The Windows NT Performance Monitor not only helps administrators fine-tune performance, but it can also warn of approaching problems. Performance Monitor can also help you spot the activity of a virus (by spotting performance degradation) or an attempted break-in (by tracking logon attempts). Performance Monitor can be set to send an alert to one or more administrators when certain events occur. For more information, see Chapter 8, "Monitoring Performance," in Microsoft Windows NT Server Concepts and Planning. For procedural information, see Help.
For a thorough discussion of performance monitoring in Windows NT, see Part 3, "Optimizing Windows NT" in this book.
