Anyone know how to get the current load (Amps or Watts) on an APC AP7802 through SNMP?

Can't believe the standard set of OIDS from APC don't get the most basic thing you want from a PDU - what's it drawing with respect to its maximum capacity?

Very frustrating.

It's not easy, and it depends if your PDU supports the rPDU2 part of APC's MIB.

If you have a look at the table at 1.3.6.1.4.1.318.1.1.26.8.3 there should be entry is column 5 called rPDU2BankStatusCurrent which gives "...the current draw, in tenths of Amps , of the load on the Rack PDU bank being queried". So you need to divide this figure by 10 to get Amps, and then compare to the maximum current draw which is given in 1.3.6.1.4.1.318.1.1.26.8.1 (r2PDUBankConfigTable), and in particular column 7 which gives "User-defined bank overload current threshold in Amps". You could also use column 6 which gives "User-defined near bank overload current warning threshold in Amps".

If you want to do alerting, you're looking at some custom SQL to do the comparisons!

Thanks for the reply on this.  I'll dig into it and see what I can come up with.  Was just hoping someone had already developed something like this (seems like an obvious need).
