for interpreting the top command's %CPU usage stats.
- us: Amount of time the CPU spends executing processes for people in “user space.”
- sy: Amount of time spent running system “kernel space” processes.
- ni: Amount of time spent executing processes with a manually set nice value.
- id: Amount of CPU idle time.
- wa: Amount of time the CPU spends waiting for I/O to complete.
- hi: Amount of time spent servicing hardware interrupts.
- si: Amount of time spent servicing software interrupts.
- st: Amount of time lost due to running virtual machines (“steal time”).
Interestingly,
has a mistake about idle time - it says, "id is the percent of time idle (if high, CPU may be overworked)." It should be, if low, CPU may be overworked, right?
