How the Property Values are Derived
The min, max, average, min time, and max time values are calculated over a 30 second moving window. In this 30 second window, CPU utilization is calculated every 5 seconds and the min, max, and average values are calculated over these 6 samples.
The time instant at which the minimum and maximum values occur within the last 30 second window are displayed in epoch time format.
Operationsal State Data for the System CPU(s)
- hardware-interrupt - Percentage of CPU time spent servicing hardware interrupts
- software-interrupt - Percentage of CPU time spent servicing software interrupts
- kernel - Percentage of CPU time spent running in kernel space
- user - Percentage of CPU time spent running in user space
- idle - Percentage of CPU time spent idle
- total - Total CPU utilization
- nice - Percentage of CPU time spent running low-priority (niced) user processes
- wait - Percentage of CPU time spent waiting for I/O
