Using Measure
CPU Entity
The CPU entity should be measured with the PROCESS entity to allow a more
accurate estimate of processor use to be derived and to give guidance for load
balancing. Example 20-5 is an example of a CPU entity display.
Determining Processor Use
To determine the processor use of an Expand line-handler process, you must add a
fraction of the Intr-Busy-Time count from the processor where the Expand line-handler
process is running to the Cpu-Busy-Time value for the Expand line-handler process.
This fraction can be estimated using the following formula:
PROCESS-Dispatches
is the value shown in the Dispatches counter of the PROCESS entity display.
CPU-Dispatches
is the value shown in the Dispatches counter of the CPU entity display.
Intr-Busy-Time
is a counter shown in the CPU entity display.
Send-Busy-Time
is a counter shown in the CPU entity display.
For example, you can use the following values from the PROCESS entity and CPU
entity displays shown above to determine the processor use of process $PATHF
running in processor 2:
