Measures reported by UspChanProcTest

A channel processor (CHP) which is contained in a channel adapter (CHA), processes the host commands and controls data transfer between hosts and the cache. A channel adapter contains multiple channel processors that process host commands and control data transfer. If monitoring data shows high overall CHP usage, you should consider installing additional CHAs. If monitoring data shows the imbalance usage of the CHP, you should consider moving some devices that are defined on overloaded ports to ports with lower-usage CHPs to balance the front-end usage.

This test is used to identify the usage of the Channel Processor.
