Linux/Unix script monitor issue

Question

I have created test script for Linux/Unix script APM template to see how exit status impact on script status. following is my sample script

#!/usr/bin/perl
use strict;
if ( 0 == 0 ){
print "Message.1: Available memory
";
print "Statistic.1: 99
";
}
exit 0;

I tried following exit values to see how orion changing status.Why its showing Unknown on other exit code ?

exit 0;   =  status Unknown

exit 1;   =  status Down

exit 2;   = status Unknown

exit 3;   =  status Unknown

exit 4;   =  status Unknown

exit 5;   =  status Unknown

Valid exit codes and their statuses are listed below. If your results differ I recommend testing some of the scripts included in APM to see if they work. If they too exhibit the same behavior as you're seeing above I recommend you open a case with support. If the out of the box scripts work, the problem is likely with your script. While I see no obvious issues with your script I haven't tested it personally. I would recommend using the out-of-box templates as examples.  More information on Linux/Unix script monitors can be found in the APM administrators guide.
