Filtering

Each log entry has a log_level

* SEVERE       CONSTANT PLS_INTEGER := 1 ;
* WARNING      CONSTANT PLS_INTEGER := 2 ;
* INFO         CONSTANT PLS_INTEGER := 4 ;
* VERBOSE      CONSTANT PLS_INTEGER := 5 ;
* VERY_VERBOSE CONSTANT PLS_INTEGER := 6 ;
* DEBUG        CONSTANT PLS_INTEGER := 7 ;
* TRACE        CONSTANT PLS_INTEGER := 9 ;
* NONE         CONSTANT PLS_INTEGER := 10 ;

The default logging level is 4.

The default filter level is 4.

The process level default can be changed with the begin_log with the log_level parameter:

begin_log(logfile_directory => 'tmp_dir',
          logfile_name=>'debug.log',
          log_level=>2);

In which case only messages with log_level of 2 or less will be logged.

But if it is desired to see more messages from a particular package, the filter level may changed:
