Introduction to the WebSphere Real Time perspective

The WebSphere® Real Time perspective (WRTP) helps you trace specific WebSphere Real Time (WRT) events over time.

The perspective helps you identify unusual or exceptional events that might occur when you run a WRT application. The trace information can be presented in various ways, including linear or logarithmic scales, and histograms. WRTP provides some pre-defined trace point views that are especially helpful.

Example traces include:
Each view in WRTP represents a specific JVM or application operation. A view includes the following information:

The predefined trace point views are supplied as a resource bundle, and are automatically provided within the Health Center GUI. You can create and customize more views, and make them available to Health Center by adding them to a custom view store.

Data about trace points is recorded to help with the analysis. For example, each time the application reaches an entry trace point, the operation start time is recorded. Similarly, when the corresponding exit point is reached, the time is recorded and the total time to perform the operation is calculated. This data is used for graphical displays of information, and also for determinism calculations.

Within the WRTP, you can choose from predefined or customized views. Predefined views include: Customized views are described in Customizing the WebSphere Real Time perspective.
