Difference between sh processes platform and sh processes cpu

[kubn2]

Hi,

So recently I'm having fun with Cisco CSR 1000V which is virtual router and I noticed one thing. Under heavy load show process platform showing high usage around 70-90% meanwhile process CPU sits at 0-2%. Can you tell me what is the difference between it? Is platform showing like general usage of everything? Or this is usage of some data plane?

Hi

To understand these commands and outputs, you need to understand how ios-xe works (new ios generation).

The show process cpu is to show usage within iosd daemon whereas show process platform is to see usage within the Linux kernel.

Here a link explaining it:
