  cme.sh网络流量监控使用

  [root@china213 ~]# cd /bin

  [root@china213 bin]# ./cme.sh

  cpu 99

  disk 39

  mem 38

  nic 19855 33 0

  [root@china213 bin]#

  CPU剩余率,磁盘剩余率,内存剩余率,以及网卡接收的bps,pps和dps(丢包)

  把下面内容用vi命令写入到cme.sh中[root@china213 bin]# vi cme.sh,同时用[root@china213 bin]# chmod x cme.sh增加可执行权限

  注意:shell文件开头必须以#!/bin/sh开始,在window中保存成cme.sh上传的时候会执行不了,可能是文件头的问题。

  ==============================不要把这行分各符放到cme.sh文件中=========================================
