4. Users in A. Datum are about to receive their new Windows 8 computers. You must use Performance Monitor to establish a performance monitoring baseline and measure a typical computer's responsiveness under a representative load. This will help to ensure that resources, such as RAM and CPU, are specified correctly for these computers. Objectives Create a performance monitoring baseline. Introduce a load. Measure system performance and analyze results.

Create a performance monitoring baseline.
Introduce a load.
Measure system performance and analyze results.

In this exercise, you create a performance monitoring baseline against which to measure future
performance.
The main tasks for this exercise are as follows:
1. Establish a performance baseline.
2. View the baseline report.

Task 1: Establish a performance baseline
1. On LON-CL1, log on as Adatum\Administrator with the password of Pa$$w0rd, and then open
   Performance Monitor.
2. Create a user-defined Data Collector Set with the following properties:
   o Name: Adatum Baseline
   o Create manually (Advanced)
   o Performance counter
   o Sample interval: 1 second
   o Counters to include:
    = Memory > Pages/sec
    = Network Interface > Packets/sec
    = Physical Disk > % Disk Time
    = Physical Disk > Avg. Disk Queue Length
    = Processor > % Processor Time
    = System > Processor Queue Length
3. Start the data collector set, and then start the following programs:
   o Microsoft Office Word 2010
   o Microsoft Office Excel 2010
   o Microsoft Office PowerPoint 2010
4. Close all Microsoft Office applications, and in Performance Monitor, stop the Adatum Baseline data
   collector set.

Task 2: View the baseline report
1. In Performance Monitor, locate Reports > User Defined > Adatum Baseline. Click the report that
   has a name that begins with LON-CL1.
2. Record the following values:
   o Memory Pages per second
   o Network Interface Packets per second
   o Physical Disk % Disk Time
   o Physical Disk Avg. Disk Queue Length
   o Processor % Processor Time
   o System Processor Queue Length

After this exercise, you should have created a performance monitoring baseline.

2: Introducing Additional Workload

In this exercise, you introduce additional computer workload by running a script that performs various
tasks on the computer.

The main task for this exercise is as follows:
• Create a load on the computer.

Task 1: Create a load on the computer
1. Switch to the LON-CL1 computer and then start the Adatum Baseline.
2. Run the E:\Labfiles\Mod10\Load.vbs script.

After this exercise, you should have generated additional load on the computer.

3: Measuring System Responsiveness Under Load

In this exercise, you compare the results that you collected during performance monitoring with those
collected earlier when you created the baseline.
The main task for this exercise is as follows:
• Identify performance bottlenecks in the computer.

Task 1: Identify performance bottlenecks in the computer
1. Open Resource Monitor.
2. Which components are under strain?
3. After a few minutes, close the two instances of C:\Windows\System32\cmd.exe launched by the
   script.
4. Switch to Performance Monitor, and then stop the Adatum Baseline data collector set.
5. In Performance Monitor, locate Reports > User Defined > Adatum Baseline. Click on the second
   report that has a name that begins with LON-CL1.
6. View the data as a report.
7. Record the component details:
   a. Memory Pages per second
   b. Network Interface Packets per second
   c. Physical Disk % Disk Time
   d. Physical Disk Avg. Disk Queue Length
   e. Processor % Processor Time
   f. System Processor Queue Length
8. In your opinion, which components are the most seriously affected?
9. Close all open windows and programs, and then revert to the Start screen.
