Name | Collection location | Scope of coverage | Unit(s) of measure | Definition | Method of Measurement | Sources of Error | Comments |
|---|---|---|---|---|---|---|---|
| cpu_idle | Host | The host CPUs, individually or total usage summed across all CPUs | nanoseconds or percentage | Time the host CPU spends idle. | |||
| cpu_nice | Host | The host CPUs, individually or total usage summed across all CPUs | nanoseconds or percentage | Time the host CPU spent running user space processes that have been niced. The priority level a user space process can be tweaked by adjusting its niceness. | |||

| cpu_softirq | Host | The host CPUs, individually or total usage summed across all CPUs | nanoseconds or percentage | ||||
| cpu_steal | Host | The host CPUs, individually or total usage summed across all CPUs | nanoseconds or percentage | ||||
| cpu_system | Host | The host CPUs, individually or total usage summed across all CPUs | nanoseconds or percentage | ||||
| cpu_user | Host | The host CPUs, individually or total usage summed across all CPUs | nanoseconds or percentage | ||||
| cpu_wait | Host | The host CPUs, individually or total usage summed across all CPUs | nanoseconds or percentage | ||||
| total_vcpu_utilization | Host | The host CPUs used by a guest, total usage summed across all CPUs | nanoseconds or percentage |
