zhou2324

Cpu(s):  1.4%us,  1.4%sy,  0.0%ni, 48.6%id, 45.8%wa,  1.4%hi,  1.4%si,  0.0%st

sorry for i can't type chinese,the above is part of the result by running top command in terminal,
i don't know what's the meaning of 'us,sy,ni,id,wa,hi,si,st',so what's this abbreviations stand for?
is 'us' stands for 'the count of cpu used by user' and 'sy' means 'the count of cpu used by system',is that right?


pls help me ?
thanks!

i don't know  ...

I try to explain  these:
us: is meaning of "user CPU time"
sy: is meaning of "system CPU time"
ni: is meaning of" nice CPU time"
id: is meaning of "idle"
wa: is meaning of "iowait"
hi：is meaning of "hardware irq"
si : is meaning of "software irq"
st : is meaning of "steal time"

中文翻译为：

us 用户空间占用CPU百分比
sy 内核空间占用CPU百分比
ni 用户进程空间内改变过优先级的进程占用CPU百分比
id 空闲CPU百分比
wa 等待输入输出的CPU时间百分比
hi 硬件中断
si 软件中断
st: 实时

  2c. SUMMARY Area Fields
       The summary area fields  describing  CPU  statistics  are  abbreviated.
       They provide information about times spent in:
           us = user mode
           sy = system mode
           ni = low priority user mode (nice)
           id = idle task
           wa = I/O waiting
           hi = servicing IRQs
           si = servicing soft IRQs
           st = steal (time given to other DomU instances)
