how to monitor the modules from an APC UPS Symmetra?



There are some sensors available under the "Apc Ups.oidlib" SNMP library sensor but none of the options i see are related to individual modules or frames.

We have the need of this monitor because one of the modules recently failed and there was not other monitoring tool besides Symmetra and we would like to have all our monitoring for this into PRTG if possible.

Please advise.

This would likely be possible if you find the MIB for the specific device you are using. They will usually have more specific OIDs for monitoring that specific device and you could take that MIB and import it with the MIB Importer. Once you import the MIB into an OID library, you could create an SNMP library sensor with that library and see what is available from the device to monitor.

Thanks Greg,

We imported some files and the one we have in use for this device is the Powernet407 file, but when looking for a sensor to monitor modules, it only shows one.

However after adding any sensor the result is in integers and I don't know what the #'s mean.

How can I find this out?, or is there a particular recommendation to monitor modules on symmetra in a different way?, any other suggestions.

Can you please send over the MIBs that you imported into PRTG along with the OID that you are using for the custom sensor to [email protected]? What also might be helpful is to scan the device with the SNMP Tester and the OID library that you created and send that log over as well.
