sys.dm_db_mirroring_auto_page_repair (Transact-SQL)

Returns a row for every automatic page-repair attempt on any mirrored database on the server instance. This view contains rows for the latest automatic page-repair attempts on a given mirrored database, with a maximum of 100 rows per database. As soon as a database reaches the maximum, the row for its next automatic page-repair attempt replaces one of the existing entries. The following table defines the meaning of the various columns.
