Trying to monitor some TrippLite switched/metered vertical PDUs with PRTG using SNMP. I can't seem to find any MIB that would provide me with the output current.

Anyone have experiencing monitoring these TrippLite PDUs with SNMP? I've download both the TRIPPLITE-MIB and UPS-MIB from their website, but neither of these files contains an entry to current in amps.

EDIT:

  1. MIBS downloaded from here
  2. Running the following snmpwalk command snmpwalk -v2c -c tripplite 192.168.15.25 1.3.6.1.4.1.850.100.1.4 which is responding with SNMPv2-SMI::enterprises.850.100.1.4 = No Such Object available on this agent at this OID
  • Is tlUpsOutletCurrent 1.3.6.1.4.1.850.100.1.10.2.1.13 not in amps? – Ron Maupin Aug 27 '15 at 19:41

  • This is where I got one for a Tripp Lite: oidview.com/mibs/850/TRIPPLITE-MIB.html There are instructions on the page that include: To query a live agent with SNMP for objects in module TRIPPLITE-MIB, use OidView Network Management Tools or SNMP SNMP MIB Browser. – Ron Maupin Aug 27 '15 at 20:01

Assuming this is the MIB that you're referring to, I see the following table:

tlUpsOutputCircuitTable

With each row in the table being:

tlUpsOutputCircuitIndex     PositiveInteger,
tlUpsOutputCircuitStatus    INTEGER,
tlUpsOutputCircuitLoadCurrent   NonNegativeInteger

Presumably tlUpsOutputCircuitLoadCurrent would be what you want, and represents the amps in tenths?

EDIT: Try telling Net-SNMP where to load the MIBs from when you run snmpwalk. Assuming you've saved those MIB files to /home/ethan/.snmp/mibs you would do the following:

snmpwalk -M +/home/ethan/.snmp/mibs -m +TRIPPLITE-MIB -v2c -c 'tripplite' 192.168.15.25 tlUpsOutputCircuitTable

If that still returns an error, the next step would be to just run a bulkwalk on the unit to see what OIDs are available, as the SNMP agent on the device may not export everything that's available in TRIPPLITE-MIB.

snmpbulkwalk -M +/home/ethan/.snmp/mibs -m +TRIPPLITE-MIB -v2c -c 'tripplite' 192.168.15.25

  • That's whats confusing me. When I snmpwalk on the device I don't even see those OIDs showing up. According to this page I should be able to use OID 1.3.6.1.4.1.850.100.1.4.7.1.3 to get load current, but I'm getting 'No Such Object available on this agent at this OID` – Ethan H.

  • Can you edit the original question with the following information: 1) Where are you keeping your MIBs and 2) How you're calling the snmpwalk command? – John Jensen Aug 27 '15 at 19:50
  • I've edited my answer. – John Jensen Aug 27 '15 at 20:10

    I would run the snmpbulkwalk then to see what objects out of TRIPPLITE-MIB are exported from your PDU. – John Jensen Aug 27 '15 at 20:17

    That helped, now I'm seeing some useful data. UPS-MIB::upsOutputCurrent.1 = INTEGER: 40 0.1 RMS Amp. Looks like this is 4 amps. Thanks for the help! – Ethan H. Aug 27 '15 at 20:21
