Where is the Performance Log and Alerts?

1.     Windows 2000, Windows XP, Windows Server 2000/2003/2008

Performance Logs and Alerts, a service introduced in Windows 2000, improves the logging and alert capabilities that were provided in Windows NT 4.0. Logging is used for detailed analysis and record-keeping purposes. Retaining and analyzing log data collected over a period of several months can be helpful for capacity and upgrade planning.

Windows 2000 provides two types of performance-related logs—counter logs and trace logs, and an alerting function.

2.     Windows Vista/7/8/8.1, Windows Server 2008 R2/2012

Starting from Windows Vista, Windows 7, Windows Server 2008 R2, and Windows Server 2012, Windows Performance Monitor is a Microsoft Management Console (MMC) snap-in that provides tools for analyzing system performance. From a single console, you can monitor application and hardware performance in real time, customize what data you want to collect in logs, define thresholds for alerts and automatic actions, generate reports, and view past performance data in a variety of ways.

Windows Performance Monitor combines the functionality of previous stand-alone tools including Performance Logs and Alerts (PLA), Server Performance Advisor (SPA), and System Monitor. It provides a graphical interface for the customization of Data Collector Sets and Event Trace Sessions.

Windows Performance Monitor performs data collection and logging using Data Collector Sets.
