OVERVIEW

Master ALM Performance Center and the Virtual User Generator (VuGen) application in order to develop, execute, and analyze performance test results. Learn how to develop a performance test plan that can be executed with Performance Center. Topics covered include planning, scheduling, script development and debugging, with heavy emphasis on hands-on labs. Learn how to develop tests that monitor and measure SLAs and find out which reports and graphs are most useful in addressing—and correcting—system performance. This course is divided into two parts, as follows:

Part 1 (2 days) Using Performance Center Concepts

Learn how to create, run and analyze tests in Performance Center.

Part 2 (3 days) LoadRunner Scripting for Performance Center

Learn how to use VuGen for planning and recording of test scripts, enhancing tests, and adding custom code through advanced scripting.
