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
