Note Software involved: FreeNAS 9.2.0 OMD 1.10 (check_mk 1.2.2p3) FreeNAS is great, and the web interface makes it easy and simple to understand my NAS's overall structure. However, my favored method of monitoring in my homelab is OMD with Check_mk, while FreeNAS prefers a self-contained collectd solution. We're in luck however, in that FreeNAS is heavily based on FreeBSD, which check_mk happens to have a plugin for, so it shouldn't be too hard to set things up the way I like them.
