If we create a Dependent Service definition relying on a single host, and have services on other hosts relying on that service, and set that host and all of its services in Scheduled Downtime, will XI stop alerting on all dependent services?

e.g.

• webserver.host
  • database.host
    • OracleInstance.service
    • OracleBackups.service
  • Firewall.host
    • PublicURL.service
    • PrivateURL.service

... and we mark "webserver.host" in Scheduled Downtime, will it still alert if 'PrivateURL.service" goes down?

If we create a Dependent Service definition relying on a single host, and have services on other hosts relying on that service...

Service dependencies will work - you can make some services dependent on another service, however you cannot make a service dependent on a host. If you try, you will get an error: Perhaps, you can make the the ping service on the "Firewall.host" dependent on the ping service on the "webserver.host", then make "PrivateURL.service" on the "Firewall.host" dependent on the ping service on the same host. I know it sounds complicated.

Ok, yes, but, the question is, still, if we mark the service at the top in Scheduled Downtime, will it drop alerting for its dependents?

I don't believe so.

The reasoning I have behind this is that dependencies are triggered by the state of the service for which they are being depended upon.

For example: If the service being depended upon is in scheduled downtime, but the the service remains in an OK state, then the dependency does not take affect as it only applies to the defined states, like w,u,c,p.
