Linux Top Process

When you used Linux top process to monitor your server/PC, you might want to know what meant by the Cpu(s) variable used in percentage.

Eg.

top – 16:24:04 up 80 days, 18:23,  1 user,  load average: 0.48, 0.46, 0.44
Tasks: 226 total,   2 running, 222 sleeping,   0 stopped,   2 zombie
Cpu(s):  2.2%us,  2.5%sy,  0.4%ni, 92.0%id,  3.0%wa,  0.0%hi,  0.0%si,  0.0%st

1. us -> User CPU time: The time the CPU has spent running users’ processes that are not niced.
2. sy -> System CPU time: The time the CPU has spent running the kernel and its processes.
3. ni -> Nice CPU time: The time the CPU has spent running users’ proccess that have been niced.
4. wa -> iowait: Amount of time the CPU has been waiting for I/O to complete.
5. hi -> Hardware IRQ: The amount of time the CPU has been servicing hardware interrupts.
6. si -> Software Interrupts.: The amount of time the CPU has been servicing software interrupts.
