Component tracing

For component trace information about components, look in the third column of the table to see whether IBM® has provided tracing for the component you are interested in. If IBM has provided tracing, the table contains the trace name for that component. See component trace in z/OS MVS Diagnosis: Tools and Service Aids for information about requesting and formatting the component trace.
