Your goal is to monitor all your servers running Windows Server 2003 so that they can be defragmented on a regular schedule, and as efficiently as possible. The disk defragmentation program that you use requires at least 20% free disk space on each volume to defragment properly. What should you do

What is the most likely explanation for the problem
3. The server that you are using to monitor the other servers on your network is overburdened with the task, so you must lighten its load of monitoring. To make the greatest impact for the monitoring computer s performance while maintaining as much monitored data as possible, what should you do
Lesson Summary
The Performance console has two snap-ins configured: System Monitor and Performance Logs And Alerts. The System Monitor is designed for real-time reporting of data to a console interface and can be reported in graph, histogram, or numeric form. The Performance Logs And Alerts snap-in is designed to write data to a file (log) and report counter values that breach a threshold (alert). Logs written by Performance Logs And Alerts can be loaded into System Monitor for analysis and exported to a variety of file types, as follows:
Performance Monitor Binary file (*.blg), with or without circular overwriting Text file (*.txt or *.csv) SQL Database
After you have configured the settings for a log, you can save the Performance Monitor settings (by selecting Save Settings As from the log s context menu) as an HTML file for later use (by selecting New Log Settings From from the Counter Logs context menu).

Lesson 3: Using Task Manager
Task Manager provides information about programs and processes running on your computer. It also displays several common process performance counters.
After this lesson, you will be able to
Configure Task Manager to display performance data Use Task Manager to start and end applications and processes
Estimated lesson time: 15 minutes
Task Manager Overview
Task Manager is an important Windows application that you can use to display information about the computer s current performance levels as well as manage the programs and processes running on the system. You can open Task Manager by right-clicking an open area of the taskbar and then selecting Task Manager from the context menu or by pressing CTRL+ALT+DEL and then clicking the Task Manager button. The Windows Task Manager dialog box contains five tabs by default: Applications, Processes, Performance, Networking, and Users.
Applications Tab
The Applications tab (shown in Figure 12-6) shows the status of the user-level programs currently running on the computer. Services and system applications running in different contexts from the logged-on user are not displayed. For each application listed, the Status column indicates whether the application is running or not responding.

Using Task Manager

By selecting an application from the list and clicking Switch To, you can make the selected application the active window, leaving Task Manager open in the background. You can also select an entry in the list and click End Task to close the application. When you right-click an application in the list and select Go To Process from the context menu, the dialog box switches to the Processes tab and highlights the process associated with the application. This is a helpful feature when you are trying to locate the process for a particular application and the process name is less than intuitive. When you click New Task, a Create New Task dialog box appears in which you can enter or browse for the name of any standard executable file or command. This dialog box is the functional equivalent of the Run dialog box, which is accessible from the Start menu.
