So I found out that the alert suppression is a different function, and that it can be a pain to set up.
All I want is if the parent router(s) is having either packet loss, high latency, or is down, I don't get an alert for every node at the site...
No. Unfortunately dependancy only affects the Node-Down type alerts, and not the others.
i.e. if the parent node is down it puts the dependent notes into 'unknown' rather than 'down' state.
this doesn't affect 'up but not working quite properly' type of alarms. For that you have to code them yourself in the filters, which is nigh on impossible,
for the alerting folks this would be a rule of the form:
'AND this alert is not also triggered (or about to be) on a node that is a parent dependency of the current node'
which might be worth creating an idea for...
Thanks a bunch for the reply
It really seems like with Dependencies, they stopped without finishing. Dependencies are quick and easy to create, you should be able to select alert suppression through building dependencies instead of just up/down notifications.
