Applications

Top Bar

• Bandwidth—Displays bandwidth utilization for application families.
• Performance—Displays Viptela Quality of Experience (vQoE) values for application families. The vQoE value ranges from zero to ten, with zero being the worst performance and ten being the best. vQoE calculates this value based on latency, loss, and jitter, customizing the calculation for each application.
• Anomaly—Displays application families using more bandwidth than their baseline.
• Time Period—Click a predefined or custom time period for which to display data.

Display Bandwidth Utilization

To display bandwidth utilization for application families:

1. Click Bandwidth.
2. Click the Filter icon to select a specific application family to view.
3. Click the PDF icon to open a PDF version of the chart in a new tab.
4. Hover over an item in any chart to open a hover box with details about that item.
5. Select a view: By Summary, By Time, or By Sites:
   • By Summary displays a summary by application family. Click an application family to display applications in that family. Click an application to see that application's bandwidth utilization over time. Click a point on the timeline to see that application's bandwidth utilization by site. Click a site to see flows for that application at that site.
   • By Time displays a timeline of application family bandwidth utilization. Click an application family to display utilization for the applications in that family. Click an application to display utilization at each site running the application. Click a site to display flows for that application at that site.
   • By Sites displays bandwidth utilization on each vEdge router. Click a site to display a timeline of application family bandwidth utilization at that site. Click an application family to display utilization for applications in that family at that time. Click an application to display flows for that application at that site.

Display vQoE Values

To display vQoE values for each application family:

1. Click Performance.
2. Click the Filter icon to select a specific application family to view.
3. Click the PDF icon to open a PDF version of the chart in a new tab.
4. Hover over an application family in the chart to open a hover box with details for that application family.
5. Click an application family to display average latency, loss, jitter, and vQoE for each application in that family: 
   1. Click an application to display that application's performance on each device in the tunnel.
   2. Click a device to display an hourly summary of that application on that device.

Display Deviations from Baseline Utilization

vAnalytics platform computes daily averages and standard deviations for application families at every site in a rolling window of seven days. An anomaly occurs if an application family's bandwidth utilization exceeds the average plus two times the standard deviation.

To display deviations from baseline values of bandwidth utilization for application families:

1. Click Anomaly.
2. Click the Filter icon to select a specific application family to view.
3. Click the PDF icon to open a PDF version of the chart in a new tab.
4. Hover over an application family in the chart to open a hover box with details for that application family.
5. Click a site to see a timeline of anomalies for that site.
6. Click an hour on the timeline to see anomalous behavior of individual applications in that hour.
