[ACI Fabric Switch] Kernel CPU + User CPU = Total CPU Usage?

[Danial Haziq]

Above is the image of one of fabric switch in ACI. Is the Kernel CPU usage + User CPU usage will be the total of CPU usage of the fabric switch?

@Danial Haziq No the total CPU usage of a fabric switch in ACI isn’t just the sum of Kernel CPU and User CPU. Those two are part of the overall system CPU utilization, but there are also other processes, like management, platform, and system tasks, that contribute to total CPU usage. So, the overall CPU usage u see is usually higher than just Kernel + User.

hope it helps!

Hi @Enes Simnica ,

Thank you for your reply. So how to check and know the exact CPU usage of the fabric switch?

Thank you.

@Danial Haziq As far as I can remember from my last issue that i had similar to urs, u can check the exact CPU usage per process on an Aci fabric switch (N9000 in ACI mode) with:: show system internal sysmgr service summary.

or if u were on a standalone nx-os sw instead of Aci u'd use: show system internal processes cpu

hope it helps G, and PEACE!
