ClusterGroup Confusion

[nickanderson1982]

Maybe I'm not understanding the logic. I create a cfg file with hosts and services. Do I not need to include hosts and addresses? Is it just a cfg file and then check services statement?

I'm just used to creating a host file and adding services to it. This is a concept I haven't setup before. Can you please clarify for me.

you wuld create a host/service like this

Code: Select all

define host {
    host_name          CLUSTERHOST
    use                generic-host
    address            CLUSTERHOST
    register           1
}

define service {
    host_name                CLUSTERHOST
    service_description      SERVICENAME
    use                      genericnet-service
    check_command   check_service_cluster!"DNS Cluster"!1!1!$SERVICESTATEID:APIA-A:DNS Service$,$SERVICESTATEID:APIA-B:DNS Service$,$SERVICESTATEID:APIA-B:DNS Service$
    register                 1
}

Obviously replacing APIA-A and APIA-B and "DNS Service" in the check_command to match the actual host and service name of the hosts and services in the cluster

I created the cfg file with my settings but I am receiving a critical message.


define host {
host_name APIA-Servers
use generic-host
address APIA-Servers

contact_groups admins

}

define service {

use generic-service
check_command check_service_cluster!"Name Event Processor [Prod]"!1!1!$SERVICESTATEID:APIA-1:"Name Event Processor [Prod]"$,$SERVICESTATEID:APIA-2:"Name Event Processor [Prod]"$

You should not have " in here inside of the macros

Code: Select all

define service {


check_command check_service_cluster!"Name Event Processor [Prod]"!1!1!$SERVICESTATEID:APIA-1:"Name Event Processor [Prod]"$,$SERVICESTATEID:APIA-2:"Name Event Processor [Prod]"$


}

Replace with

Code: Select all

check_command check_service_cluster!"Name Event Processor [Prod]"!1!1!$SERVICESTATEID:APIA-1:Name Event Processor [Prod]$,$SERVICESTATEID:APIA-2:Name Event Processor [Prod]$

[scottwilkerson]

Also, what is the current state of host / service?
APIA-1 / Name Event Processor [Prod]

is APIA-1 the actual full hostname?

Scott, thank you for your assistance. That was the issue. I appreciate you walking me through this concept from beginning to end. This ticket is completed.
