CPU状态信息us,sy,ni,id,wa,hi,si,st含义

2022-08-09 16:47:00 【编程工人】

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

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
