[Nagios-users] Defining passive checks
I'm a long-time user of Nagios with active checks. Today I started using
passive checks with NSCA and I'm having a problem.
The documentation states A service must be defined in Nagios before you
can submit passive check results for it.
I defined a config block like this, to define a service for the Oracle
service that I want to monitor passively - omitting the check_command
directive.
define service {
service_descriptionOracle
host_name oddjob.resnet.bris.ac.uk
useresnet-service
}
But running nagios -v gives this output:
Error: Service description, host name, or check command is NULL
Error: Could not register service (config file
'/etc/nagios/nagios_service.cfg', starting on line 8618)
Error processing object config files!
So what's the approved way of defining a service without specifying a
command for active checks?
Thanks,
Jonathan

This should work, also with self-signed certs. Doing this in my Nagios config as well. Whats the check_http command you're launching? What's the error message?

The approved way is that you can't because it remains a service
definition, however the command
can be dummy , although it must be defined.
The command definition however is obliviated by using :
active_checks_enabled 0
passive_checks_enabled 1
Sometimes for check_command check-host-alive is being used, this avoids
long outstaniding stale data
for the specific passive service definition.

[Nagios-users] Issues with check_by_ssh
Hi list,
I have some issues with the plugin check_by_ssh. In particular, there is
one error:
When I run a shell script located in another server, from the Nagios server

But, by any strange reason, when I configure the check for Nagios presents
the results in its interface, I have the error:

I have made the ssh authorization keys in both servers (Nagios and Xen), I
configured the users, permissions,etc. And I can't to do this work it.

Re: [Nagios-users] Issues with check_by_ssh
Hi,
since the plugin is executed as user nagios, check if the command (including
all params) works as user nagios (or whatever user id it is running as)
Problem could be:
1) Nagios user can’t read the ssh key file as it resides in root
directory
2) Or it can’t write the ~nagios/.ssh/known_hosts file
PS: In general it is not a good practice to use root ssh key for nagios
commands
I would suggest to create a ssh key for nagios user and place it in
nagios home or a place where nagios user has access to
Regards,
bp

Re: [Nagios-users] Issues with check_by_ssh
Its highly unlikely that the Nagios user has permissions to use a key owned
by root, and thats a good thing.

Re: [Nagios-users] Issues with check_by_ssh
Hi friends,
Also, I've been doing some tests with the user nagios but I obteined the
same result.
In this case, I tried in the context of the user Nagios but it works
through the terminal:
*nagios@nagioserver:~$ /usr/lib/nagios/plugins/check_by_ssh -l nagios -H
172.16.31.2 -C /usr/lib/nagios/plugins/check_Xencpu -i
/var/lib/nagios/.ssh/id_rsa*
*“OK:CPU%= 10”*
If I set up my definition of the command:
*#Check Hypervisor*
*define service{*
*use generic-service*
*host_name ORLANDO*
*service_description Hypervisor CPU*
*check_command
check_by_ssh_xentop!nagios!172.16.31.2!/usr/lib/nagios/plugins/check_Xencpu!/var/lib/nagios/.ssh/id_rsa!
*
*}*
But, the result is not correct:
