Data generated by buffer pool event monitors

Buffer pool event monitors produce aggregate metrics about buffer pool activity. You can choose to have the output from a database event monitor to regular tables, files or pipes.

Regardless of the output format you choose, all buffer pool event data comes from the event_bufferpool logical data group. In addition, if you choose to have statement event data written to tables, data from an additional group (CONTROL) is used to generate metadata about the event monitor itself.
