I am tweaking icinga checks for my servers, one of the checks is monitoring CPU temperatures. Problem is that each CPU has different operating temperatures T_MAX etc. where it should actually show some alert.

In my case it's these CPU:

  • Intel(R) Xeon(R) CPU E3-1230 v6 @ 3.50GHz
  • Intel(R) Xeon(R) CPU E3-1220 v3 @ 3.10GHz
  • Intel(R) Xeon(R) CPU E3-1230 v5 @ 3.40GHz

I was looking at intel ARK website, which contains various parameters, but none of these specify optimal temperatures, or T_MAX

Is there any database that contains such information or any place where this can be looked up?

You can find what you're looking for in Intel's technical resources for your Xeon chips.

  • Find the section that pertains to your particular processor. In your case Intel® Xeon® Processor E3 Family
  • Find the subsection for each separate type: Intel® Xeon® processor E3-1200 v3 product family, Intel® Xeon® processor E3-1200 v5 product family, and Intel® Xeon® processor E3-1200 v6 product family.
  • Under Technical Documents, Open up the Datasheet, Volume 1. That's where the TJMax values are written under Junction Specifications along with a host of other useful information regarding thermals.

To speed things up, in chrome I used Find (Ctrl + F) and entered in °C. You can then easily find the sections containing thermal values.

  • I will expand your answer a bit, after searching in these documents I couldn't find precise value - it actually seems each single CPU is unique and has own TjMAX factory calibrated when testing, from intel datasheet: TjMAX is factory calibrated and is not user configurable. The default value is software visible in the TEMPERATURE_TARGET (0x1A2) MSR, bits [23:16] – Petr Mar 11 at 14:51
  • it would be interesting to know how to obtain that TEMPERATURE_TARGET (0x1A2) MSR, bits [23:16] via some software (preferably Linux) I have no idea, it's not in dmi dump – Petr Mar 11 at 14:53
