I'm trying to better understand the info shown in the Responder States tab of an alert.
I will see things like "No Rule" but it doesn't tell me rule for what. I think it's only showing that status as it relates to the last notification that went out for the alert. So maybe it's no rule for closure, not no rule for new alerts. But I can only guess because that context isn't given, or else I have to sift through the much noisier Activity Log.
So far I've found no documentation to confirm this theory, and would welcome some clarification.
