Enable Child/Parent relations between hosts monitored on different sites
Currently the Parent of a host always needs to be monitored on the same site. This causes that we need to add dummy hosts, having the same IP as the really monitored host, to be able to enable the usage of child/parent functionality.
It would be great if it could be enabled that parents could be set with hosts from a different site.

Lars MichelsenThe parent/child mechanic is mainly used by a monitoring core in a single site to distinguish between DOWN and UNREACHABLE states. How would that work between multiple cores?

Robert SanderThis will not be possible as the monitoring cores of the distributed sites would have to talk to each other.

Ralf Spenner MergedWhen using multiple sites in the distributed monitoring it is not possible to define a parent of a host when the parent is located on a different site. When having one site for each location and another site for centralized network components it would be great to offer the opportunity to define a host on the centralized site as parent of hosts on one or more location site.

Robert Sander MergedThere is no communication between the monitoring cores of separate sites.
There is no protocol to do that.
I do not think this is even remotely feasible. -

Andy MergedThis is a side-case of https://features.checkmk.com/suggestions/296865/support-piggyback-data-from-remote-hosts
We want to implement "parent host" to be able to visualise dependencies on hosts. However as we run distributed monitoring we cannot do that as the status host needs to be on the same checkmk site has the main host. That is of course no near possible in a distributed setup in a large environment. For example networking equipment or cventers might needs to be monitored on a different site than a VM.
This makes it impossible for us to use the feature all together
The automatic network scan also seems to be faulty, as it will use the main site when doing traceroute. Even in a small setup your network might vary very differently from your main site and your slave site. Only mentioning it here, its not a feature request, I rather see that as a bug. -

Jan BeckI'd also like to have that feature. We've split our single Checkmk instance into two instances, mainly to avoid perfomance issues from large numbers of network devices that are monitored via snmp and each have dozens or hundreds of checks. We'll have to use dummy hosts for parents and we'll have to change the parent assignements whenever we move hosts between the instances. This feature would make our configuration much simpler and more flexible.

Robert Sander MergedThe parent relationship is configuration for the monitoring core to be able to decide if a host is unreachable or down.
The monitoring cores do not talk to each other (and possibly never will).
So this feature request has a near 0% chance of being implemented. -
