AND / OR service dependencies in Icinga / Nagios

Question

I've been setting up an Icinga instance using service dependencies as so:

define servicedependency{
    dependent_host_name                             ahost
    dependent_service_description                   Battery Time
    host_name                                       powerware1
    service_description                             UPS Input 1 Voltage
    notification_failure_criteria   o
}
define servicedependency{
    dependent_host_name                             ahost
    dependent_service_description                   Battery Time
    host_name                                       powerware1
    service_description                             UPS Input 2 Voltage
    notification_failure_criteria   o
}

These work, but suppress the alerts for "Battery Time" if either of the inputs is working. How can I adjust this so it suppresses only if both of the inputs are working?

Answer 1

You can set up a meta-service that uses check_multi (or check_cluster) to check both of the voltage check services, and use that for the service dependency.
