Prisma SD-WAN Application Insights
The Prisma SD-WAN Application Insights dashboard identifies underperforming applications and provides health scores, traffic analysis, and TCP connection statistics across your sites.

The Applications widget identifies underperforming applications and displays their health scores, lists applications with poor health scores for your tenant, and
plots the average health score over the last 3 hours in 5-minute
intervals.
Select to view the Applications screen.
Application Health Distribution—The distribution of Good,
Fair, and Poor Applications
for a given tenant.
Application Health Distribution Over Time—The Time series graph of Application
Health Distribution Over Time displays the Good,
Fair, and Poor Applications
for a given tenant. The time-series graph should be computed and refreshed based
on the selected duration. For example, supported durations are 1 hour, 3 hours,
one day, seven days, 30 days, and 90 days and the interval is 1 minute, 5
minutes, 1 hour, and one day, respectively.
Applications—The Applications list/table list all the Applications details such
as Name, Application Profile, Health Score, Impacted Sites, Traffic Volume,
Init/Failure, and Transaction/Failure. When you click the Application Name, you
can see the individual App Details on a new page.
Bandwidth Utilization—The
Bandwidth Utilization
chart displays the amount of bandwidth utilized on a trail in a network. Use the
chart to identify WAN congestion in a network that may hinder application
performance.
New Flows—The New Flows chart displays new TCP and UDP flows for an application,
a specific set of applications, or all applications for a given period. A TCP
flow is considered a new flow when it sees the first SYN packet. A UDP flow is
considered a new flow when it sees the first UDP packet in either direction. A
flow is a sequence of packets in both directions identified by the source and
destination IP, source and destination port, and the protocol.
The New Flows charts are used to analyze a site in terms of connections per
second and monitor any unlikely increase in the number of flows for a particular
application, such as DNS or any critical application, which could be a sign of
malicious activity.
TCP Connection Stats—The
TCP Connection Stats
displays the data related to the TCP connection metrics in the selected time
range and includes various metrics.
You can view TCP Application Health Distribution Over Time and
Application Health Distribution only with WCR license.
You can click the Time Series chart to view application details in the TCP Apps tab. To return to the original view after drilling down, click the Reset icon in the top-right corner of the
TCP Application Health Distribution Over Time chart. The reset icon restores the view based on global filters. The screen also displays the date and time for the data you are viewing.
The application's health score is assessed per path, focusing on metrics such as
application RTT and packet loss. Among these metrics, RTT is predominant in determining
the health score. Additionally, packet loss within the path can impact the application's
performance, enhancing the accuracy of our health evaluation.
Click the number under the Paths column to view path-level information on the Path Detail
page. The Path Detail page includes information for
Application Health Score for Application and Site and
Statistics Data aggregated at the Application and Site level.
You can view detailed information by clicking App Details or
Links Details, which opens the Activity
chart in a new browser tab.
