I thought I understood how notifications work in Opsview (3.5.2 on Red

think
they do.
We had an issue where one of our users wasn't getting notified of host
outages for a hostgroup that he was authorized for. I looked at the
Nagios config and there were no contactgroups listed in his contact
record. After a couple of days of fiddling with the host and service
groups, I found that the contact configuration will only contain hosts
where he is *also* the contact for one or more services on those
hosts.
Also that he will only be notified about services where he is in both
the hostgroup and servicegroup for those services.
For example, if I have the following
* hosta - hostgroup aa
o mail - servicegroup mail
o snmp - servicegroup monitoring
o nrpe - servicegroup monitoring
* hostb - hostgroup bb
o mail - servicegroup mail
o snmp - servicegroup monitoring
o nrpe - servicegroup monitoring
If I check hostgroup aa and nothing else, my user will receive no
notifications.
If I check hostgroup aa and servicegroup monitoring, he will receive
notifications for hosta and the snmp and nrpe services only on hosta
I really think the host groups and service groups need to be uncoupled
in the notifications. If I am a contact for hostgroup bb, then I
should
get notified of events for for hostb, whether or not I am a member of
any servicesgroups on that host.
Documentation on object selection is here:

There's a note re: host selection only if a service is in that host.
As the note says, the reason we only choose hosts only where a service
exists is because of manageability. If you select "All host groups"
but choose only the "Mail" service group, then hosts that do not have
any mail services will not be selected. We think this is right because
you do not want to give access to that other non-mail hosts
unnecessarily.
I've updated the best practices document to include a "duplicate of
host check as a service check":
* http://docs.opsview.org/doku.php?id=opsview-community:bestpractices
Along the same lines, if I am a
contact for servicegroup monitoring, I expect notifications for all
services in that group, not just ones where I am also a contact for
the
hostgroup that host happens to be in.
As explained above, you can achieve this by saying "all host groups"
with the selected service groups.
Does that explain it? Does that cover your requirements?
