Use the logging preferences to specify the MIB Manager log file directory, and to set the default message level.
To set the directory preferences, click 
Preferences or, from the main menu,
click , and then from the left pane of the Preferences window,
click Logging.
- In the Log directory field, specify where the application log file is written. The default location is NCHOME/omnibus/log.
- In the Default Message Level field, specify
the application's default message level. You can also use the Edit menu
to change the default message logging level. The message level is
valid from when the application is first started until when the application
is shutdown, unless it is changed using the Edit menu. Note: Changing the message level in the Default Message Level field does not change the current message level of the application. It only affects the message level that was initially set when the application was first started (the default message level). To avoid generating large log files, set the default message level to warn.
