本文主要是介绍TOP命令 %Cpu(s)解读 CPU状态信息us,sy,ni,id,wa,hi,si,st含义，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
使用系统命令top即可看到如下类似信息：Cpu(s): 0.0%us, 0.5%sy, 0.0%ni, 99.5%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st
但不知什么含义？google之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（来源http://bbs.chinaunix.net/thread-1958596-1-1.html） 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)
