= 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.phx2.fedoraproject.org and most other
servers run clients that connect to the server and provide it with data.

== Restarting

collectd runs as a normal systemd or sysvinit service, so you can:
systemctl restart collectd or service collectd restart to 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:

[arabic]
. Login to log01
. `cd /var/lib/collectd/rrd`
. `sudo rm -rf oldhostname`

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