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

The percentage of total CPU time spent executing code in user mode with low priority (nice).

Also see:

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

CpuKernelTime

The percentage of total CPU time spent executing system calls on behalf of processes.

Also see:

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

CpuIdleTime

The percentage of total CPU time spent in idle mode.

Also see:

• /proc/stat cpu idle time reading
• GitHub CpuIdleTime

CpuIoWaitTime

The percentage of total CPU time spent 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.

Also see:

• /proc/stat cpu iowait time reading
• GitHub CpuIoWaitTime

CpuHardwareInterruptTime

The percentage of total CPU time spent servicing hardware interrupts.

Also see:

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

CpuSoftwareInterruptTime

The percentage of total CPU time spent servicing software interrupts.

Also see:

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

CpuStolenTime

The percentage of total CPU time spent in other operating systems when running in a virtualized environment. More details:
