[Nagiosplug-devel] Nagios plugin work in command, but not in Nagios

[Fallsen, Tommy]

Hi
I've written a little perl script to report if anything is wrong with
the Metadevices on a Solaris Server.
Problem is that the script works perfectly in command mode, debugging
show that it
print some text and exit with exit $ERRORS{'CRITICAL'}; when metastat
report error. However in Nagios all i get
is OK and no output. 

Here is the script, please note that i learned perl while creating this,
so the problem might be the script.
I think its made after the criterias in Nagios plug-in development
guidelines.

sub print_help {
        print "\n\n";
        print "This plugin checks Disksuite status on a remote Solaris
system \n\n";
