Multiple CPU cores not used on 8250 appliance

ruben.omez — Fri, 21 Feb 2020 14:54:16 GMT

Hi all,

Does anyone knows why 2 of my 24 cores aren't used by the appliance?

We are running version 6.1.0.4.

See attached screenshot.

Thanks.

I don't see any documented bug on either 6.1.0.4 or 6.1.0.5 related to that symptom.

Either it is a false reading by the GUI (bug) or it is by design (feature). You might be able to verify from the cli using a Linux utility like mpstat.

If that doesn't help, I'd suggest opening a TAC case if you want to know for certain.

Hello Marvin,

Thank you for your assistance! I'll verify the cores with the tools you provided. If it seems not to be a cosmetical issue, I'll log a TAC case.

Hello Marvin,

Using the tools you mentioned, I was able to see there is load on the 2 'unused' cores. However, the load is low (<1%) and therefore, not visible on the graphs in FMC.

Thanks!
