[Janet Post]

WOW!!!

Thanks Patrick!  I will definitely use this tool!

(and I fixed the -1 thing.  Good catch.)

Hi,

It just means that embeded perl doesn't support your script. You can use the
"mini_epn" utility found in the /contrib directory of Nagios to test it : 

# ./mini_epn 
Enter file name: check_apache.pl
embedded perl ran check_apache.pl with error Variable "$url" is not imported
at (eval 2) line 149.
        ...propagated at (eval 1) line 110.


You must use "use strict" option and check your script works with this
before using embeded perl
(http://nagios.sourceforge.net/docs/2_0/embeddedperl.html)

By the way, "UNKNOWN" has a retrun value of 3, not -1.

Patrick

Thanks Robert!  That worked like a charm.  

Except, now I am curious as to why some scripts need to have perl executed
directly and not others.  Any ideas?

Try changing the Nagios command object to execute perl directly rather than
just calling the script:

define command {
command_name    check_apache_threads
command_line    /usr/bin/perl $USER1$/check_apache.pl
}

and see if that fixes the problem.
