Set temperature alarms and warnings?

[PenguinJeff]

One of my hosts is complaining about one sensor being outside a range.

I would like to change the range for than sensor.

I first turned off the machine and looked for any dust buildup or anything that had changed as I never had issues with this before.

The only difference is I upgraded from ESXI 5.5 to ESXI 6.5

I can disable all hardware temperature sensors but I would rather just change the range for warnings or alarms for that one sensor.

Or maybe just disable the one sensor.

I'm guessing the older version didn't even have the sensor readings for the complaining sensor.

I am not seeing any good information on how to do what I would like.

If I go to the host with the sensor

go to its monitor tab

select hardware status

Select sensors

I can see an alert under temperature

If I expand temperature I can see it complaining about "System Board 1 IOH Temp" at 49C on my other two it is at 41C

If I could tweak the sensor settings for warnings and alerts I would like to.

OK I saw from another thread that it is set by the computer so I am looking into the settings of the bios hopefully I can see the settings in there someplace.

Hello.

We may be having same issue.

We'd like to change CPU temperature warning threshold that shows in /var/log/messages .

It would be nice if you could share your findings with us.

Thank you.

So I have seen this error a couple of times.

On all the occasions the host was not compatible with ESXi 6.5.

Make sure you test that on this link https://www.vmware.com/resources/compatibility/search.php

Since its not tested hardware the results can be inconsistent.
