it's all about the Performance Testing
Welcome to LoadRunner Analysis, HP’s tool for gathering and presenting load test data. When you execute a load test scenario, Vusers generate result data as they perform their transactions. The Analysis tool provides graphs and reports enabling you to view and understand the data.
Each graph has a legend which describes the metrics in the graph. You can also filter your data and sort it by a specific field.
To monitor the scenario performance during test execution, use the online monitoring tools described in the Controller section of this guide. To view a summary of the results after test execution, use one or more of the following tools:
This section describes basic concepts that will enhance your understanding of how to work with Analysis.
When you run a load test scenario, data is stored in a result file with an .lrr extension. Analysis is the utility that processes the gathered result information and generates graphs and reports.
When you work with the Analysis utility, you work within a session. An Analysis session contains at least one set of scenario results (.lrr file). Analysis stores the display information and layout settings for the active graphs in a file with an .lra extension.
You can open Analysis as an independent application or directly from the Controller. To open Analysis as an independent application, choose one of the following:
To open Analysis directly from the Controller, click the Analysis button on the toolbar or select Results > Analyze Result. This option is only available after running a load test scenario. Analysis takes the latest result file from the current scenario, and opens a new session using these results. You can also instruct the Controller to automatically open Analysis after it completes scenario execution by selecting Results > Auto Load Analysis.
When you run a load test scenario, by default all Vuser information is stored locally on each Vuser host. After scenario execution, the results from all of the hosts are automatically collated or consolidated in the results folder.
You disable automatic collation by choosing Results > Auto Collate Results from the Controller window, and clearing the check mark adjacent to the option. To manually collate results, choose Results > Collate Results. If your results have not been collated, Analysis will automatically collate the results before generating the analysis data.
If the behavior of Analysis is unpredictable and unexpected messages appear, this might be a result of UAC Virtualization being been enabled for Analysis. You can disable UAC Virtualization on the Analysis.exe process in the Windows Task Manager.
Analysis graphs are divided into the following categories:
