Overview
CPU Metrics
CpuUserTime
The percentage of total CPU time spent executing code in user mode.
Also see:
CpuNiceTime
- CpuNiceTime (GitHub)
- nice - time in USER_HZ units spent in user mode with low priority (nice).
CpuKernelTime
- CpuKernelTime (GitHub)
- system - time in USER_HZ units spent in system mode: kernel executing system calls on behalf of processes.
CpuIdleTime
- CpuIdleTime (GitHub)
- idle - time in USER_HZ units spent in idle mode. This value should be USER_HZ times the second entry in /proc/uptime.
CpuIoWaitTime
- CpuIoWaitTime (GitHub)
- iowait - time in USER_HZ units processes are waiting for I/O to complete. The CPU will not wait for IO, it will be schedule onto another task or will enter idle state. When a CPU goes into idle state for outstanding task I/O, another task will be scheduled on this CPU. On a multi-core CPU, the task waiting for I/O to complete is not running on any CPU, so the iowait of each CPU is difficult to calculate.
CpuHardwareInterruptTime
- CpuHardwareInterruptTime (GitHub)
- irq - time in USER_HZ units spent servicing hardware interrupts.
CpuSoftwareInterruptTime
- softirq - time in USER_HZ units spent servicing softirqs.
- CpuSoftwareInterruptTime (GitHub)
CpuStolenTime
- steal - time in USER_HZ units spent in other operating systems when running in a virtualized environment.
