This plugin, named mdevents, is responsible for gathering the events
from RAID arrays that were written to syslog by mdadm utility (which
is a user-space software for managing the RAIDs). Then, based on
configuration provided by user, plugin will decide whether to send the
collectd notification or not.
Mdevents needs the syslog and mdadm to be present on a platform that
collectd is launched.
