4.服务器添加脚本和配置文件

客户端添加脚本

[root@zabbix /opt/zabbixsh 16:28:31&&123]#pwd
/opt/zabbixsh
[root@zabbix /opt/zabbixsh 16:28:39&&124]#ls
chk_disk.sh

脚本内容:
#!/bin/bash

#使用UserParameter=disk.all,/usr/local/zabbix/scripts/chk_disk.sh check_disk  #返回0严重 返回1警告 返回2 OK
##使用UserParameter=disk.all.inode,/usr/local/zabbix/scripts/chk_disk.sh  check_disk_inode #返回0严重 返回1警告 返回2 OK

DEBUG=0
function check_disk(){
    row=`df -Ph |wc -l`
    (( DEBUG )) && echo $row
    n=()
    for i in `seq 2 $row`
    do
        (( DEBUG )) && echo $i
        ava=`df -Ph |sed -n "$i"p|awk '{print $4}'`
        u_per=`df -Ph |sed -n "$i"p|sed -n "s/\%//"p|awk '{print $5}'`
        p_p=`df -h -P|sed -n "$i"p|awk '{print $6}'`
        ((DEBUG)) && echo "ava ${ava} , u_per ${u_per} , p_p ${p_p}"
        if [ ! -n "$(echo $u_per| sed -n "/^[0-9]+$/p")" ]
            then
                continue
        fi
        if [ "$u_per" -gt "94"  ];then
            n[$i]=0
        elif [ "$u_per" -gt "89" ];then
            n[$i]=1
        else
            n[$i]=2
        fi
    done
    echo ${n[*]} | sed "s/ /
/g" | sort -n | head -n1 
}

function check_disk_inode(){
    row=`df -iPh |wc -l`
    n=()
    for i in `seq 2 $row`
    do
        ava=`df -iPh |sed -n "$i"p|awk '{print $4}'`
        u_per=`df -iPh |sed -n "$i"p|sed -n "s/\%//"p|awk '{print $5}'`
        p_p=`df -ih -P|sed -n "$i"p|awk '{print $6}'`
        ((DEBUG)) && echo "ava ${ava} , u_per ${u_per} , p_p ${p_p}"
        if [ ! -n "$(echo $u_per| sed -n "/^[0-9]+$/p")" ]
            then
                continue
        fi
        if [ "$u_per" -gt "94"  ];then
            n[$i]=0
        elif [ "$u_per" -gt "89" ];then
            n[$i]=1
        else
            n[$i]=2
        fi
    done
    echo ${n[*]} | sed "s/ /
/g" | sort -n | head -n1
}

if [ "$1" == "check_disk" ]
    then
        check_disk
fi
if [ "$1" == "check_disk_inode" ]
    then
        check_disk_inode
fi  

if [ "$1" == "" ]
    then
        echo "usage:{check_disk|check_disk_inode}"
fi

 客户端添加zabbix_agentd配置文件

[root@zabbix /opt/zabbix/etc/zabbix_agentd.conf.d 16:33:10&&139]#pwd
/opt/zabbix/etc/zabbix_agentd.conf.d
[root@zabbix /opt/zabbix/etc/zabbix_agentd.conf.d 16:33:11&&140]#ls
crond.conf  disk.conf

crond.conf内容:
UserParameter=crond.ping,/sbin/pidof crond | wc -l

disk.conf内容:
UserParameter=disk.all,/opt/zabbixsh/chk_disk.sh check_disk
UserParameter=disk.all.inode,/opt/zabbixsh/chk_disk.sh check_disk_inode

 重启zabbix客户端
