Overview of TN3270 Logging
TN3270 logs messages for the following event categories:
Problem event
An abnormal event that degrades the system in a way
that is easily perceived by a user. An example is
abnormal termination of a session.
TN3270 always logs these events. You cannot choose to
disable logging of these events. By default, TN3270
logs these events to the file sna.err in the
/var/opt/tn3270 subdirectory. You can specify a
different file name in the diagnostics configuration
file record.
Exception event
The following are categories of exception events:
• Abnormal system events that degrade system
performance but are not immediately perceived by a
user. An example is a resource shortage.
• Events that do not degrade system performance but
may indicate the cause of later exceptions or
problems. An example is receiving an unexpected
message from the remote system.
You can choose to disable logging of these events by not
including the exception flag in the diagnostics
configuration file record. By default, TN3270 logs these
events to the file sna.err in the /var/opt/tn3270
subdirectory. You can specify a different file name in
the diagnostics configuration file record.
Audit event
A normal system event. An example is starting a
session.
You can choose to disable logging of these events by not
including the audit flag in the diagnostics
configuration file record. By default, TN3270 logs these
events to the file sna.aud in the /var/opt/tn3270
