Zabbix 监控 NySQL
Zabbix监控MySQL首先，大家如果看到有什么不懂的地方，欢迎吐槽！！！
我会在当天或者第二天及时回复，并且改进~~
Zabbix 3.0中已经有Mysql监控模板了，所以我们只要引用ZabbixServer自带的模版即可。
一、在Zabbix_Agentd中添加Include目录，这里面存放Zabbix的Item监控项-Key.
vim /usr/local/zabbix/etc/zabbix_agentd.conf
Include=/usr/local/zabbix/etc/zabbix_agentd.conf.d/
二、创建监控Mysql的Key
该Key的目录为上面Include指定的路径
[*]check_mysql_performance_key
监控Mysql性能
vim /usr/local/zabbix/etc/zabbix_agentd.conf.d/check_mysql_performance_key
UserParameter=mysql.version,/usr/local/mysql/bin/mysql -V
UserParameter=mysql.ping,/usr/local/mysql/bin/mysqladmin -uzabbix -pzabbix -S /usr/local/mysql/data/mysql.sock ping 2> /dev/null | grep -c alive
UserParameter=mysql.status
[*],/usr/local/zabbix/shell/check_mysql_performance.sh $1 $2
[*]check_mysql_slave_key
监控Mysql主从是否同步
vim /usr/local/zabbix/etc/zabbix_agentd.conf.d/check_mysql_slave_key
UserParameter=mysql.slave
[*],/usr/local/zabbix/shell/check_mysql_slave.sh $1 $2
三、创建监控Mysql的脚本
其实在上面Key步骤中已经知名了Mysql监控脚本名称及路径，脚本记得加权限哦~~
脚本内容贴在文章尾部，这里内容繁多，所以不再赘述，下面是脚本路径
/usr/local/zabbix/shell/check_mysql_performance.sh
/usr/local/zabbix/shell/check_mysql_slave.sh
四、启动Zabbix_Agentd
/usr/local/zabbix/sbin/zabbix_agentd
五、Zabbix_Agentd脚本及监控item已经设置好，下面我们在Zabbix_Web界面为需要监控的主机设置模板
点击-Configuration-Hosts
选择需要监控的主机，我们来链接Mysql的监控模板
在Templates页面中选择Select，然后添加Templates App MySQL模板
接着点击主页中的Screen，创建一个Mysql的Screen
创建一个Mysql_Monitoring的screen，然后添加两个图像
Mysql_bandwidth
Mysql_operations
看到这个图片，OK，你的Mysql监控就此完成啦~~
下面是Mysql性能监控脚本
