开发cloudify配方文件- Web Management Console

配置Web Management Console

Cloudify web management console提供一个基于web的图形用户界面来监控你的应用和其对应的服务。特别在Applications视图下，通过线性图和仪表盘小部件来展示被选中的服务监控指标，每个小部件展示默认的度量，但也可以通过下来菜单来选择其他度量值。度量面板的布局和下拉菜单都要在各自的服务描述文件中配置。

内置和自定义指标

默认情况下， Cloudify监控CPU和内存的使用率这些通用指标，但是它还可以使用下面的自定义机制监控其他更具体的指标

• Monitoring Probes closures that emit metrics and their current value.
• Monitoring Plugins  classes that emit metrics and their current value.

  Cloudify每5秒调用probe或插件，并返回一个包含指标名与对应值的Map，内置和自定义指标都要在web management console中展示

  配置指标部件

  在 web management console中， Applications视图包含一个专有的窗格来展示监控指标，并允许你通过下拉菜单来选择度量值。默认下，度量指标描述在widgets块中，布局在thewidgetsGroup块描述

  下面是PetClinic 应用下的Mongo 数据库服务描述文件下的userInterface块， metricGroups 块描述MongoDB的6个指标的指标组。 widgetGroups块描述上面6个指标的展示图表和布局。

  userInterface {         metricGroups = ([             metricGroup {                 name "MongoDB"                 metrics([                     "Open Cursors",                     "Current Active Connections",                     "Active Read Clients",                     "Active Write Clients",                     "Read Clients Waiting",                     "Write Clients Waiting"                                     ])             }         ])         widgetGroups = ([             widgetGroup {                 name "Open Cursors"                 widgets ([                     balanceGauge{metric = "Open Cursors"},                     barLineChart{                         metric "Open Cursors"                         axisYUnit Unit.REGULAR                     },                 ])             },             widgetGroup {                 name "Current Active Connections"                 widgets ([                     balanceGauge{metric = "Current Active Connections"},                     barLineChart{                         metric "Current Active Connections"                         axisYUnit Unit.REGULAR                     },                 ])             },                          widgetGroup {                 name "Active Read Clients"                 widgets ([                     balanceGauge{metric = "Active Read Clients"},                     barLineChart{                         metric "Active Read Clients"                         axisYUnit Unit.REGULAR                     },                 ])             },             widgetGroup {                 name "Active Write Clients"                 widgets ([                     balanceGauge{metric = "Active Write Clients"},                     barLineChart{                         metric "Active Write Clients"                         axisYUnit Unit.REGULAR                     },                 ])             },             widgetGroup {                 name "Read Clients Waiting"                 widgets ([                     balanceGauge{metric = "Read Clients Waiting"},                     barLineChart{                         metric "Read Clients Waiting"                         axisYUnit Unit.REGULAR                     },                 ])             },          widgetGroup {                 name "Write Clients Waiting"                 widgets ([                     balanceGauge{metric = "Write Clients Waiting"},                     barLineChart{                             metric "Write Clients Waiting"                             axisYUnit Unit.REGULAR                     },                 ])             }         ])     }
