原文地址:Netdata Mysql运行情况监控插件 作者:百联达

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


点击(此处)折叠或打开

  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


点击(此处)折叠或打开

  1. #!/bin/bash

  2. # http://dev.mysql.com/doc/refman/5.0/en/server-status-variables.html
  3. #
  4. # https://dev.mysql.com/doc/refman/5.1/en/show-status.html
  5. # SHOW STATUS provides server status information (see Section 5.1.6, “Server Status Variables”).
  6. # This statement does not require any privilege.
  7. # It requires only the ability to connect to the server.
