CPU Metrics

CpuUserTime

The percentage of total CPU time spent executing code in user mode.

Also see:

• /proc/stat cpu user time reading
• GitHub CpuUserTime

CpuNiceTime

Also see:

• /proc/stat cpu nice time reading
• GitHub CpuNiceTime

• CpuNiceTime (GitHub)

• nice - time in USER_HZ units spent in user mode with low priority (nice).

CpuKernelTime

Also see:

• /proc/stat cpu system time reading
• GitHub CpuKernelTime

• CpuKernelTime (GitHub)

• system - time in USER_HZ units spent in system mode: kernel executing system calls on behalf of processes.

CpuIdleTime

Also see:

• /proc/stat cpu idle time reading
• GitHub 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

Also see:

• /proc/stat cpu iowait time reading
• GitHub 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

Also see:

• /proc/stat cpu irq time reading
• GitHub CpuHardwareInterruptTime

• CpuHardwareInterruptTime (GitHub)

• irq - time in USER_HZ units spent servicing hardware interrupts.

CpuSoftwareInterruptTime

Also see:

• /proc/stat cpu softirq time reading
• GitHub CpuSoftwareInterruptTime

• softirq - time in USER_HZ units spent servicing softirqs.

• CpuSoftwareInterruptTime (GitHub)

CpuStolenTime

Also see:

• /proc/stat cpu steal time reading
• GitHub CpuStolenTime

• steal - time in USER_HZ units spent in other operating systems when running in a virtualized environment.

• CpuStolenTime (GitHub)
