Formerly known as Application Impact for Computers

The Computer Bubble Chart Widget makes it easy to determine if a selected computer has had performance problems. If it has, the widget makes it easy to see exactly which kinds of problems the computer has had, and exactly when they happened.

This widget is similar to the "Application Impact for Locations" with the focus on showing a timeline for all applications accessed by the computer within the selected time period.

The widget looks at the number of the applications that are affected by triggered events e.g. with longer response time or availability for the specified computer and displays them as a bubble markers on a timelime.

Remember what an event is? It's a threshold violation, for example a response time that isn't acceptable. When an event happens, the widget looks at how many online applications are affected by the events, and the bubbles then adjust color accordingly.


These bubbles change their color according to the severity of events during 15 min prior:

  •   Green bubble: Shows an Online activity
  •   Yellow bubble: Minor Severity (at least 1 event between 1-7 minutes)
  •   Orange bubble: Major Severity (at least 1 event between 1-7 and 8-13 minutes)
  •   Red bubble: Critical Severity (at least 1 event between 1-7, 8-13 and 14-15 minutes)


 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".
 Why is the yellow bubbles sometimes unclickable?

The Computer Bubble Chart looks at the density of events during 15 min prior. If there is no events, but a density greater than 0, you'll have a yellow unclickable bubble.


Set Up the Widget

You have to define an application before you can set up the widget. PerformanceGuard automatically creates an Application Online event when an application has been created.
Technically, your administrator sets up PerformanceGuard applications to define this.
You must define Event Rules in Event Management before adding the widget on your dashboard.

  • Your PerformanceGuard administrator has predefined Event rules i.e. select ADMINISTRATION > Event Management > Event Rules (or create a new Event Rule).
    • For Client/Server applications:
      • Response Time, Availability and Application Online
    • For Web applications:
      • Response Time, Availability and Application Online

How does PerformanceGuard determine if a computer is affected or not?  PerformanceGuard looks at the performance data it receives from agents installed on your organization's computers. It continuously evaluates the number of computers affected by events over a period.
PerformanceGuard comes with a number of built-in event rules, so your administrator doesn't necessarily have to set up event rules of his own.

Select what You Want to View

Your PerformanceGuard administrator has typically set up the widget to view the timeline.
When that's the case, you can simply use the Computers menu in the top part of the dashboard to view the number of affected computers for selected Time Period.
You can view the details of events - simply click on it. This will display information about:

  1. Event Timestamp: View when each event happened as it displays the date and exact time interval when the event occurred.
  2. Event Description: See how great the threshold violation was as it displays the average response time / availability for the selected computer that has exceeded it's set limit.
 Bubbles only show an online application activity and thus does not show any information regards to events.
