Types of Diagnostic Information
Chapter 120
These messages are displayed by the system whenever
a serious system problem is encountered.
Information from the Log File
The log file contains information about program events.
There are three different types of events about which
information is logged: problem, exception, and audit.
Each is captured to a log file that you can access to
obtain the information needed to resolve a problem.
Information from Tracing
Tracing is a means of tracking the events occurring
across a particular boundary of SNAplus2 while
SNAplus2 is running. SNAplus2 offers a wide variety
of tracing options that can be activated for diagnostic
purposes.
Information from Alerts
Standard SNA alerts are generated and transmitted to
the host. They can be viewed on the host with NetView.
The program error messages and log messages usually specify the nature
of the problem, its cause, and the recommended action, which is often
enough to help you resolve a problem. The amount of information
available to you depends on the nature of the problem and on how you
set up logging. For example:
• Program error messages are automatically displayed; they cannot be
disabled.
• Event logs indicating problems are also automatically generated and
cannot be disabled, though logging of exception event logs can be
disabled. Audit event logs are not logged unless you choose to log
them.
Tracing should only be activated when you suspect a problem. You can
then trace activity in the area that you are experiencing a problem with.
Additionally, you can control the amount and format of the tracing
information collected for you.
In addition to diagnostic information, SNAplus2 also has extensive
online help information for the following:
