Changing error logging levels

Mail and Messaging Guide
Chapter 4, Managing mail with MMDF

You can have MMDF maintain a complete log of authorization attempts with reasons for failure or success.

By default, the MMDF Configuration Manager sets up MMDF to log fatal errors only. To change the logging level, start the Channel Administration Manager. Then:

Highlight the channel to modify.
Select Modify from the Channel menu.
Click on Log File.
Use the default log file or specify a different log file by clicking next to Select and typing the name in the ``File'' field.

Select the Log level:

 fatal errors only           Logs only fatal errors.
                             Produces a complete log
                             of authorization
                             attempts.
 temporary errors            Logs both temporary and
                             fatal errors.  Produces a
                             complete log of
                             authorization attempts.

                             interesting diagnostics
                             and errors.  Produces a
                             complete log of
                             authorization attempts.
 basic statistics            Logs some basic
                             statistics about movement
                             of messages.  Produces a
                             complete log of
                             authorization attempts.

 program trace listing       Shows a program trace
                             listing of channel
                             activity.

                             program trace listing.
 every diagnostic possible   Logs all possible
                             diagnostics.

Each level listed here logs the preceding levels. For example, Interesting diagnostics logs Fatal errors and Temporary errors as well. The last three levels are most often used by experienced administrators for analysis of MMDF configuration.

The log file's default maximum size is 1000 blocks. This value, and other log file parameters, can be modified; see the description of MCHANLOG in mmdftailor(F).
