(This should be the actual temperature and 45C seems about what I would expect)

That's encouraging. I notice that the configuration you originally posted referred
to a different pair of OIDs:

Target[10.100.214.3]: 1.3.6.1.2.1.2.2.1.14.1&1.3.6.1.2.1.2.2.1.20.1:[email protected]

and that the one in your latest post uses the same OIDs as you used with snmpwalk.

I wonder whether you are still seeing the -1 values in the log file since making
this correction.

If I recall correctly (and I'm not sure that I do), loading the MIB is for convenience rather than function; it allows reference to an OID by name rather than by dotted tuple.
If I'm mistaken, I hope someone else on the list will put me right.

In any case, if you wish to load non-default MIBs, you just need to refer to the relevant files in the global 'LoadMIBs' option. I'm not familiar with Windows, so can't suggest where the 'natural' place in your file hierarchy for these files
might be.

Each of the graphs is generated independently and scaled according to the range of values actually present; the MaxBytes parameter isn't taken into account.
