The dynamic management view (DMV) sys.dm_exec_requests returns information about each request that is executing within SQL Server.
Instead of using Activity Monitor to view the status of a Rollback, use this T-SQL code.
Activity monitor is based on window panes and is cumbersome to export any information.
Using t-sql allows extra flexibility in reporting.
