Custom temperature sensor monitoring

If you run a "Custom OID" test using the OID in case via our SNMP Tester, what results do you get?

I am able to enter a custom OID and get a string value back, which I've then changed to float and it does start to graph. Why does the SNMP Library sensor type not work though and how would i go about getting it to show warning at a certain temperature level and fail at another temperature level?

In order to check on that, please run a "Scan OIDLIB" test via the SNMP Tester, using the OIDLIB in case. You can then either post the results here or forward us the same to [email protected]. If you do the latter, please also forward us the OIDLIB and refer to this thread.

I will certainly give that a shot. Does it require that I run it on the remote probe machine or on the PRTG server? Does it require that I somehow install MIBS on the remote probes as well?

Please run the Tester on the machine running the probe from which you want to monitor the device in case. Beyond the Tester you shouldn't need to install / apply anything else.

I completed the OIDLIB scan from the probe machine and it enumerated the values just great. How do we apply that to the SNMP Library plugin?

I'm afraid in that case we will need to have a look at the results and the OIDLIB in case. Could you please forward us the Scan OIDLIB results, as well as the OIDLIB to [email protected] and refer to this thread?

Actually, I think we're getting closer! I figured out that after a firmware update to one of the sensor devices, I'm now able to use the SNMP Library Sensor to get a list of possible values to return. On devices running the older firmware, they won't complete a OIDLIB scan. I'll work on updating them later. That said, when I use the SNMP Library sensor, it gives me a list, but when I add the sensors, everything shows up as ms. I'd like it to somehow show the name of the sensor and then the temperature value. How do I get it to do that?

That should be defined within the OIDLIB. Open the same with the MIB Importer and check the settings of the affected OIDs. Als, please check the channel settings of the sensors - and compare with what results from the OIDs in the OIDLIB scan. If they do match what you expect, we would require the OIDLIB scan and the OIDLIB file for analysis.
