zabbix监控mysql

zabbix自带MySQL的监控模板(Template App MySQL)，但不能直接使用，需要在客户端上进行一些设置。

1、在客户端编写mysql监控脚本

#!/bin/bash 

MYSQL_SOCK="/var/lib/mysql/mysql.sock"  
ARGS=1 
if [ $# -ne "$ARGS" ];then 
    echo "Please input one arguement:" 
fi 
case $1 in 
    Uptime) 
        result=`/usr/bin/mysqladmin -uzabbix -ppassword -S $MYSQL_SOCK status 2>/dev/null|awk -F'[: ]+' '{print $2}'` 
        echo $result 
        ;; 
    Com_update) 
        result=`/usr/bin/mysqladmin -uzabbix -ppassword -S $MYSQL_SOCK extended-status 2>/dev/null|awk -F'[ |]+' '/Com_update>/{print $3}'` 
        echo $result 
        ;; 
    Slow_queries) 
        result=`/usr/bin/mysqladmin -uzabbix -ppassword -S $MYSQL_SOCK status 2>/dev/null|awk -F'[: ]+' '{print $9}'` 
        echo $result 
        ;; 
    Com_select) 
        result=`/usr/bin/mysqladmin -uzabbix -ppassword -S $MYSQL_SOCK extended-status 2>/dev/null|awk -F'[ |]+' '/Com_select>/{print $3}'` 
        echo $result 
        ;; 
    Com_rollback) 
        result=`/usr/bin/mysqladmin -uzabbix -ppassword -S $MYSQL_SOCK extended-status 2>/dev/null|awk -F'[ |]+' '/Com_rollback>/{print $3}'` 
        echo $result 
        ;; 
    Questions) 
        result=`/usr/bin/mysqladmin -uzabbix -ppassword -S $MYSQL_SOCK status 2>/dev/null|awk -F'[: ]+' '{print $6}'` 
        echo $result 
        ;; 
    Com_insert) 
        result=`/usr/bin/mysqladmin -uzabbix -ppassword -S $MYSQL_SOCK extended-status 2>/dev/null|awk -F'[ |]+' '/Com_insert>/{print $3}'` 
        echo $result 
        ;; 
    Com_delete) 
        result=`/usr/bin/mysqladmin -uzabbix -ppassword -S $MYSQL_SOCK extended-status 2>/dev/null|awk -F'[ |]+' '/Com_delete>/{print $3}'` 
        echo $result 
        ;; 
    Com_commit) 
        result=`/usr/bin/mysqladmin -uzabbix -ppassword -S $MYSQL_SOCK extended-status 2>/dev/null|awk -F'[ |]+' '/Com_commit>/{print $3}'` 
        echo $result 
        ;; 
    Bytes_sent) 
        result=`/usr/bin/mysqladmin -uzabbix -ppassword -S $MYSQL_SOCK extended-status 2>/dev/null|awk -F'[ |]+' '/Bytes_sent>/{print $3}'` 
        echo $result 
        ;; 
    Bytes_received) 
        result=`/usr/bin/mysqladmin -uzabbix -ppassword -S $MYSQL_SOCK extended-status 2>/dev/null|awk -F'[ |]+' '/Bytes_received>/{print $3}'` 
        echo $result 
        ;; 
    Com_begin) 
        result=`/usr/bin/mysqladmin -uzabbix -ppassword -S $MYSQL_SOCK extended-status 2>/dev/null|awk -F'[ |]+' '/Com_begin>/{print $3}'` 
        echo $result 
        ;; 
    *) 
        echo "Usage:$0(Uptime|Com_update|Slow_queries|Com_select|Com_rollback|Questions)" 
        ;; 
esac

2、在mysql服务器上面创建一个用于zabbix监控的用户（无权限）

GRANT USAGE ON *.* TO 'zabbix'@'localhost' IDENTIFIED BY 'password';

3、修改客户端zabbix设置

编辑zabbix_agentd.conf配置文件，添加如下内容：

UserParameter=mysql.version,mysql -V
UserParameter=mysql.ping,mysqladmin -uzabbix -plkpower -S /var/lib/mysql/mysql.sock ping 2>/dev/null| grep -c alive
UserParameter=mysql.status[*],/data/zabbix/externalscripts/zabbix_mysql_status.sh $1

然后重启zabbix_agentd服务。

4、服务端测试是否可以正常取值

5、在zabbix的监控上添加MySQL的模板（Template App MySQL）

监控效果图如下：
