Hi Andreas,

i know that if i don't define an command in the f.e. service definition that
nagios will use the on in the template.

I started to generate a service definition und two templates one for the
master and one for the slave.

Here are an exaple:

define service{
        use
freschness-20min,GL-Tcoder-Active-Service,pnp
        host_name                       gl-tcoder-sw
        servicegroups                   interface
        service_description             Port1
         check_command                    check_mb_snmp_int!1
        }

Master Template, template pnp and freschness is only to set the
checkfreschness and extinfo on the Master server and on the slave they are
empty

define service{
    register                        0
    name                            GL-Tcoder-Active-Service
    active_checks_enabled           0
    check_period                    24x7
    max_check_attempts              3
    normal_check_interval           5
    retry_check_interval            1
    passive_checks_enabled          1
    obsess_over_service             0
    check_freshness                 0
    event_handler_enabled           0
    notifications_enabled           1
    notification_interval           120
    notification_period             24x7
    notification_options            w,u,c,r,f
    contact_groups                  rss,streaming
}

Slave Template

define service{
    register                        0
    name                            GL-Tcoder-Active-Service
    active_checks_enabled           1
    check_period                    24x7
    max_check_attempts              3
    normal_check_interval           5
    retry_check_interval            1
    passive_checks_enabled          0
    obsess_over_service             1
    check_freshness                 0
    event_handler_enabled           0
    notifications_enabled           0
    notification_interval           120
    notification_period             24x7
    notification_options            w,u,c,r,f
    contact_groups                  rss,streaming,bereitschaft
}


you can see that i am only change the definition from active on the slave to
passiv an the master. With the problme on the master if he is trying to
check freschness that he will try the interface check.

If i want to use the check_dummy an the main server i have to move thec
checkcommand in the templet definition. So that i can define on the slave
template the snmpcheck and on the master template the check_dummy.

wenn i will do it that way i have to generate for every interface i want to
check one template. I think in my case it would be nearly 150 templates for
diffrent plugins and args.

my intention is now to write it taht way but in the master template i will
define an checkcommand with check_dummy so that i don't need the additional
templates.

in addition i want to try to have a minimum of definition that are uniq on
the slaves. In my setup it only the templates ans host- and service- groups
the rest i kan use 1to1 from the Master and it will be easier to sync the
config.

In the meentime i will try to go throuh the source code and look if i'm
able  to  make a patch for this behavior but my C is a lot worther then my
english.

I hope this helps because i don't know ta way o describe it better.
