The Application Sunburst widget is used to identify poor performing applications.

It Shows application activity and performance impact for the selected location in a sunburst.

When you select a location, the widget shows the applications in a sunburst presentation indicating "if" and "how much" an application is affected with different colors. The sunburst provides an intuitive way of determining if only a single application in the location is affected or if all applications are affected.


If only a "all applications" are affected it is an indication of a network related issue where as it is more likely that the issue is related to the application server if  only a "single application" is affected.

The user can identify where the problem lies within the organization by looking at affected applications(s) in the selected time frame. You can expand or collapse the root node of the tree as well as children nodes in order to identify the specific application.

The sunburst presentation is based on the activity for the selected location. The size of the Applications in each ring is determined by the number of computers accessing the application, known as 'online computers'. The applications are colored based on how many computers experience degraded performance on the application:

  • Green: Less than 10% of the online computers are affected
  • Yellow: 10-20% of the online computers are affected
  • Orange: 20-30% of the online computers are affected
  • Red: More than 30% of the online computers are affected

You can view the number of affected applications and impact details such as how big the threshold violation was by placing your cursor over a specific application.

 When referring to an Application, how do you define "Online" and "Affected"?

Multiple events are triggered based on the data reported by the PerformanceGuard Agent. If the agent reports a connection to a defined application an "Application Online Event" is triggered to keep track of which computers are connected to which applications. If the reported response times exceed a defined threshold, then an another event is triggered. This allows PG to determine the impact ratio of computers experiencing bad response times and the computers that are connected to the application, which we refer as to "Affected".

Set Up the Widget


Select what You Want to View

Your PerformanceGuard administrator has typically set up the widget to view the affected applications.

When that's the case, you can simply use the Location menu in the top part of the dashboard to view the number of affected computers for selected Time Period.
