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。
