NetConfig

Whether to save tracing information to the tracing database is configurable per thread. NetConfig uses the SAVETRACING sub-key for the SAVEMSGS key:

SAVETRACING specifies if saving of tracing information is enabled for this thread. If this key is "0," or missing, then message tracing is disabled for this thread.

If SAVETRACING is set for a thread, then all traceable actions for messages owned by that thread are recorded in the tracing database. Additionally, a message-level metadata flag is set for the message. This continues to be traced even as it moves through other threads that may not have SAVETRACING set.

If SAVETRACING is not set, then no actions under that thread are recorded unless the individual message’s tracing flag is set.
