Set service only on active host

Icinga 2
3

I use a “virtual” Icinga host object with the HA IP.
This has the 116_cluster_nodes variable set and the same service name as on the HA nodes with the following DSL code as check.

object CheckCommand "116-cmd-only-one" {
    import "plugin-check-command"
    command = [ "/usr/lib64/nagios/plugins/dummy" ]
    timeout = 10s
    arguments += {
        "--message" = {
            description = "Message"
            required = true
            value = {{
                var output_status = ""
                var up_count = 0
                var down_count = 0
                var cluster_nodes = macro("$116_cluster_nodes$")
                var only_one_service_name = macro("$116-cluster-only-one-service$")
            
                for (node in cluster_nodes) {
                  if (get_service(node, only_one_service_name).state > 0) {
                    down_count += 1
                  } else {
                    up_count += 1
                  }
                }
            
                if (up_count == 1) {
                  output_status = "OK: "
                } else {
                  output_status = "CRITICAL: "
                }
            
                var output = output_status
            
                for (node in cluster_nodes) {
                  output += node + ": " + only_one_service_name + ": " + get_service(node, only_one_service_name).last_check_result.output + " "
                }
            
                output += " | count_of_alive_" + only_one_service_name +"="+up_count+";1:1;1:1"
                return output
            }}
        }
        "--state" = {
            description = "State"
            value = {{
                var up_count = 0
                var down_count = 0
                var cluster_nodes = macro("$116_cluster_nodes$")
                var only_one_service_name = macro("$116-cluster-only-one-service$")
            
                for (node in cluster_nodes) {
                  if (get_service(node, only_one_service_name).state > 0) {
                    down_count += 1
                  } else {
                    up_count += 1
                  }
                }
            
                if (up_count == 1) {
                  return "ok" //same up as down -> UP
                } else {
                  return "crit" //something is broken
                }
            }}
        }
    }
}
