SNAPSHOT.TABLES_SNAP_TIMESTAMP

TABLES_SNAP_TIMESTAMP records the start time and end time of data collection, as well as corresponding databases, and table objects for all stored WDR snapshots. Only the initialization user or monitor administrator has the permission to view the table. After the WDR snapshot function is enabled (the parameter enable_wdr_snapshot is set to on), the table is created.
