That "No Output" Error

Hello all,

I have been googling for the last week for this 'No Output' problem. Sadly
I can't find any helpful solution so I am bringing this up to the list. I
am running Nagios 1.2 to monitor routers and Unix/Linux servers for
sometime now without any issue. But a few days ago, I added an entry to my
config files to monitor a Windows server. The only correct thing I can see
is that it sees that the server is up. Other than that, all I see are 'No
output' critical errors. The other thing is that I see a valid output
using command line.

Here is my entry in the checkcommands.cfg file:
define command{
        command_name    check_win_mem
        command_line    /usr/lib/nagios/plugins/check_win_mem.pl
$HOSTADDRESS$ $ARG1$ $ARG2$ $ARG3$
        }

And here is the entry in the hosts.cfg file:
define service{
        use                     check-windows-generic
        host_name               my-server
        contact_groups          windows_admin
        service_description     MEM Usage
        check_command           check_win_mem!public!50!90!
        }

When I run
/usr/lib/nagios/plugins/check_win_mem.pl <IP> <community> <warn> <crit>,
it gives me a useful output. But when it comes to the web interface, I
only see 'No output.' I know this can be done but just don't know what
else to do. I hope someone can help me out.

Thanks a heap in advance!!!


Cheers,

Edward
