From the Overview Dashboard page, click Applications to navigate to the Application Dashboard. Alternatively, you can click View Details or Applications in the Applications widget.
The Application Dashboard page displays information on how different applications are performing across an overlay for all sites, and also for a single
site.
The Application Dashboard gives an overview of Application performance (QoE) for all applications across an overlay and across all sites, and compares
it to other metrics such as overall bandwidth and bandwidth increase.
The Application Dashboard represents the performance metrics in these widgets:
You can also view the metrics in a tabular format. With the tabular format, you can search and view the metrics for any application.
Application Experience
The Application Experience widget displays utilization details, the number of applications that were good, fair, poor, and
unknown by counts, and the total volume of traffic. An accordion chart shows the top applications by usage with the color
indicating the application health in terms of QoE score. This helps draw attention to the most critical application performance
issues. Applications with an unknown QoE score are represented in gray.
To view more information about an application, hover the mouse pointer over a specific application.
Application Trend Analysis
Click Application Trend Analysis in the Application Experience widget to launch the Application Trend Analysis widget to view trends of applications for a
selected time period in the form of charts.
With the Application Trend Analysis widget you can visualize trends of applications from the following perspectives:
-
Plot of numbers of Good/Fair/Poor applications by QoE over a selected time-interval.
-
QoE trend-line of top five applications (by bandwidth) over a selected time-interval.
-
Ability to specify a custom list from the table of applications, where you can select or deselect applications to view information.
Click a trend-line to view more details about a selected application. You can view the top applications by bandwidth usage,
ordered High to Low. Hover the mouse pointer on the graph to see the performance measure values for the applications at a
particular time.
Click an individual application block in the accordion chart to navigate to the Application 360 page to view more detailed
information about the application you selected.
Application 360
Click an application in the Application Experience widget to navigate to the Application 360 page. Alternatively, you can click an application in the Trending Application widget, or on an application in the page elements
that are listed in the table below, or on any application in the Application widget in the Overview Summary Dashboard to retrieve
the Application 360 page.
The Application 360 page gives you a view of a single application performance across all sites with the capability to further drill down to in-depth
details about an application at a single site and tunnel.
From the Application 360 page, you can visualize how the QoE for a specific application has changed over a selected time period. You can use the Application 360 page to do the following:
-
Compare an application’s performance across each site, showing aggregated counts of Good/Fair/Poor sites on a map view.
-
View the network path taken by an application across time for a single site.
-
View metrics of applications across an overlay corresponding to various network Key Performance Indicators (KPI), with the
ability to select specific sites to view loss, latency, jitter, users, and usage per site.
Note
|
The Application 360 page for a single site does not present statistics for applications flowing through a Direct Internet Access (DIA) exit for
Cisco vEdge devices.

Note
|
To trace paths and view underlay path information in Cisco SD-WAN Analytics, enable the underlay measurement and tracing services (UMTS) feature in Cisco SD-WAN Manager, and use a Cisco SD-WAN Manager version Cisco vManage Release 20.10.1 or later.

Sankey Chart
A Sankey chart provides more details about application flows across various Cisco Catalyst SD-WAN tunnels and DIA paths within a single site, and aids in understanding the health of the application over these tunnels, which
terminate at the remote sites.
To view a Sankey chart, choose a single site, and then choose an application. Click the App Flow tab.
The left side of the chart displays information about the local site and color, followed by the QoE score. The right side
displays information about the remote site and its color. The size of each link indicates the cumulative usage volume of the
tunnel extending from the local site to the remote site.
By default, the Site drop-down list showcases the top five sites with the highest QoE scores. The chart aggregates and displays this site information.
Furthermore, you can select and display information for up to six sites from the drop-down list.
The Sankey chart displays information for both Cisco Catalyst SD-WAN tunnels and DIA paths. For the DIA path, the local color represents the interface name, while the remote site is denoted
as SaaS. A flow without remote color and site information represents a DIA path. The chart also identifies any unknown QoE paths
as gray paths.
Click a node to highlight all relevant tunnel paths passing through that node. Hover the mouse pointer over the individual
sections to view additional information about the volume of usage traffic. The central link classifies the path's quality,
categorizing it as good, fair, poor, or unknown.

QoE Distribution by Application Classes
The QoE Distribution by Application Classes widget displays the applications against different classes. Application classes
are broad categories that are used to group applications based on their behavior and network performance requirements. The
plot helps identify systemic network and overlay issues that can cause specific classes of applications to perform poorly
in the overlay network. An inconsistent ratio of Poor/Fair/Good/unknown for a specific traffic class could indicate possible
policy misconfiguration for that application in the overlay.
Trending Applications
The Trending Applications widget lets you compare top applications that have significant rise and drop in their measured QoE score, usage, loss, latency.
Applications
The Applications widget displays a table of all applications in an overlay. Applications that have an unknown QoE score are represented with
a hyphen.
