[root@node1 bin]# pwd
/usr/local/zabbixagent/bin
[root@node1 bin]# ls
disk_discovery.sh  disk_status.sh  zabbix_get  zabbix_sender
[root@node1 bin]# cat disk_discovery.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 'ntt{'
        printf ""{#DISK_NAME}":"${diskarray[$i]}"}"
        if [ $i -lt $[$length-1] ];then
                printf ','
        fi
done
printf  "nt]n"
printf "}n"
[root@node1 bin]# sh disk_discovery.sh 
{
        "data":[
                {"{#DISK_NAME}":"sda"},
                {"{#DISK_NAME}":"sdb"},
                {"{#DISK_NAME}":"sdc"},
                {"{#DISK_NAME}":"sdd"},
                {"{#DISK_NAME}":"sde"},
                {"{#DISK_NAME}":"sdf"},
                {"{#DISK_NAME}":"sdg"}
        ]
}

[root@node1 bin]# /usr/local/zabbixagent/bin/zabbix_get -s 127.0.0.1 -p 10050 -k "disk.discovery"


[root@node1 bin]# 

service zabbix_agentd restart也做过了
