BIG IP Analysis Plane

Hello,

I did not find yet the article which processes utilize the "analysis plane". But you can find out by yourself because the Processes for this plane are always on the last uneven CPU Core

Analysis plane-related processes are generally pinned to the highest odd-numbered core and no control or analysis process have access to the even cores. The processes pinned to the analysis plane typically consume all available CPU cycles when running, which is why they are assigned to a single, specific core

Maybe someone else will find some reference article but maybe this will already help you out.

Also if you are looking because the usage on this core / plane is high, this is normal and expected behavior
