Evaluating Chariot This application note will walk you through the process of getting started with Chariot. It covers installation, registration and setting up some simple tests, in this case, to test Exchange performance. Installing Chariot and Performance Endpoints When you double-click on setup.exe, Chariot begins to install itself on your computer. The Select Destination Directory dialog lets you decide where to install the Chariot Console. The default directory is \NetIQ\Chariot, on your boot drive. Once you've selected a directory location, Chariot does the rest. Along with the Chariot files, the installation program creates a Chariot folder, accessible from your Windows Start menu. Inside that folder are three icons: Chariot Console, Chariot Help, and Readme. Start Chariot by selecting the Chariot Console icon. To run tests with Chariot, you also need NetIQ's Performance Endpoints software installed on any computer you plan to include in testing. Endpoints are provided free of charge at Users on your network can download the endpoint appropriate for their operating system, or you can use Microsoft's SMS or Tivoli Software Distribution to distribute them throughout your network. NetIQ provides free documentation on installing endpoints on the more than 20 different operating systems supported. Registering Chariot Before you can begin using the evaluation copy of Chariot, you must register it. Here's a step-by-step guide to registering an evaluation copy of Chariot. But you can always press the Help button in any registration dialog to see context-sensitive help about registration. When you start Chariot for the first time, you see the Registration Card Entry dialog. Click the Evaluate Chariot radio button to register an evaluation copy, and press Next to proceed. The Authorization Key Request dialog asks if you need an authorization key. If you've already received a temporary authorization key, click to uncheck the box labeled Get an authorization key and press Next. If you don't have a temporary authorization key, press the Next button. The Internet Access dialog asks if your computer is connected to the Internet. If you respond by pressing the Next button, Chariot opens your default Web browser and takes you to the Request a Product Trial page on the NetIQ web site. An online form appears, with your contact information filled in. Correct the information, if necessary, before pressing the Submit Request button. A NetIQ representation will contact you soon to provide you with a temporary authorization key. Once you have received your temporary authorization key, enter the key in the Registration dialog and press Next. The Registration Summary dialog shows you the number of pairs you are authorized to use in testing with Chariot and the day and time your evaluation license will expire. When you press the Finish button, you may begin using Chariot for testing. The evaluation copy runs as a fully-functioning version of Chariot, but its license limits the number of days it will run. Your evaluation expires at midnight on the last day. Running a Test with Chariot This first test assumes you already have a TCP/IP stack installed and set up correctly on your computer. Here's what you do next: 1. Start Chariot by clicking on Chariot Console in the Chariot folder of your Windows Start menu. 2. In the Chariot Main window, press the New button to open the Chariot Test window. The Test window lets you add pairs of endpoints to a test. 3. Click on the Add Pair icon on the toolbar: . The Add an Endpoint Pair dialog is shown. 4. Enter the following information: 7 The IP network addresses of two computers you plan to test in your network. Remember that these computers must have Performance Endpoint software installed. 7 The network protocol to use in tests. Chariot's default protocol is TCP. 5. Press Select Script and double-click on the script you want to use in your test. For example, the Exchange 2000 scripts can be found in the Business\MicrosoftExchange subdirectory. 6. Press OK to close the Add an Endpoint Pair dialog. You have set up a test to run between one pair of endpoint computers. 7. Run the test by clicking the Run icon on the toolbar: . 8. After the test completes, use the tabs in the Chariot Test window to view your results. Getting Started by Testing with Exchange 2000 Scripts To configure a Chariot test, you create pairs of endpoint computers, as described above. Any computer you use in Chariot tests must have Performance Endpoint software installed. If you're planning to test with Chariot's Exchange 2000 scripts, it's a good idea to install an endpoint on your Exchange server to get the most accurate data about user response times. For each script, set up a Chariot test so that Endpoint 1 represents a client computer, and Endpoint 2 represents an Exchange server. When you press the Select Script button in the Add an Endpoint Pair dialog, you see several subdirectories of Chariot test scripts, which emulate the specific data flows from popular applications, and have the file extension .scr. Three scripts that emulate Outlook and Exchange 2000 traffic on your network are included with Chariot. E-mail Communications Scripts The Exchange 2000 scripts represent three basic activities your users perform in Microsoft Outlook: reading e-mail messages, receiving e-mail messages, and sending e-mail messages. 7 In the exchread.scr script, a client computer contacts the Exchange server and requests a full list of unread e-mail messages. Endpoint 2, acting as the server, sends the unread messages to the client. 7 The exchrcv.scr script emulates a client computer receiving notifications that new e-mail messages exist on the server. Endpoint 1, representing the client, requests the list of unread mail message headers, and Endpoint 2, as the Exchange server, sends the list of unread headers to the client. 7 In the exchsend.scr script, the client computer sends e-mail messages to the Exchange server and receives acknowledgments from the server. You can customize the network traffic generated because the Exchange scripts exchread.scr and exchsend.scr contain a variable, exchange_mail_size, which determines the number of Bytes in each e-mail message. The default size is 1,488 Bytes, which represents 700 Bytes of Exchange e-mail control information (the minimum size of any Exchange e-mail message) and 788 Bytes of text. It's easy to edit this variable; just take the following steps: 1. In the Add an Endpoint Pair dialog, press the Edit This Script button. 2. In the lower half of the Script Editor window, find the exchange_mail_size variable, highlight it, and double-click. 3. In the Current Value field, enter a new value to represent the size, in Bytes, of an e-mail message. To determine the size of a typical message, you can start by assuming that a line of text is about 40 Bytes. What Next: More Complex Chariot Tests This application note was meant to get you started on how to conduct simple Chariot tests. For information on scaling your test to simulate the activities of multiple users of a particular application, see the white paper titled "Loading a Network with Multiple Users" included on the Chariot evaluation CD-ROM and available on the NetIQ Web site. Additionally we have dozens of other scripts available on the Chariot evaluation CD. If you are interested in testing the network performance of a custom application (or any application for which a ready-made script is not available), you may be interested in Application Scanner. Application Scanner is a utility that automatically creates scripts for use with Chariot. In addition to the simple test outlined in this document, Chariot can also do very complex tests of such networking technologies as Voice over IP, Quality of Service, and IP Multicast. For more information about using Chariot's advanced features, please refer to the Chariot User Guide, which is accessible via the Chariot online Help utility.
