ssh and output

[Lena M]

Hello, All,

My name is Lena, and I'm new to the list.

I'm having a problem with nagios displaying output of the commands it runs over ssh. I hope you can help me solve it.

For instance, when I run the following from a command prompt of my monitoring host, I get an output:
-bash-2.05b$  /usr/bin/ssh redhat1  /usr/local/nagios/check_disk -w 3 -c 1 /dev/hda1

DISK OK [1058016 kB (20%) free on /dev/hda1]

However, nagios displays "Current Status: Unknown" and "Status information: No output!" in its web page when it runs the same command.

I tried using different ssh commands but..the same result. Both hosts have redhat 8.0 and nagios 1.1 installed. Your help will be greatly appreciated.

Here is configuration info from nagios files:

checkcommands.cfg

define command{

        command_name    ssh-2check-users

        command_line    /usr/bin/ssh redhat1 /usr/local/nagios/check_users -w 3 -c 1

        }

services.cfg

define service{

        use                             generic-service         ; Name of service template to use



        host_name                       redhat1

        service_description             FREE DISK SPACE

        is_volatile                     0

        retry_check_interval            2

        contact_groups                  redhat-admins

        notification_interval           240

        notification_period             24x7

        notification_options            w,u,c,r

        check_command                   ssh-2check-disk!80%!90%!/dev/hda1
