shell 监控磁盘空间并自动报警实例
当Linux磁盘分区达到70%时，自动发送邮件报警，使用前提：在被监控服务器上开启sendmail即可。我用perl写的实现同样的功能：http://salog.blog.51cto.com/318402/360256# cat diskme.sh
#!/bin/sh
admin_addr="taobao@ourgame.com"
ipaddr=`ifconfig eth0 | awk'/inet/{print $2}' | awk -F ":" '{print $2}'`
df -k | grep 'dev' > MESGF
while read LINE
do
dev=`echo $LINE | awk '{print $1}'`
use=`echo $LINE | awk '{print $5+0}'`
mnt=`echo $LINE | awk '{print $6}'`
if [ $use -ge 70 ];then
echo "Warning:$DEV Disk partition space usage over ($mnt used $use %)" > taobao
fi
done < MESGF
if [ -s taobao ];then
mail -s"${ipaddr} The Disk is full" $admin_addr < taobao
fi
rm -rf taobao
rm -rf MESGF
