WebSphere Real Time perspective

Unusual or exceptional aspects of WebSphere® Real Time application performance might be indicated by outliers. This perspective helps you identify and analyze trace information about events that might appear inconsistent with expected application behavior.

Health Center gives you the tools required to:
  • Identify outlier events.
  • Filter trace information to highlight outlier events.
  • Present outlier information in a timeline or histogram view.
The WebSphere Real Time perspective within Health Center enables you to answer questions about application performance, such as:
  • During an application run, how often did a specific operation complete on schedule?
  • Did any instance of the operation take a different amount of time to complete, in comparison to other instances?
  • What are the maximum, minimum, and mean times required to complete an operation?
  • What is the key factor - the "determinism factor" - affecting the performance of the operation?

The WebSphere Real Time perspective is supported when Health Center connects to applications running on the WebSphere Real Time versions specified in Platform requirements.

When Health Center detects that you are connecting to a WebSphere Real Time application, the perspective is enabled automatically. If you attempt to use the perspective while not connected to a WebSphere Real Time application, a warning message is displayed in the status bar, or the appropriate view window.

If no data is available for a view, a message reports the problem in the window. Common causes of data not being available include:
  • The selected trace event is not enabled on the target application.
  • No target events occurred while the trace was running.
