View Application Performance with Cloud OnRamp for SaaS

Cloud OnRamp for SaaS (formerly called 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, and video applications tolerate loss better than email applications. The vQoE value ranges from zero to ten, with zero being the worst quality and ten being the best. Cloud OnRamp for SaaS computes vQoE values for applications and paths, and then assigns applications to the paths that best match their vQoE value. Cloud OnRamp for SaaS periodically recalculates vQoE values for paths to ensure ongoing optimal application performance.

In vManage NMS, select the Configuration ► CloudExpress screen, or click the CloudExpress icon in the title bar. The CloudExpress Dashboard displays the performance of each cloud application in a separate pane.

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 experience 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.
