[TriLUG] Open source software to monitor hundreds of VMs

[Brantley West via TriLUG]

I use Observium.  It provides basic CPU/memory/storage metrics, up/down
status, alerts, and can be used as syslog server if you put enough
resources behind it.  The only drawback is that all your devices have to be
in DNS and SNMP (v2 or v3) needs to be running for useful stats.
