- In the footer of Dev Studio, click the Tracer icon.
- On the Tracer toolbar, click Settings.
- In the Tracer Settings window, in the Events to
trace section, select check boxes of events that you want to include in the
- To trace when an event starts, select the check box in the Start column.
- To trace when an even ends, select the check box in the End column.
- In the Break conditions section, select the conditions under which
you want the Tracer to pause processing:
- To pause processing on the first Java exception, select Exception.
- To pause processing when a step ends with a Fail status in the pxMethodStatus property value, select Fail Status.
- To pause processing when a step ends with a Warn status in the pxMethodStatus property value, select Warn Status.
- In the General options section, select the options that determine
the quantity of output in specific conditions:
- To include the Java class details from those properties in the Tracer output, if
processing has properties of mode Java Pages, select Expand Java
This option might significantly slow processing.
- To capture the status of local variables for Begin and End events of activities
and their steps, select Local Variables. Tracer creates an output
row each time the system sets the value of a local variable in an activity.
For local variables with a value of Java null, the Tracer output displays the string null – No Value for the value of the local variable.
- To reduce the performance impact by limiting the amount of clipboard detail for each row in the Tracer window, select Abbreviate Events.
- To include the Java class details from those properties in the Tracer output, if processing has properties of mode Java Pages, select Expand Java Pages.
- In the Event types to trace section, select event types that you want the Tracer to monitor.
- Optional: To add additional event types, in the Event Type field, enter the event type, and then click Add.
- In the Rulesets to trace section, select the rulesets that you want to trace.
- Optional: To trace additional pages, in the Pages to trace section, in the
Page name field, enter a page name, and then click
While the Tracer session runs, the Tracer watches the pages that you add. If the Tracer locates the pages, links to their content display in the Properties on Page window when you open an event from the Tracer output.
The option to add pages is unavailable if you select Abbreviate Events in the General options section.
- In the User interface section, in the Max Trace Events to Display field, enter the number of trace events to display in the output.
- Click OK.
- Tracer events to trace
You can select the following events to trace in the Tracer Settings dialog box. When selected, the tracer output includes these events. Events are most relevant for debugging activities rather than flows or declarative rules.
- Tracer event types to trace
You can trace the progress of various events that occur in the system by selecting event types to trace in the Tracer Settings dialog box. Examples of rules that produce events are flows, declarative rules, and decision trees rules. You can also trace events related to services and database operations.
- Rulesets to trace
You can select the rulesets to trace in the Tracer Settings dialog box. The dialog box lists all of the rulesets that you can access, in the order they appear in your ruleset list, based on your access group and other sources.
- Reducing Tracer event output
You can reduce the amount of clipboard detail that is sent to the Tracer by using the Abbreviate Events option. Reducing the amount of output improves the performance of the requestor session that is being traced so that elapsed time statistics during tracing are closer to the normal values, that is, the values when processing is not being traced.
- Setting the number of lines to display in Tracer
You can change the number of lines that are displayed in the Tracer window to manage network and workstation load. By default, the Tracer displays the 500 most recent trace lines. You can set a higher value, which requires additional workstation memory. If you only want to view Tracer output as an XML file and save it to your local system, set the number of lines to display to zero (0) to reduce the network and workstation load.
- Adjusting the buffer size of the Tracer header
You can adjust the buffer size of the Tracer header to increase the limit for unprocessed events. By default, the system saves up to 50,000 items for unprocessed events during a Tracer operation. If the buffer exceeds this limit, Tracer processing ends.
