Ganglia页自定义视图

官网自带的页面指标太拥挤，同一个组各指标的顺序不能指定(默认好像是按名称排序的)不便于观察。通过页面的Views页签可以查看自定的图标。

在conf文件夹(由conf_default.php中views_dir指定)下面建立文件名以 view 开头的json文件。通过Views还可以聚合多个指标，在一个图中查看整体的变化趋势。配置聚合视图前可以先在 Aggregate Graphs 弄出来先瞧一瞧。

[root@cu2 ~]# cd /var/www/html/ganglia/
# 查看view放置的位置
[root@cu2 ganglia]# grep views_dir conf_default.php 
$conf['views_dir'] = $conf['gweb_confdir'] . '/conf';

# view配置目录
[root@cu2 conf]$ ll
