Information written to tables for a database event monitor

Information written by an database event monitor when the WRITE TO TABLE option is specified.

When you choose WRITE TO TABLE as the ouput type for the database event monitor, by default, three tables are produced, each containing monitor elements from one or more logical data groups:

Table 1. Tables produced by DATABASE write-to-table event monitors. The table name is derived by concatenating the name of the logical data group used to populate the table with the name given to the event monitor (as represented by `evmon-name` in the table names shown in the following table) in the CREATE EVENT MONITOR statement.
Default table name	Logical data groups reported
DB_`evmon-name`	Refer to event_db in Event monitor logical data groups and monitor elements
DBMEMUSE_`evmon-name`	Refer to event_dbmemuse in Event monitor logical data groups and monitor elements
CONTROL_`evmon-name`	The CONTROL logical group consists of selected elements from one or more of the event_dbheader, event_start and event_overflow logical data groups.

To restrict the output of the event monitor to specific tables, specify the names of the logical groups for which you want tables produced in the CREATE EVENT MONITOR or ALTER EVENT MONITOR statements. Refer to the reference topics for those statements for details.

For information about the output returned when the event monitor writes to a file or named pipe, see Event monitor self-describing data stream.

Control table

Table 2. Information returned for a database event monitor: Default table name: CONTROL_`evmon-name`
Column name	Data type	Description
EVENT_MONITOR_NAME	VARCHAR(128)	event_monitor_name - Event monitor name
MESSAGE	VARCHAR(128)	message - Control table message
MESSAGE_TIME	TIMESTAMP	message_time - Timestamp control table message
