Feedback subsystem overview
The Feedback listener captures data and writes it to the Feedback database schema for subsequent reporting, a capability which can be used to persist data in ways that specifically meet our requirements.
Logging occurs when a rule or logging bean is present in JSP or
servlet a user visits. In either case, during execution an event
containing data to be logged is generated and dispatched by the log
manager to a set of listeners.Personalization supplies two such
listeners. The first is the Feedback listener, which captures data
and writes it to the Feedback database schema for subsequent reporting.
The second is the LikeMinds listener (LMListener), which captures
data for subsequent use by the LikeMinds recommendation engine. Web
site developers can optionally extend the provided listeners or create
additional custom listeners to persist data in ways that specifically
meet their needs.
- Logging events are generated by Personalization rules or logging beans.
- The Feedback subsystem's multi-threaded implementation prevents HTTP clients from waiting.
- The Log Manager maintains internal queue of events.
- Event is dropped on queue then control returned to web client.
- Events are dispatched from the queue to all registered listeners.
- Listeners in turn persist and process the data contained in the logging event.
