Identifies the top applications which are not performing well. The
Applications widget displays the determined health score of
all poor applications, lists poor applications for a tenant based on health score, and
plots the average health score of poor applications for the last 3 hours in 5 minutes
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 on the Time Series chart to see the details of those
applications in the TCP Apps tab. Then, when drilling down on the
chart, click on the Reset icon (on the top right corner of the
TCP Application Health Distribution Over Time chart). You can
always return to the original view per global filters by clicking on the reset icon. In
addition, the screen shows the message at which date and time you are viewing the
details.
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 on the number under the Paths column from the application
details to see path-level information, which leads to 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 on App Details and
Links Details links, which will lead you to the Activity
chart in a new browser tab.
