Run System Monitor
Applies To: SQL Server 2016
System Monitor uses remote procedure calls (RPCs) to collect information from Microsoft SQL Server. Any user who has Microsoft Windows permissions to run System Monitor can use System Monitor to monitor SQL Server.
As with all performance monitoring tools, expect some performance overhead when you use System Monitor to monitor SQL Server. The actual overhead in any specific instance depends on the hardware platform, the number of counters, and the selected update interval. However, the integration of System Monitor with SQL Server is designed to minimize any reduction in performance.
