linux - top %cpu 缩写是什么意思？

Question

有谁知道顶部进程表标题中的 %CPU 行中的两个字母缩写是什么意思？这是运行 top 的示例输出。

top - 15:10:34 up 8 days,  5:11,  1 user,  load average: 0.10, 3.80, 26.82
Tasks:   1 total,   0 running,   1 sleeping,   0 stopped,   0 zombie
%Cpu(s):  0.3 us,  0.7 sy,  0.0 ni, 98.0 id,  1.1 wa,  0.0 hi,  0.0 si,  0.0 st
KiB Mem:   2051456 total,   623544 used,  1427912 free,     1292 buffers
KiB Swap:  3203068 total,   147188 used,  3055880 free,    38352 cached

这是我的猜测和我不知道的。

us = user
sy = system
ni = ?
id = idle?
wa = ?
hi = ?
si = ?
st = ?

Answer 1

在“top”中，us、sy、ni、id、wa、hi、si 和 st 是什么(用于 CPU 使用率)？

• us - user cpu time (or) % CPU time spent in user space
• sy - system cpu time (or) % CPU time spent in kernel space
• ni - user nice cpu time (or) % CPU time spent on low priority processes
• id - idle cpu time (or) % CPU time spent idle
• wa - io wait cpu time (or) % CPU time spent in wait (on disk)
• hi - hardware irq (or) % CPU time spent servicing/handling hardware interrupts
• si - software irq (or) % CPU time spent servicing/handling software interrupts
• st - steal time % CPU time in involuntary wait by virtual cpu while hypervisor is servicing another processor (or) % CPU time stolen from a virtual machine
