Topic Name

The routines that write messages are called trace topics. Trace topics correspond to subroutines invoked by a subsystem, or to some type of major functionality provided by an application. Every subsystem and application has its own set of trace topics. This criteria allows you to specify topics to filter by.

To filter by topic name:

  1. Select an entry in the All Topics list.

About [System]:[System Topic]

The first choice in the All Topics list is [System]:[System Topic]. It configures the filter to look for messages that were generated by the trace code itself. Items such as "Start Tracing" messages fall into this category. These "automatic topics" are generated by the trace system before the application has initialized its topics. For that reason there is no application-specific topic that could be used for "Start Tracing" messages. If the log contains corrupt messages, they show up as System topics too, because the messages are too corrupt to determine their proper topic.

  1. Click Add.

  2. Repeat steps 1-2 to filter on additional topic names.

  3. Click OK.
