the values in a variety of ways, for example in RRD files.
This image allows you to run collectd in a completelly containerized environment
Run collectd with the default configuration:
docker run \
--privileged \
-v /proc:/mnt/proc:ro \
fr3nd/collectd
Run collectd with a custom configuration stored in /etc/collect
docker run \
--privileged \
-v /etc/collectd:/etc/collectd:ro \
-v /proc:/mnt/proc:ro \
fr3nd/collectd
Yes. Collectd needs access to the parent host's /proc filesystem to get statistics. It's possible to run collectd without passing the parent host's /proc filesystem without running the container as privileged, but the metrics would not be acurate.
