AW: AW: Cascading Services/Service hierarchy

[Gerd Müller]

Sorry I am not sure if I understand your question right. But sounds like
you are again mixing up slas with physical services. The availability of
your website/shop/... is different from the availability of the
webserver. You should define both views. 

An example: your webserver still can be active but only displays "shop
is closed". Wouldn't that be bad ;-) ? So the webserver (http) would be
ok but the shop (in this case your sla-service!) would be critical. So
both service definitions are esential.

BTW: for check_cluster have a look at
http://nagios.sourceforge.net/docs/1_0/clusters.html

> Just so I am clear on this. The status is not propogated from a service to the dependant service. For example, we have a web service that is dependant on the network service. If the network service goes down, the web service is logially not accessible. You can tell Nagios not check the Web services at this point because it makes no sense to if the network is down. However, the status of the Web service is unchanged. I would have to explicitely check the Web service to see if it were down or set the status of the Web service directly, using something like send_nsca.
