Hello all,

I have various hosts monitored by NRPE.
Then I defined a service checking NRPE availability named NRPE_listener

Is there a way, when any other service fails, first to check if NRPE_listener service is OK for this host?
If it is down, I would like to receive only one notification and suspend all other until NRPE_listener recovers.

Unfortunately the * is not applicable

Code: Select all

define servicedependency{
        dependent_host_name             testpc
        dependent_service_description   *
        host_name                       testpc
        service_description             NRPE_Listener
        execution_failure_criteria      n
        notification_failure_criteria   w,u,c
}

Error: Service dependency definition for service 'NRPE_Listener' on host 'testpc' is circular (it depends on itself)!
Error: Service dependency definition for service 'NRPE_Listener' on host 'testpc' is circular (it depends on itself)!

Can this be done somehow?
I don't want to create numerous definitions and update it for each new host/service

Perhaps you could instead define the 'check NRPE listener' service as parent service, instead of going the service dependency route. I believe that by defining a parent service you avoid the circular problem you mentioned.

Parents --

This directive is used to define a comma-delimited list of short names of the "parent" services for this particular service. Parent services are typically other services that need to be available in order for a check of this service to occur. For example, if a service checks the status of a disk using SSH, the disk check service would have the SSH service as a parent. If the service has no parent services, simply omit the "parents" directive. More complex service dependencies may be specified with service dependency objects.

Yes, this is what I was looking for.

It was introduced in v4, so I have to upgrade also

Thank you
