CloudExpress

Use the CloudExpress dashboard to view the performance of cloud applications for which you have enabled CloudExpress service and to manage the CloudExpress configuration.

CloudExpress service calculates a performance value called the Viptela Quality of Experience (vQoE). The vQoE value weighs loss and latency using a formula customized for each application. For instance, email applications tolerate latency better than video applications do, and video applications tolerate loss better than email does. The vQoE value ranges from zero to ten, with zero being the worst quality and ten being the best.

Screen Elements

  • Filter criteria—Sort options drop-down and Search box, for a Contains or Match string.
  • Application panes—Display performance of individual applications.
  • Legend—Indicates quality of experience levels for cloud applications.
  • Manage CloudExpress—To add or remove applications and DIA sites in the CloudExpress configuration.

View Application Panes

Each pane in the CloudExpress dashboard displays the performance of one cloud application. To display only certain applications, select sort options in the drop-down or type a string in the Search box.

Each pane displays the number of devices accessing the application and the connection quality for those devices. These devices are always vEdge routers.

  • The top status bar displays red for devices experiencing bad quality.
  • The middle status bar displays yellow for devices experiencing average quality.
  • The lowest status bar displays green for devices experiencing good quality.

The number to the right of each status bar indicates how many devices are experiencing that level of quality.

View Details about an Application

  1. Click in the application's dashboard pane. A table of sites accessing the application displays.
  2. Click a graph icon in the vQoE Score column to display vQoE history for that site.
    • Click the time duration links to adjust the data the chart displays.
    • Hover over a point on the chart to display vQoE details for that point in time.
