远程硬盘资源监控通用脚本

一、建立一个通用shell脚本，通过ssh执行df命名获取对端硬盘信息。注意增加执行权限。

[iptv@ting-wo disk]$ more diskmonitor.sh 

#!/bin/bash

mailflag="true"

#check parameters count

if [ $# -ne 6 ];then

  echo 6 parameters needed:taskname client_ip_list port account maillist alertlimit

  echo example:diskmonitor.sh iptvservers 10.17.44.122 22 iptv abc@aaa.com 3

  echo \"3\" at the ednd means it will send alert mail if disk usage > 30%. 3表示超过30%就告警。

  return 1;

fi;

if [[ ! $6 =~ ^[0-9]$ ]];then

  echo "\$6 is the lowest limit of triger alert,must be a number and between 1-9."

  return 1;

fi;

echo "**********start**********"

taskname=$1

client_ip_list=$2

dir="/home/iptv/monitor/disk"

logfile=${dir}/disk${taskname}.log

mailfile=${dir}/mail${taskname}.txt

port=$3

account=$4

maillist=$5

limit=$6

date

echo taskname=$taskname,client_ip_list=$client_ip_list,port=$port,account=$account,maillist=$maillist

#echo "clean tmp file"

#cat /dev/null > $mailfile;

#cat /dev/null > $logfile;

#count ,how many disks > 30%;

for ip in ${client_ip_list};do

  echo "#####start looking ${ip}\'s disk info.#####"

  cat /dev/null > $mailfile;

  cat /dev/null > $logfile;

  echo ssh get disks info to $logfile

  ssh -p${port} ${account}@${ip} df -h > $logfile;

  if [ $? -ne 0 ];then 

    echo ssh error.exit loop.;

    break;

  fi;

  count=`cat $logfile| grep -v mnt|grep -c -E [${limit}-9][0-9]%\|100%`;

  echo disk alert count=$count

  if [ $count -gt 0 ];

  then 

    echo "start alerting by mail......"

    echo "This is a alert for ${ip}\'s disk usage." >> $mailfile

    echo "host address:${ip}" >> $mailfile

    echo "disk info:" >> $mailfile

    cat $logfile >> $mailfile

    if [ "$mailflag" == "true" ]; then 

      for mail in $maillist;do

        mail -s "disk alert for ${ip}" $mail < $mailfile;

      done;

    fi;

  fi;

  echo "#####end ${ip}#####"

done;

echo "*********end*********"

二、建立一个专用shell脚本，调用通用脚本。注意增加执行权限。

[iptv@ting-wo disk]$ more disk158.sh

#!/bin/bash

maillist="aaa@1234.com bbb@1234.com"

taskname=158

client_ip_list="11.22.33.158"

account=nginx

port=22

limit=3

#password=nginxUser*1

/home/iptv/monitor/disk/diskmonitor.sh "$taskname" "$client_ip_list" "$port" "$account" "$maillist" "$limit"

三、在cron中加入定期任务

0 6 * * * /home/iptv/monitor/disk/disk158.sh > /home/iptv/monitor/disk/crondisk158.log 2>&1

四、设置ssh对端免密码登录，略。
