Trouble with embedded perl: nagios keeps forking perl plugins

[Nicolás Alen]

Dear Stanley,

Thank you very much for your reply.
Nag installation seems correct. I'll put some examples anyway:



Nagios binary:

=================================================================
# ./nagios -m

Nagios 1.2

* Embedded Perl compiler (With caching)
=================================================================



An example perl command on checkcommands.cfg:

=================================================================
define command {
command_name                   check_ping
command_line                   $USER1$/check_ping.pl $HOSTADDRESS$ $ARG1$
$ARG2$ $ARG3$ $ARG4$ $ARG5$
}
=================================================================



Part of the code...

=================================================================
#!/bin/perl -w

use strict;
use lib "/usr/local/nagios/libexec";
use utils qw(%ERRORS $TIMEOUT);
use Data::Dump qw(dump);

sub print_usage
{
        print "usage: check_ping.pl host wpl cpl wrta crta [packets]\n";
        exit $ERRORS{"UNKNOWN"};
}

print_usage() if (@ARGV < 5);

$SIG{'ALRM'} = sub
{
        print "ERROR: Alarm signal (Nagios time-out)\n";
        exit $ERRORS{"UNKNOWN"};
};

alarm($TIMEOUT);
=================================================================


>> Do your plugins contain a shebang line ?

Yes. It was #!/usr/bin/perl before you asked, but still I see Nag forking
and executing perl to run the plugins: 

# ps axuwww | grep perl | grep ping
nagios   21211  3.0  0.1  3008 1648 ?        R    01:21   0:00 /bin/perl -w
/usr/local/nagios/libexec/check_ping.pl 200.32.5.224 20 50 300.0 1000.0


>> The only way of nailing this, or any plugin/Nag problem,

Didn't find find anything useful apart from a wrong path to my host-perfdata
log :/ 


Do you think I should try nagios 2 for a chage?
This is somehow silly, but do I have to include some special code on my perl
plugs? 



>> Acres of HTML deleted; please don't do this.
Sorry! Won't do it again.


Thank you very much again!!

Nicolás Alen.






Yours sincerely.
