一：mysql文件配置
/usr/local/netdata/etc/netdata  增加配置文件mysql.conf

1. mysql_cmds[MY_A]="/usr/local/mysql/bin/mysql"

2. mysql_opts[MY_A]="-h localhost -uroot"

二：mysql.chart.sh 插件脚本

1. #!/bin/bash

3. # http://dev.mysql.com/doc/refman/5.0/en/server-status-variables.html

4. #

5. # https://dev.mysql.com/doc/refman/5.1/en/show-status.html

6. # SHOW STATUS provides server status information (see Section 5.1.6, “Server Status Variables”).

7. # This statement does not require any privilege.

8. # It requires only the ability to connect to the server.
