zabbix--監控MySQL性能

Zabbix 自帶模板監控 MySQL 性能

通過自帶的 Template DB MySQL 模板監控 MySQL 性能

具體步驟：

1）創建腳本存放目錄並編輯腳本

# mkdir /etc/zabbix/script

# vim /etc/zabbix/script/mysql_status.sh    //編輯腳本
#!/bin/bash

#用戶

#端口

#MySQL連接

if [ $# -ne "1" ];then
    echo "arg error!"
fi

case $1 in

        result=`${CONNECTION} status 2>/dev/null |awk '{print $2}'`
        echo $result
        ;;

        result=`${CONNECTION} status 2>/dev/null |awk '{print $6}'`
        echo $result
        ;;
    Com_update)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_update" |awk '{print $4}'`
        echo $result
        ;;
    Slow_queries)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Slow_queries" |awk '{print $4}'`
        echo $result
        ;;
    Com_select)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_select" |awk '{print $4}'`
        echo $result
        ;;
    Com_rollback)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_rollback" |awk '{print $4}'`
        echo $result
        ;;
    Com_insert)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_insert" |awk '{print $4}'`
        echo $result
        ;;
    Com_delete)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_delete" |awk '{print $4}'`
        echo $result
        ;;
    Com_commit)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_commit" |awk '{print $4}'`
        echo $result
        ;;
    Bytes_sent)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Bytes_sent" |awk '{print $4}'`
        echo $result
        ;;
    Bytes_received)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Bytes_received" |awk '{print $4}'`
        echo $result
        ;;
    Com_begin)
        result=`${CONNECTION} extended-status 2>/dev/null |grep -w "Com_begin" |awk '{print $4}'`
        echo $result
        ;;*)
        echo "Usage:$0(Uptime|Questions|Com_update|Slow_queries|Com_select|Com_rollback|Com_insert|Com_delete|Com_commit|Bytes_sent|Bytes_received|Com_begin)"
        ;;
esac

# chmod +x /etc/zabbix/script/mysql_status.sh    //給腳本賦予執行權限

2）修改zabbix-agent配置文件，默認有一個MySQL的子配置文件，直接編輯該文件即可

# vim /etc/zabbix/zabbix_agentd.d/userparameter_mysql.conf
#獲取MySQL性能指標，這個是上一步編輯好的腳本
UserParameter=mysql.status[*],/etc/zabbix/script/mysql_status.sh $1
#獲取MySQL運行狀態
UserParameter=mysql.ping,mysqladmin -u root -h localhost -pIjRMv3l6TQIEjvb9nIX5 ping 2>/dev/null | grep -c alive
#獲取MySQL版本
UserParameter=mysql.version,mysql -V

3）重啟 zabbix-agent 

# service zabbix-agent restart

4）Web界面配置、點擊需要配置的主機，進去添加鏈接模板，自帶的Template DB MySQL

5）配置完成后等一會兒就可以查看到監控主機的MySQL監控信息

 查看監控主機的 MySQL bandwidth 圖形

查看監控主機的 MySQL operations 圖形

說明：如果發現監控沒有數據，請排查如下問題

1. zabbix客戶端是否重啟
2. 腳本是否有執行權限
3. 數據庫是否有權限
4. 環境變量是否有問題
