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。
