10.5.2 Recording Rules Page: How It Works
You can think of the Recording Rules page as a workspace for creating recording rules
(rules that determine how the analyzer records traces). Recording rules are combinations
of events and actions.
An event and the action or actions associated with it form a rule state. One or more states
are encapsulated in a sequence.
Note: There can be from one to 512 states within a sequence. You can associate
one or more events with each state, and you assign each event a different
action or the same action.
A sequence that has only one state is called a single-state sequence. The analyzer
continuously watches for each event in the sequence and executes the corresponding
action if the event is detected.
A sequence that has multiple states is a multi-state sequence. The states are arranged
in a hierarchy, with a top state and successively lower states. Only one state in a
multi-state sequence is active at a time. The analyzer does not go to a successive state
unless it is directed to do so by the previous state.
Sequences are described in detail in “Using Sequences” later in this chapter.
Briefly, creating a rule involves the following steps:
Step 1 Creating Event buttons in the Available Events area.
Step 2 Drag-and-drop of Event buttons to the appropriate areas (cells) in the
Main Display area.
Step 3 Assigning an action or actions to each Event button.
