What does RMF report on CHIN hardware resource utilization, like wait on processor?

I don't have a pass to enter the hallowed portal of z/os systems programming.
Before I risk disturbing the demi-Gods, what sort of issue are you suggesting here?

Number of Adapters and dispatchers seems well provisioned, but does the LPAR have sufficient CPU horsepower to keep up with the adapter and dispatcher workload? MVS sees processors in whole numbers, but it’s possible that the LPAR has 0.25 CPU allocated to it.

These CHINs are on production Z14s - not hitting 100% CPU overall.

SMF reporting this? Or, RMF?
