Hello, i am trying to setup service dependecies. My configuration is:
apply Dependency "visitor_realms_home_servers" for (server in
service.vars.home_server) to Service {
parent_host_name = server
parent_service_name = service.vars.visitors_realm + "@" +
service.vars.visitors_realm
disable_checks = true
assign where service.vars.home_realm_check == "0"
}
Dependecies are created correctly but i guess i want to achieve
something that is not currently possible.
Created dependencies look like this:
Object
'radius.fit.cvut.cz!akademie-hotelnictvi...@fit.cvut.cz!visitor_realms_home_serversradius.akademie-hotelnictvi.cz'

This one is fine, because the domain "fit.cvut.cz" has only one host
associated with it. The problem appears when there are more hosts
associated with the domain:

Could i somehow relate these two (or more dependending on number of
hosts)? Could i specify when the dependency should be applied - for
example when both (all) services are down or when only one is down?
I've found
https://monitoring-portal.org/t/multiple-host-dependencies/1683/7 and
https://github.com/Icinga/icinga2/issues/1869
Both these topics seem to me that they are highly related to my problem,
but not exacly what i'm trying to solve.
Could someone please clarify is some conditions (and/or) are possible
with this configuration? In case it is not possible, workaround
suggestions are welcome.
What is the current behavior when evaluating if the dependency is
applied or not with this configuration?
Thanks for help,
Vaclav
