楼主

提醒：本文只是一个提示，TOP参数组合起来非常强大，单纯看中断的话，可以用systat或vmstat查看。

mso-hansi-font-family:"Times New Roman"">
mso-hansi-font-family:"Times New Roman"">

mso-hansi-font-family:"Times New Roman"">使用命令为：

top –IPSH

mso-hansi-font-family:"Times New Roman"">解释：

-I

"Times New Roman""> 不显示idle
"Times New Roman"">状态的进程，这个选项在进程多的时候特别有用，特别是php-fpm
"Times New Roman"">等进程数量较多的场合。

-P

"Times New Roman""> 显示每个CPU
"Times New Roman"">的信息，像Linux
"Times New Roman"">中默认的一样。

-H

"Times New Roman"">显示线程信息，默认情况下，只显示进程信息，把所有线程统计都归属到相关的进程中去。

-S

"Times New Roman"">显示系统进程，默认情况下，像idle

"Times New Roman"">、swap

宋体;mso-ascii-font-family:"Times New Roman";mso-hansi-font-family:"Times New Roman"">、intr
mso-hansi-font-family:"Times New Roman"">（即中断）等系统进程并不显示，这个选项强制显示这些进程。

mso-hansi-font-family:"Times New Roman"">来个示例：
