Formerly known as Application Performance Overview

The Application Chart widget can show the availability and response times of your organization's business-critical applications. It can also show how many sessions use the applications, and how many requests the applications get.

The widget can show this information about any application—including web-based activities—that your PerformanceGuard administrator has defined.

You can use the widget to, for example, find out if individual computers or locations have availability issues or longer response times than others. This in turn can help you identify if network problems cause an application to work slowly when particular colleagues use it.

Select what You Want to View

Your PerformanceGuard administrator has typically set up the widget to show information about one or more metrics (for example availability and response time) for one or more applications.
When that's the case, you can simply use the Computers and Locations menus in the top part of the dashboard to view how the application performs when a particular computer or location uses it.

You can select multiple computers and locations to compare how an application performs across computers and locations.

When you use the Locations menu, there's a search field that you can use to search for locations.

In some cases your administrator may let you select applications and application performance metrics yourself. When that's the case, you can select the exact information you require from the Applications and Application performance metrics menus in the top part of the dashboard.

When is something considered to be available?

To answer this we need to look at response times: If response times are so long that use of a service, website, transaction or similar becomes impossible, PerformanceGuard considers the service, etc. to be unavailable. By default, PerformanceGuard loses its patience with a service, etc. if it hasn't responded within 500,000 milliseconds (that's a little more than eight minutes).

Everything that's not unavailable, is considered by PerformanceGuard to be available. So, if you see that a service has been 100% available during the last week, it means that it has not exceeded the acceptable response time limit during the last week.

Set Up the Widget

You can only do this if you're a PerformanceGuard administrator.

Before you set up the widget, you need to find out if you have defined the applications that you want to be able to view in the widget.
When you're ready to add the widget to a dashboard, you simply select the required information in the widget setup dialog's Applications and Application performance metrics menus.

Many applications and metrics in the same widget can be confusing. It's better to use multiple widgets with a few items in each.
