You should not need to get fancy with the interface down alert since the interfaces on a down node should automatically be placed into an "unreachable" status. What I suspect is that your down interface alert trigger is set to fire immediately. That could cause an interface to be polled as down before the parent node is officially set to a down status. If that happens, the dependency would not yet have been applied and you could get the interface down alert.
I would try setting a threshold of 1 or 2 interface polling intervals on the Trigger tab and see if that eliminates the false interface down alerts.
Question. I have a dependency set up. Core switch as the parent, multiple servers in a group as the child.I have the polling interval set to 120 seconds for the switch and 180 for the servers.
But I still get multiple alerts when the switch goes down.The only thing I can think of is that no matter what I try I never get any alerts under the 'Alerts on Child' tab. I've tried multiple alert types. Should I be seeing something under this tab? Or do you only see something there if the device is actually down? All of the info I've found relating to dependencies seem to indicate that you don't need to do anything with alerts specifically, as long as you have alerts that work? Is that correct?
Up for this topic.
I also want to set dependencies. My lease line router would be the Parent and all equipment after the router are the childs. I have created the dependencie for all my sites but I still get alter on all equipement when they are down including the router... Can someone give me some help, It's the first time I work with solarwind. Maybe I have to create special Alters for dependencies... I juste find information about creating a dependency and nothing else, like all what to do is to add parents, chills and that it...
Thanks for your help.
What does your Logic look like on your alert ie: Trigger Alert When Node STATUS is "Down"or "Not UP""Unreachable"
I know a lot of people that configure their alerts with if "Node is not equal to up" it will fire this can cause some major problems if your dependencies are not correctly configured.
