Data generated by locking event monitors

Locking event monitors produce data about locks and deadlocks in the system. You can choose to have the output from a locking event monitor to regular tables, or to an unformatted event (UE) table. If data is written to a UE table, you must perform post-processing on it to view the data.
Regardless of the output format you choose, locking event data comes from one of four logical groups: If you choose to have the locking event data written to regular tables, data from an additional group (CONTROL) is used to generate meta-data about the event monitor itself.
Note: By default, only deadlock information is generated for locking event monitors. To have other types of locking data generated, you must enable collection of that data explicitly.
