Using IBM Rational Performance Tester: Monitoring applications, part 2nd

For real-time monitoring

Introduction: Learn why application monitoring is important in performance testing and how to use IBM Rational performance Tester for application monitoring. This article is part 2nd of a three-part series that describes how to use IBM Rational performance Tester to examine application bottlenecks in the development and testing phases, thereby reducing product phase problems. Other parts of this series describe how to configure Ibm®websphere®application server or BEA WebLogic application server for monitoring applications, analyze test results, and import from ibm®tivoli® products Data.

Real-time application monitoring is able to proactively identify application bottlenecks through ibm®rational®performance Tester during development and testing. This approach is useful because it can identify problems before the application is deployed to the product environment, which can reduce the severity of problems that occur after the application is released. In addition, you can use real-time application monitoring to verify the performance of the application that the development group has modified.

Data collection Architecture

Real-time application monitoring in the Rational performance Tester is done using the data-gathering underlying architecture (information collection INFRASTRUCTURE,DCI). The DCI's task is to deliver the application Response measurement (ARM) standard event to the user, which is reported to the Ibm®tivoli®arm engine by the arm-instrumented application (see Figure 1).
