CPU狀態信息us,sy,ni,id,wa,hi,si,st含義

在使用linux系統命令top便可看到以下相似信息：

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

百度知

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"

中文翻譯爲：

us 用戶空間佔用CPU百分比
sy 內核空間佔用CPU百分比
ni 用戶進程空間內改變過優先級的進程佔用CPU百分比
id 空閒CPU百分比
wa 等待輸入輸出的CPU時間百分比
hi 硬件中斷
si 軟件中斷
st: 實時（來源http://bbs.chinaunix.net/thread-1958596-1-1.html）
