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.
