Windows NT Performance Monitor collects information from Microsoft® SQL Server™ using remote procedure calls (RPC). Any user who has Microsoft Windows NT® permissions to run Performance Monitor can use it to monitor SQL Server.
Note When using Windows NT Performance Monitor, you cannot connect to SQL Server running on Microsoft Windows® 95/98.
As with all performance monitoring tools, expect some performance overhead when monitoring SQL Server with Windows NT Performance Monitor. The actual overhead in any specific instance will depend on the hardware platform, the number of counters, and the selected update interval. However, the integration of Windows NT Performance Monitor with SQL Server is designed to minimize the impact.
