So far, Service::GetSeverity() only considered the state of its own host, i.e. the implicit service to its own host dependency, and treated it similar to acknowledgements and downtimes. In contrast, Host::GetSeverity() considered reachability and treated it like a state, i.e. for the severity calculation, the host was either up, down, or unreachable. This commit changes the following things: 1. Make the service severity also consider explicitly configured dependencies by using IsReachable(). 2. Prefer acknowledgements and downtimes over unreachability in the severity calculation so that if an already acknowledged or in-downtime services (i.e. already handled service) becomes unreachable, it shouln't become more severe. 3. To unify host and service severities a bit, hosts now use the same logic that treats reachability more like acknowledgements/downtimes instead of like a state (changing the other way around would the state from the check plugin would not affect the severity for unrachable services anymore).

About
Icinga is a monitoring system which checks the availability of your network resources, notifies users of outages, and generates performance data for reporting.
Scalable and extensible, Icinga can monitor large, complex environments across multiple locations.
Icinga 2 is the monitoring server and requires Icinga Web 2 on top in your Icinga Stack. The configuration can be easily managed with either the Icinga Director, config management tools or plain text within the Icinga DSL.
