snmpwalk'ing APC Transfer Switch

[m4rtin]

I have an APC AP7723 Transfer Switch. It is a great piece of hardware, which supports monitoring over SNMP as well. However, I'm not able find correct OID's to ask

I know, that it's possible to poll for example selected power source, redundancy state, output voltages, output current etc. However, I did a fallowing test:

Code: Select all

#ATS load is 0.8A
martin@home:~> snmpwalk -c public -v 2c 192.168.1.101 > /tmp/apc1
#I increased ATS load to 2.2A
martin@home:~> snmpwalk -c public -v 2c 192.168.1.101 > /tmp/apc2
#diff between /tmp/apc1 and /tmp/apc2 should show this increase from 0.8A to 2.2A
martin@home:~> diff -u /tmp/apc1 /tmp/apc2 | grep -E '^\-|^\+'

As I understand, there are only network related differences present like counted packages of different protocols(ICMP, SNMP, etc). Any ideas how to poll more data(like output voltages and output current) from this APC Transfer Switch over SNMP using snmpwalk?

Maybe you can give a try to the user-generated apc templates:

http://forums.cacti.net/about7612.html

In the thread is also a discussion about OIDs.

This is little bit late, but because i searched answer for the same problem here is my solution for it.

You can browse the device's power information with snmpwalk by defining the starting node:

# snmpwalk -c public -v 1 192.168.0.4 1.3.6.1.4.1.318

And in the Zabbix there is working config for APC AP7722 and those OID:s will work with the 7723 also.
