传统的mysql 服务器 用zabbix很容易实现，单对于云端的mysql 实例 我想大家都是用的云自带的监控。我们前端时间aws 云端mysql 实现主从 进程的出现问题，然而aws 自带的监控没有。
我们就想到 zabbix 实现对aws mysql 实例的监控。
1监控的服务远程去连接 awsmysql 取监控的数值就很容易实现了。
创建用户
GRANT USAGE,PROCESS,REPLICATION SLAVE,REPLICATION CLIENT ON *.* TO [email protected]‘10.%‘ IDENTIFIED BY ‘zabbixtest‘;
2.监控客户端 zabbix配置文件的
serParameter=mysqlstatustest[*],/data/scripts/zabbix/mysql_check.sh "$1 $2 $3 $4"
3监控脚本重写。这个就是比较麻烦的事情 在这里我贡献给大家，我用的是zabbix3.2 版本实现的。

mysql $1 $2 $3 $4
mysql 需要连接的数据的 用户 和密码还有 ip 就需要在模版里面写宏变量实现。
4模版的添加 rate 有几个key 我没写。
模版在附件 zabbix 3.0才能使用此模版
如果需要redis和memcache 模版 和远程监控实现方法 请联系我。
5注意事项
由于 所以的 mysql 实例的监控都是从这一台zabbix－agentd 取的数值
所以这台监控的机器 的压力很大
StartPollersUnreachable=10 server 需要优化这个参数
客户端的配置文件 需要优化超时时间和buffer 大小
6tip
脚本优化方向，可以写个crontab 把状态数据 存到临时文件里面 ，然后脚本 取这个文件里面的数值，这样连接数能降低很多，因为时间仓促 所以脚本没优化。
我们的 这一台监控 mysql redis memcached 实例 都是用的这个方式，而且都是这个机器取的 50个实例的数值 （1核2gb的监控 客户端）同时还是一个zabbix－proxy。
