硬盘使用率定额监控

一个用来监控硬盘使用率的小脚本，用来监控当硬盘使用率超过一定限额就发邮件报警。

#!/bin/bash

ADMIN='localhost@localhost'

# set alert level 90% is default

ALERT=90

output=`df -H | grep -vE '^Filesystem|tmpfs|cdrom|已用' | awk '{ print $5 " " $1 }'`

while :

do

#echo $output

usep=`echo $output | awk '{ print $1}' | cut -d'%' -f1`

partition=`echo $output | awk '{ print $2 }'`

if [ $usep -ge $ALERT ]; then

mail -s "Alert: Almost out of disk space "$partition $usep" on $(hostname) as on $(date)" $ADMIN

fi
