CPU Metrics
| Metric Name | Description | Basic or Server Visibility | Windows | Linux | Solaris | AIX | Default Monitoring Mode |
|---|---|---|---|---|---|---|---|
| %Idle | Percentage of time the CPU was idle; the CPU had completed its tasks and has nothing to do. | Basic | Diagnostic | ||||
| %Busy | Percentage of time the CPU was busy processing system or user requests; this metric includes CPU Stolen time. | Basic | KPI | ||||
| %Stolen4 | Usually, stolen time is the percentage of time a virtual CPU waits for a real CPU while the hypervisor is servicing another virtual processor. | Basic | KPI | ||||
| %Nice | Percentage of CPU time spent on low priority processes. | Server Visibility | Advanced | ||||
| System | Percentage of time the CPU was busy processing kernel code. | Server Visibility | KPI | ||||
| User | Percentage of time the CPU was busy processing non-kernel code. | Server Visibility | KPI | ||||
| IOWait | Percentage of CPU time spent waiting for an I/O request. | Server Visibility | KPI | ||||
| %Irq | Percentage of CPU time spent servicing hardware interrupts. | Server Visibility | Diagnostic | ||||
| %SoftIrq | Percentage of CPU time spent servicing software interrupts. | Server Visibility | Advanced | ||||
| %Busy 95th Percentile2 | The CPU %Busy percentage was at this level or lower 95% of the time. | Server Visibility | KPI | ||||
| IOWait 95th Percentile2 | The CPU time spent waiting on disk I/O that was not exceeded during 95% of the observed period, highlighting near-worst-case storage latency. | Server Visibility | KPI |
