Virtual-processor metrics

The onperf utility can display metrics for a virtual-processor class.

These metrics take a virtual-processor class as a metric scope (cpu, aio, kaio, and so on). Each metric value represents a sum across all instances of this virtual-processor class.
Metric Name Description
User Time Accumulated user time for a class
System Time Accumulated system time for a class
Semaphore Operations Total count of semaphore operations
Busy Waits Number of times that virtual processors in class avoided a context switch by spinning in a loop before going to sleep
Spins Number of times through the loop
I/O Operations Number of I/O operations per second
I/O Reads Number of read operations per second
I/O Writes Number of write operations per second
