5.2 Conditional Trace using the Web UI

Example workflows

1. To create a trace template for the workflow shown above, go to the  Web UI http://<platform host>:<web interface port>/mz/. Select Conditional Trace, and then New Template. This template is configured to set a trace template for hits on the r_1 route, and the Analysis_1 agent in the workflow named conditionalDemo.fwd.wf, with the field name Sequence. The lifetime determines the timeout of a trace to be 10000 milliseconds, the maximum number of hits in a trace is limited to 10. The unique name of the trace template is pulse2. The following line is included in the APL code in Analysis_1:

   trace(input, "Message");
