So have changed from IP’s to host names in order to start grouping devices. One of the main reasons was for alerts as I only wanted alerts from certain devices. So I created the groups and seem to work fine as when choosing a group only those devices appear. In the Alert rules I specify the groups I want the alert rule to apply to, but from some reason I’m now not getting anything (worked fine before I specified the groups).
Is there something additional that needs to get done?
