The Job History tab displays all your jobs and tasks historical information.
Every time a job runs, it is recorded in the SQL Server instance. The SQL Enterprise Job Manager displays it as an entry. These events are ordered chronologically with the latest on top, but you can also change this order or use the available filters on the left side to view specific information. For more information, go to Organizing and Filtering your Job History Information.
By default, the Job History tab displays the historical information of your jobs, but you can click the Task History option on the top right corner to access the historical information of your Windows scheduled tasks.
Additionally, you can view the history of your jobs and tasks by going to the Jobs tab, and select Job History or Task History from the drop down list available in the View By section.
