How to monitor temperature in fortiswitches through snmp?

[JohnnyAIM]

Hello Forti community,

I am trying to monitor the temperature of our Forti Switches through snmp.

I get difficulty with some models. 

I am using the ENTITY-SENSOR-MIB (1.3.6.1.2.1.99)

I check the temperature with oid .1.3.6.1.2.1.99.1.1.1.4

In the model 448E-P, I get values 43 and 40.

The sensor precision is set at 1 in the oid .1.3.6.1.2.1.99.1.1.1.3

Meaning that it should be 4.3 and 4.0 degrees Celcius.

In the model 148F-F, I get values 37 and 50

The sensor precision is set at 0 in the oid .1.3.6.1.2.1.99.1.1.1.3

Meaning that it should be 37 and 50 degrees Celcius.

I am a bit confuse on how to check the temperature of the fortiswitches through snmp.

Anyone has a successful setup working?

Is the temperature indeed in celcius?

Is the sensor precision used for calculating the switch temperature?

Thank you for your help

Ok, I dig a bit more and it seems to be firmware related and not model related.

It seems to be a bug in firmware v7.2.5

All the working one are running v7.4.3

Thank you all
