Using the Protocol Monitor

The protocol monitor displays information for every session that is currently being processed. Depending on
the number of protocols monitored, and the number of sessions in progress, a significant amount of data is
generated. It is highly recommended that logging be enabled on your terminal client in order to capture all of
the information that is generated.
Refer also to
protocol and monitor subscriber commands.
