B<xcatdebug> {B<levelnumber>}

=head1 DESCRIPTION

The xcatdebug command starts the xcatd daemon in Perl Debug Trace mode. It is to be used for diagnosing xCAT problems. The trace outputs the paramters passed into the xcatd subroutines, listed in the tracefiles. The tracefiles are located in /opt/xcat/share/xcat/tools/tracelevel<levelnumber>.  The amount of trace data collected varies with the levelnumber. levelnumber 0 being the least amount of trace and increasing with the number. You can add more tracelevel files to suit the problem being debugged.

You must have perl-Debug-Trace installed. 

Before running this command, you should stop xcatd on your system.
After running the command, you will have to kill all the xcatd processes and possibly the xcatdebug process.
Run ps -ef | grep xcatd and kill any processes
Run ps -ef | grep xcatdebug
