Temperature wrong on r7515. Grafana is showing CPU temp as inlet temp. #22

HI there,

This is a great dashboard -on my r7515 the temps section is messed up. Three temps show in iDrac:

CPU, Inlet Temp, and Exhaust Temp

In Grafana:

Inlet temp - is actually CPU temp.
exhaust temp - is actually inlet temp
CPU temp missing.

Could this be a SNMP MIBs issue?

Ok I swapped the entries for the the temps in the telegraf and it appears to have corrected the issue.

Unfortunately, it seems that Dell's iDRAC behavior is VERY picky about the order of OIDs and I have seen OIDs swap what they link to based on the very specific combination of hardware/generation someone has. Seems like poor design on Dell's part so not sure what can be done to fix that.
