AVTECH IP temperature MIB Mystery

Hello !

The OIDs in the MIB Browser for the devices are listed as 1.3.6.1.4.1.20916.1.7.1.1.1.1 for {internal-tempc} (celsius senor 1) and ...20916.1.7.1.1.1.2 for {internal-tempf} (Farenheit sensor 2). I built a custom polller with a conversion to change both radial gauges to read Farenheit and the OID test and pulls data successfully.

I got the AVTech template from Thwack which pulls data on the two sensors for the AVTech devices because I wanted to set up an APM alert. I'm confused because the OIDs listed in the template are different from what is in my MIB browser, yet it still pulls the correct data. As a matter of fact, it turns out that the OIDs in the template seem to be correct because when I go to the device web UI to see the temperature readings they both reflect what the Thwack template pulls. I put the OIDs from the template into the fields when building a custom poller, but it keeps coming back with an "OID not supported" message....yet for some reason those OIDs pull data with no problem in the template. I also looked through the MIB browser for AVTech and couldn't find any OIDs listed that match the template.

Is it possible the MIB browser has the wrong OIDs for the device???

It's very unlikely that the MIB browser has the wrong OID for the device. What's more likely is that the vendor has exposed similar information through multiple OIDs. Using the latest version of the MIB database, which is downloadable through your customer portal, I was able to find all OIDs referenced in your post, as well as the AVTECH TemPageR 3E SAM template available here on thwack.

From your post above

internal-tempf - 1.3.6.1.4.1.20916.1.7.1.1.1.2

The internal temperature reading in Fahrenheit. Because the SNMP Protocol does not support floating point numbers , values are scaled by 100 and should be divided by 100 to get the actual value.

From the AVTECH TemPageR 3E template and your post above.

internal-tempc - 1.3.6.1.4.1.20916.1.7.1.1.1.1

The internal temperature reading in Celsius. Because the SNMP Protocol does not support floating point numbers , values are scaled by 100 and should be divided by 100 to get the actual value.

From the AVTECH TemPageR 3E template.

digital-sen1-1 - 1.3.6.1.4.1.20916.1.7.1.2.1.1

If this sensor is a Temperature or Temp/Humidity sensor , this value represents the current temperature in Celsius. If this sensor is a Digital Power Sensor , this value represents the Current reading in Amperage.

Thanks again for your help, I'll download that MIB database from the portal and update. I got my SCP (with the help of studying for my CCNA), but it still feels like I'm always learning new stuff with Solarwinds. (or discovering new problems)

As a side note - I've confirmed you did indeed pass your SCP and I've added the SCP badge to your profile.:)

Thanks for taking the time to post this info - I was setting up a few of these today and it was exactly what I was looking for. AVTECH doesn't seem to make their MIBs available via their website without login, thwack to the rescue!
