Check_MK Services Dependencies across hosts
It would be great to have service dependencies across hosts for Check_MK, just like the host parent/child relationships.
In case that the parent service fails all the child services could go to stale and state that the parent service is down instead alerting all the depending Services.
In case of a downtime the parent service could inherit it's downtime on request to all the child services like it can be done with the host downtimes.
As an example:
If a web server is no longer running, the central active HTTP checks on the CMK server do not have to alarm.
