cpus (host statistics)
The cpus resource allows an administrator to view information about the CPUs reported by the host. Selection of the cpus link in the host resource generates a list of all CPUs available on the host: you can produce data for each individual CPU, or use the aggregate all option to produce information for all CPUs.
AMPS calculates these percentages from changes in CPU time counters between statistics samples. Values are reported as whole-number percentages. The all entry represents aggregate CPU time across the host.
Notice that AMPS also records CPU statistics for the AMPS process itself.
| Element | Description | Type |
|---|---|---|
idle_percent | Percent of CPU time that the system was waiting for an operation other than an I/O request to complete. | interval average |
iowait_percent | Percent of CPU time spent waiting for I/O requests to complete. | interval average |
system_percent | Percent of CPU utilization time which occurred while executing kernel processes. | interval average |
user_percent | Percent of CPU utilization time which occurred while running at the application level. | interval average |
