-Rules apply either before an event gets stored, or immediately after.
-
-Basic actions:
-
-- I want to get notified when [X]
-- I want to group events when [X]
-- I want to scrub data when [X]
-
-Expanded:
-
-- I want to get notified when an event is first seen
-- I want to get notified when an event is marked as a regression
-- I want to get notified when the rate of an event increases by [100%]
-- I want to get notified when an event has been seen more than [100] times
-- I want to get notified when an event matches [conditions]
-- I want to group events when an event matches [conditions]
-
-Rules get broken down into two phases:
-
-- An action
-- A rule condition
-
-A condition itself may actually be any number of things, but that is determined
-by the rule's logic. Each rule condition may be associated with a form.
-
-- [ACTION:I want to get notified when] [RULE:an event is first seen]
-- [ACTION:I want to group events when] [RULE:an event matches [FORM]]
