页面定制：https://github.com/firehol/netdata/wiki/Custom-Dashboards
wiki中提到页面需要一个header：
<!DOCTYPE html> <html lang="en"> <head> <title>Your dashboard</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <meta charset="utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"> <meta name="viewport" content="width=device-width, initial-scale=1"> <meta name="apple-mobile-web-app-capable" content="yes"> <meta name="apple-mobile-web-app-status-bar-style" content="black-translucent"> <!-- here we will add dashboard.js --> </head> <body> <!-- here we will add charts --> </body> </html>
页面定制：
1、页面数据加载和样式的展示都是依赖netdata server服务dashboard.js实现的，如果自定义页面中有多台服务器数据，dashboard从一台中加载一遍即可
2、数据获取依赖两个元素属性，data-netdata=""和data-host="http://netdata:19999/"，data-netdata是监控项名例如“system.cpu”，data-host是数据源服务器
3、如果元素没有自定义样式，netdata会默认选择监控项的样式
4、数据样式data-chart-library默认是dygraph（区域图），还有表盘样式easypiechart和gauge等
5、自定义样式有data-after=""/data-before=""时间区域，长宽高、最大值等，参考wiki即可
下面是两台虚拟机的自定义页面代码

如果出现页面样式或js不兼容，可以调整dashboard.js中的引用。
