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 |
