When the refresh interval is set to less than 10 seconds, the time that is used to run these queries can affect server performance. We recommend that you [download and install the latest version of SSMS](../../ssms/download-sql-server-management-studio-ssms.md). ## Permissions To view actual activity, you must have `VIEW SERVER STATE` permission. To view the Data File I/O section of Activity Monitor, you must have `CREATE DATABASE`, `ALTER ANY DATABASE`, or `VIEW ANY DEFINITION` permission in addition to `VIEW SERVER STATE`. To `KILL` a process, a user must be a member of the `sysadmin` or `processadmin` fixed server roles. ## Open Activity Monitor ### Object Explorer Right-click on the top-level object for a SQL Server connection, and select **Activity Monitor**. ### Toolbar From the Standard toolbar, select the **Activity Monitor** icon.
