1.磁盘发现脚本
vim disk_io.sh
#!/bin/bash
diskarray=(`cat /proc/diskstats |grep -E "\bsd[a-z]\b|\bxvd[a-z]\b|\bvd[a-z]\b"|awk ‘{print $3}‘|sort|uniq 2>/dev/null`)
length=${#diskarray[@]}
printf "{\n"
printf ‘\t‘"\"data\":["
for ((i=0;i<$length;i++))
do
printf ‘\n\t\t{‘
printf "\"{#DISK_NAME}\":\"${diskarray[$i]}\"}"
if [ $i -lt $[$length-1] ];then
printf ‘,‘
fi
done
printf "\n\t]\n"
printf "}\n"
2.磁盘io状态脚本
vim disk_stats.sh
#/bin/sh
device=$1
item=$2
case $item in
rrqm)
/usr/bin/tail -n20 /tmp/iostat_output |grep "\b$device\b"|tail -1|awk ‘{print $2}‘

3.增加用户自定义的参数表
vim /usr/local/zabbix-agent/etc/zabbix_agentd.conf #add the two lines UserParameter=disk.discovery[*],/bin/bash /usr/local/zabbix-agent/scripts/disk_io.sh UserParameter=disk.status[*],/bin/bash /usr/local/zabbix-agent/scripts/disk_stats.sh $1 $2
4.重启进程
/etc/init.d/zabbix_agentd restart
3.创建模板
4.创建discover rule
5.创建item prototype
6.创建Graph prototype
7.查看监控
