Problem with SNMP monitoring...

[mrjavum]

APC Symmetra PX has such OIDs (upsPhaseInputVoltage):

$ snmpwalk -c public -v2c IP enterprises.318.1.1.1.9.2.3.1.3
SNMPv2-SMI::enterprises.318.1.1.1.9.2.3.1.3.2.1 = INTEGER: 231
SNMPv2-SMI::enterprises.318.1.1.1.9.2.3.1.3.2.2 = INTEGER: 228
SNMPv2-SMI::enterprises.318.1.1.1.9.2.3.1.3.2.3 = INTEGER: 228
SNMPv2-SMI::enterprises.318.1.1.1.9.2.3.1.3.3.1 = INTEGER: 231
SNMPv2-SMI::enterprises.318.1.1.1.9.2.3.1.3.3.2 = INTEGER: 227
SNMPv2-SMI::enterprises.318.1.1.1.9.2.3.1.3.3.3 = INTEGER: 228

But how to get only one value?
Trying snmpget:

$ snmpget -c public -v2c IP enterprises.318.1.1.1.9.2.3.1.3.2.1
SNMPv2-SMI::enterprises.318.1.1.1.9.2.3.1.3.2.1 = INTEGER: -1

but no luck And Zabbix gets the same value...

Is there any another way to monitor this values in Zabbix?

Thanks in advance!

now that looks like a bug in ups firmware (and i have actually seen similar bugs in upses from other vendors).

i'd suggest first checking available fw updates, if they don't solve the problem - contact apc.

if, and only if, they are not fixing this bug, you can try using external check and getting value with snmpgetnext for the previous record.

overall apc have been quite decent with providing access and tools (think apcupsd), so i'd be surprised if they won't fix such a bug. if they don't, post about it here and email their sales/pr contacts with a link =)

Big thanks!

It is magic!
I updated it to latest firmware and now it works!
