In this practice, you use System Monitor to monitor system resources. You add objects and counters to control what is being monitored, and you then view the three views graph, histogram, and report for output. 1. Click Start, click Control Panel, and then click Performance And Maintenance. 2. Click Administrative Tools, and then double-click the Performance shortcut. Windows XP Professional starts the Performance console with the System Monitor selected. 3. What objects and counters are monitored by default

3. What is a baseline, and what is a bottleneck
4. Why do you need to determine a baseline when you monitor system resources and system performance
Lesson Summary
The Performance console contains the System Monitor snap-in and the Performance Logs And Alerts snap-in. The System Monitor snap-in allows you to monitor the performance of your computer or other computers on the network.

Monitoring and Optimizing System Performance
The System Monitor snap-in provides performance objects that consist of counters for collecting data. You can add any of hundreds of counters, each of which measures a particular aspect of system performance. The Performance Logs And Alerts snap-in records performance data and system alerts on your local computer or from remote computers. A baseline is a measurement derived from collecting data over an extended period of time that represents resource usage under normal conditions. A bottleneck is any component that slows down the entire system s performance.
Case Scenario Exercise
In this exercise, you will read a scenario about using System Monitor to measure system performance, and then answer the question that follows. If you have difficulty completing this work, review the material in this chapter before beginning the next chapter. You can find answers to these questions in the Questions and Answers section at the end of this chapter.
Scenario
You are an administrator working for a company named Fabrikam, Inc., a regional public relations firm with its headquarters in Dallas, Texas, and several branch locations throughout the country. You are working with Pat, a user in the company s accounting department (which is located in the main office). Pat recently noticed that her computer s performance has decreased, and it is functioning at unacceptably slow levels when running resource-intensive applications. The computer is configured as follows:
