What is HTTP/S Load?
HTTP/S Load, provides all the functionality required to perform realistic HTTP and HTTPS web site performance tests. It is designed to be used to create and run Tests which simulate the activity of hundreds to thousands of users. Realistic web site test scenarios are simulated by recording, modeling and replaying HTTP/S web activity as part of a Test. Resource utilization information from web sites under test can be monitored, collected and displayed along with web site response times. This enables you to identify system limtations or faults before launch, or after web services have been modified, in order to help you design reliable web sites to meet your load requirements and optimize their performance.
HTTP/S Load is comprised of the OpenSTA Architecture Package and several software packages, that enable you to develop Tests. The Commander GUI (Graphical User Interface) runs within the OpenSTA Architecture and functions as the focal point for all Test development activity. Use Commander to develop Tests, run Tests and to monitor the web site responses under load then display the results data for analysis after the Test run is complete.
From Commander launch Script Modeler, the HTTP/S recording and modeling package, and create the Scripts that encapsulate the web activity you want to test. Use Commander to create Tests by incorporating Scripts and data collection Profiles you need. Then run the Test against the target web sites.
HTTP/S Load supplies versatile software that enables you to approach your performance testing in a variety of ways according to your role in performance test project. It caters for the needs of different users by supplying the full range of function and flexibility that e-business project managers and system performance testers need. It provides the functionality required to support the tasks you need to conduct, in order to achieve the objectives of your web performance tests.
About This Guide
This guide supplies conceptual and procedural information about HTTP/S Load. It is designed to be used as a guide during Test development and is structured to reflect the core functions of HTTP/S Load and the peformance test development process it supports. It documents the core functionality of the software in chapter sequence according to this process, from Script, Profile and Test creation, through to running a test and results display.
Make use of the Glossary at the end of the manual if you come across unfamiliar terminology. Look out for underlined text which denotes a glossary entry.
HTTP/S Load documentation assumes you have a working knowledge of your operating system and its conventions; including how to use a mouse and the basic functionality of your operating system. Refer to the documentation that came with your computer or your system administrator for help.
