zabbix监控mysql_MySQL

1、zabbix添加mysql的监控模板（temple-app-mysql）之后，还需要在客户端添加key去取值。

2、编写脚本，获取mysql的各种状态值。可以固定一个目录，专门存放监控脚本。比如/usr/local/zabbix/scripts/chk_mysql.sh

#!/bin/bash

        result=`${MYSQL_CONN} status|cut -f2 -d":"|cut -f1 -d"T"` 
        echo $result 
        ;; 
    Com_update) 
        result=`${MYSQL_CONN} extended-status |grep -w "Com_update"|cut -d"|" -f3` 
        echo $result 
        ;; 
    Slow_queries) 
        result=`${MYSQL_CONN} status |cut -f5 -d":"|cut -f1 -d"O"` 
        echo $result

        result=`${MYSQL_CONN} extended-status |grep -w "Com_select"|cut -d"|" -f3` 
        echo $result 
                ;;

        result=`${MYSQL_CONN} extended-status |grep -w "Com_rollback"|cut -d"|" -f3`

        result=`${MYSQL_CONN} status|cut -f4 -d":"|cut -f1 -d"S"` 
                echo $result 
                ;; 
    Com_insert) 
        result=`${MYSQL_CONN} extended-status |grep -w "Com_insert"|cut -d"|" -f3` 
                echo $result 
                ;; 
    Com_delete) 
        result=`${MYSQL_CONN} extended-status |grep -w "Com_delete"|cut -d"|" -f3` 
                echo $result 
                ;; 
    Com_commit) 
        result=`${MYSQL_CONN} extended-status |grep -w "Com_commit"|cut -d"|" -f3`

        result=`${MYSQL_CONN} extended-status |grep -w "Bytes_sent" |cut -d"|" -f3` 
                echo $result

    Bytes_received) 
        result=`${MYSQL_CONN} extended-status |grep -w "Bytes_received" |cut -d"|" -f3` 
                echo $result

                echo $result

        ;;

3、修改zabbix的配置文件/usr/local/zabbix-agentd/etc/zabbix_agentd.conf，添加

#获取mysql版本
UserParameter=mysql.version,mysql -V
##获取mysql性能指标,这个是上面定义好的脚本
UserParameter=mysql.status[*],bash /alidata/zabbix-agentd/scripts/chk_mysql.sh $1
##获取mysql运行状态
UserParameter=mysql.ping,/alidata/mysql/bin/mysqladmin -uroot -pliujinWANG1985 -P3306 -h127.0.0.1  ping | grep -c alive
UserParameter=mysql.process,/alidata/mysql/bin/mysql -uroot -pliujinWANG1985 -P3306 -h127.0.0.1  -e "show processlist" 2>/dev/null|wc -l

4、重启zabbix的客户端
