CloudExpress

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

CloudExpress service calculates a value called the Viptela Quality of Experience (vQoE). The vQoE value weighs loss and latency using a formula customized for each application. For example, 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. CloudExpress service computes vQoE values for applications and paths, then assigns applications to the paths that best match their vQoE value. CloudExpress service periodically recalculates vQoE values for paths to ensure ongoing optimal application performance.

View Application Performance

Each pane in the CloudExpress dashboard displays the performance of a cloud application.

Each application pane displays the number of vEdge routers accessing the application and the quality of the connection:

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

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

View Details about an Application

  1. Click in an application's pane. vManage NMS displays a list of sites accessing the application.
  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.
