linux中top指令：CPU状态信息us,sy,ni,id,wa,hi,si,st含义

• 更多分享：www.catbro.cn

  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
