Custom SNMP Formula Convert C to F


I'm new to IMC. I have a custom SNMP index to pull chassis temp for various devices and of course returns a Celsius reading. I'm attempting to create a formula to convert it to Fahrenheit but am having troubles.

I copied the existing monitor that is working and used the following formula, but it doesn't work. I've also tried enclosing the OIDs in their own parentheses and a few other variations.


What am I doing wrong?

Ah, life would be a lot easier if everyone used standard units, wouldn't it?

I think the problem here is that IMC is treating 1.8 as an OID value. If that is the case, you'll see IMC attempting to poll the test device for a couple of OIDs, including the temperature OID, and 1.8. The device will of course respond with noSuchObject.

You might need to try doing something like Temp * 9/5 + 32.
