passive check (NSCA)

[mascir]

Hi All,


i found a cool tutorial on the web:

http://nagios.sourceforge.net/downlo...NSCA_Setup.pdf

i have compiled the NSCA plugin i have installed xinetd and the i followed step by step.

so, after i tested the NSCA config i have had problem with nagios.


>Configuring Nagios
>If everything is running smoothly so far, the final step would be to create the service to process your
>passive checks in Nagios. I will show how to create a standard passive check service, but as with
>everything in Nagios, it should be customized for your own needs.
>We are going to use the check_dummy as our check_command in the service we must define that
>command as well. Open up Nagios config file containing your check commands, if you are using
>minimal.cfg, this will be in here. Enter the following lines in the commands section:
define command{
command_name check_dummy
command_line $USER1$/check_dummy $ARG1$
}

done in /usr/local/nagios/etc/objects/commands.cfg

>Next, we will create a service template for the passive checks. Enter the following lines at the bottom
>of the services section:
# Define a passive check template
define service{
use generic-service
name passive_service
active_checks_enabled 0
passive_checks_enabled 1 # We want only passive checking
flap_detection_enabled 0
register 0 # This is a template, not a real service
is_volatile 0
check_period 24x7
max_check_attempts 1
normal_check_interval 5
retry_check_interval 1
check_freshness 0
check_command check_dummy!0
notification_interval 120
notification_period 24x7
notification_options w,u,c,r
stalking_options w,c,u
}

done in /usr/local/nagios/etc/objects/switch.cfg

>After, we can create actual services to match our service checks being passed by NSCA. Keep in mind that the
>service_description must match the svc_description received in the nsca packet, in our above example using >send_nsca, the svc-description was “TestMessage”. I will continue building a service check using that example:

define service{
use passive_service
service_description TestMessage
host_name localhost
}

done in /usr/local/nagios/etc/objects/switch.cfg

>Restart the Nagios daemon so that it loads the updates in your config file. If you have installed Nagios as a service >you
>can use:
>service nagios restart

following the line....

}


# PASSIVE CHECK SERVICE FROM NSCA

define service{
use passive_service
service_description TestMessage
host_name localhost
}

In the official documentation i didn't find nothing about "use generic service", maybe it is the incorrect config of this attribute the problem?

Can someone help me?

thanx in advance

if you look in templates.cfg you will find a template called generic-service which is one of the default objects in the nagios example configs... so just call the template something else... passive-generic-service or nsca-generic-service.
