To maintain the quality of your application, you can use the Tracer window to interact with Tracer results. Each row in the window represents an event. The Tracer records selected events from the rule executions, database operations, and other event types that you selected when you configured the Tracer.

1. In the footer of Dev Studio, click the Tracer icon.
2. In the Tracer window, analyze the Tracer output:
   • To learn more about the event and view a Java stack trace if an exception occurred, click the value in the Line, Rule#, or Step column.
   • To view the properties that were on the step page when the step began, click the value in the Step Page column.
   • To open the corresponding rule, click the value in the Name column.
   • To view the contents of the parameter page, click the value in the Line column, and then click Parameter Page Name.
   • To view the contents of the primary page, click the value in the Line column, click Primary Page Name.

• Tracer results window

  The header row of the tracer results window contains the Pega node hash and computer name. For cluster-wide tracing of service rules, the tracer displays a separate section for each node that reported events.
