APC Transfer Switch to Nagios


#1

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 :roll:

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:

#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 '^\-|^\+' --- /tmp/apc1 2010-04-07 10:39:49.000000000 +0300 +++ /tmp/apc2 2010-04-07 10:41:59.000000000 +0300 -DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (5331955) 14:48:39.55 +DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (5344955) 14:50:49.55 -IF-MIB::ifInOctets.2 = Counter32: 1864540 +IF-MIB::ifInOctets.2 = Counter32: 1888174 -IF-MIB::ifInUcastPkts.2 = Counter32: 4925 +IF-MIB::ifInUcastPkts.2 = Counter32: 5176 -IF-MIB::ifInNUcastPkts.2 = Counter32: 11308 +IF-MIB::ifInNUcastPkts.2 = Counter32: 11314 -IF-MIB::ifOutOctets.2 = Counter32: 625738 +IF-MIB::ifOutOctets.2 = Counter32: 650566 -IF-MIB::ifOutUcastPkts.2 = Counter32: 4816 +IF-MIB::ifOutUcastPkts.2 = Counter32: 5067 -IP-MIB::ipInReceives.0 = Counter32: 16162 +IP-MIB::ipInReceives.0 = Counter32: 16419 -IP-MIB::ipInDelivers.0 = Counter32: 15511 -IP-MIB::ipOutRequests.0 = Counter32: 4943 +IP-MIB::ipInDelivers.0 = Counter32: 15768 +IP-MIB::ipOutRequests.0 = Counter32: 5194 -IP-MIB::icmpInMsgs.0 = Counter32: 207 +IP-MIB::icmpInMsgs.0 = Counter32: 210 -IP-MIB::icmpInEchos.0 = Counter32: 9 -IP-MIB::icmpInEchoReps.0 = Counter32: 197 +IP-MIB::icmpInEchos.0 = Counter32: 11 +IP-MIB::icmpInEchoReps.0 = Counter32: 198 -IP-MIB::icmpOutMsgs.0 = Counter32: 206 +IP-MIB::icmpOutMsgs.0 = Counter32: 209 -IP-MIB::icmpOutEchos.0 = Counter32: 197 -IP-MIB::icmpOutEchoReps.0 = Counter32: 9 +IP-MIB::icmpOutEchos.0 = Counter32: 198 +IP-MIB::icmpOutEchoReps.0 = Counter32: 11 -UDP-MIB::udpInDatagrams.0 = Counter32: 4547 -UDP-MIB::udpNoPorts.0 = Counter32: 10643 +UDP-MIB::udpInDatagrams.0 = Counter32: 4795 +UDP-MIB::udpNoPorts.0 = Counter32: 10649 -UDP-MIB::udpOutDatagrams.0 = Counter32: 4652 +UDP-MIB::udpOutDatagrams.0 = Counter32: 4900 -SNMPv2-MIB::snmpInPkts.0 = Counter32: 4562 -SNMPv2-MIB::snmpOutPkts.0 = Counter32: 4562 +SNMPv2-MIB::snmpInPkts.0 = Counter32: 4810 +SNMPv2-MIB::snmpOutPkts.0 = Counter32: 4810 -SNMPv2-MIB::snmpInTotalReqVars.0 = Counter32: 4572 +SNMPv2-MIB::snmpInTotalReqVars.0 = Counter32: 4820 -SNMPv2-MIB::snmpInGetNexts.0 = Counter32: 4576 +SNMPv2-MIB::snmpInGetNexts.0 = Counter32: 4824 -SNMPv2-MIB::snmpOutGetResponses.0 = Counter32: 4586 -SNMPv2-MIB::snmpOutTraps.0 = Counter32: 2682 +SNMPv2-MIB::snmpOutGetResponses.0 = Counter32: 4834 +SNMPv2-MIB::snmpOutTraps.0 = Counter32: 2688 martin@home:~>

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 in order to finally add this device to Nagios? :roll:
