How to check CPU temperature on i2x00 series device?

[Lapsio]

How can I query CPU temperature? I've read through BIG-IP mib files and tried snmpwalk but it seems that CPU temperature info is not available on this device. I'm getting only following info when querying "sysCpu" branch:

snmpwalk -On -c public -v 2c 127.0.0.1 sysCpu
.1.3.6.1.4.1.3375.2.1.3.6.1.0 = INTEGER: 0

And that's it. Querying sysCpuSensorTemperature or sysCpuTemperature returns error that there's no object available at this OID. I can only get sysChassisTemp but it's not really what I'm looking for.

I think cpu temperature information is available (at least should be I guess) since I'm getting TCTL-Delta temp high(crit) alerts in AOM. So I wanted to check out what's is exact value of temperature.

The sysCpu OID has been deprecated. Try probing sysCpuSensorTemperature instead.

Similarly, sysCpuSensorTemperature did not return any data
