[nflug] Nagios and old Dell boxes

[Robert Meyer]

This is one of the big, honking whole-room UPS systems.  It has an add-on card that does SNMP (and not very well).  You can use SNMP to get some information about temperatures and voltages but outage and brown-out condtions are only reported via SNMP traps.  The trap is initiated by the UPS and someone has to be listening for the trap when it comes in.  It's a big Liebert/Emerson UPS and has about $2000 worth of batteries tied to it.

Cheers!

Bob

As far as the UPS goes, if you can get it to communicate with apcupsd, 
that will network monitor and notify via email or user account.
