I've solved my problem using several scripts based on check_grep 
(nagios-of-plugins-0.8.3.tar.gz). Two for the amcheck (one for the label 
check and one for the connection check) and one for amstatus.
In order to use nsca, you have to do a thing like this:

- a config file config.pl (usefull if you have more than one check with 
nsca, useless if not):

#!/usr/bin/perl
$nsca_host="@ip";
$config="/etc/nagios/send_nsca.cfg";
$send_nsca="/usr/sbin/send_nsca -c $config -H $nsca_host";

- a perl script amstatus.pl (for example):

#!/usr/bin/perl
require "/usr/lib/nagios/plugins/config.pl";

$cmd="/usr/lib/nagios/plugins/amstatus.sh";
$hosts="backup";
$service="backup_check_status";   # you have to create this service on 
the services conf file / oreon interface
$RESULT=`$cmd`;

if ($RESULT =~ /OK/) { $code = 0; }
if ($RESULT =~ /WARNING/) { $code = 1; }
if ($RESULT =~ /CRITICAL/) { $code = 2; }

open(SEND,"|$send_nsca") || die "Could not run $send_nsca: $!\n";
print SEND "$hosts\t$service\t$code\t$RESULT\n";
close SEND;

- a bash script amstatus.sh with the command to use:

#!/bin/sh
/usr/lib/nagios/plugins/check_grep "dumped          :  52" --command 
'amstatus DayliSet'  # 52 if the number of entries in my disklist, so 
you'll have to change this to suit your needs.


Then, add the amstatus.pl to the crontab


Hope this help


Thomas
