Collectd SOP

Collectd ( https://collectd.org/ ) is a client/server setup that gathers system information from clients and allows the server to display that information over various time periods.

Our server instance runs on log01.rdu3.fedoraproject.org and most other servers run clients that connect to the server and provide it with data.

The collectd roles configure collectd on the various machines:

collectd/base - This is the base client role for most servers.
collectd/bind - dns servers role

Restarting

collectd runs as a normal systemd service, so you can: systemctl restart collectd restart it.

Removing old hosts

Collectd keeps information around until it’s deleted, so you may need to sometime go remove data from a host or hosts thats no longer used. To do this:

  1. Login to log01

  2. cd /var/lib/collectd/rrd

  3. sudo rm -rf oldhostname

Bug reporting

Collectd is in Fedora/EPEL and we use their packages, so report bugs to bugzilla.redhat.com.
