You can monitor details about the current activity and the task history of each replication agent in Replication Monitor. As an agent operates, it writes details of its activity and messages to the history table in the Distributor.
You can display errors if the agent has encountered any during an agent session. The error details are displayed in the Error Detail dialog box. You can also display error information while in the Session Details dialog box, or right-click an agent and then click Error Details.
