The Dynamo Data Collection facility provides a flexible way to collect information. Like Logging, Data Collection is based on the Java event model. But Data Collection lets you record data contained in any JavaBean (not just subclasses of LogEvent). Like the Logging system, the Data Collection system includes components that act as sources, events, and listeners. In addition, Data Collection summarizer components perform in-memory summarization. The following topics describe the components of the Dynamo Data Collection system:
Data Collection Sources and Events
Data Listeners
Formatting File Loggers
Database Loggers
Data Collector Queues
Summarizers
