What does LoadRunner controller do?
What does LoadRunner controller do?
Controller. The LoadRunner Controller controls the execution of performance tests. It has a user interface which allows various aspects of the test to be set up, including the number of Vusers, the script to be run by each Vuser and the duration of the test.
What is the difference between controller and load generator?
Controller (Licensed Component) – Test Execution and Management (1 max as per its architecture). Load Generator (Non-Licensed Component) – Virtual User Generation for Load Testing. Analysis – Test Result & Monitoring Samples Analysis and Application Performance Reporting can be also used for comparing the test results.
How do you add multiple generators to a controller?
How to add Multiple LoadGenerators for single script in Controller of load runner
- It is very easy,just follow these steps.
- Step2:Click on drop down list under Load Generators column and click on “All Generators “button to assign load generators to specific group name in the Group Name column.
What is runtime settings in LoadRunner?
Runtime settings define the way in which a VuGen script runs and logs/reports. Runtime settings can be defined in a VuGen script or in the Controller while running the test (Runtime settings in the Controller overrides the one set in the script).
What is ramp up and ramp down in LoadRunner?
Q. 58 What is Ramp-up and Ramp-down? Ans: The user ramp up decides the rate at which virtual users add to the load test whereas ramp down instructs LoadRunner at which rate virtual users exit from the load test.
What is the difference between LoadRunner and Performance Center?
LoadRunner Controller(s) ca be standalone or act as a Controller node as part of a larger performance center architecture. Performance Center replaces your user interface with a web-based console for your activities. Also Performance Center is simply Loadrunner wrapped up in a web front end.
What is rendezvous point in LoadRunner?
In LoadRunner, Rendezvous point is used to force the Vusers to perform the simultaneous task during the test execution. Rendezvous point instructs Vusers to wait during test execution for multiple Vusers to arrive at a certain point, in order that they may simultaneously perform a task.
What is the minimum RAM for LoadRunner?

|---|---|
| Memory (RAM) | Minimum: 2GB Recommended: 4GB |
| Free Hard Disk Space | Minimum: 40 GB |
| Screen Resolution | Minimum: 1024 x 768 |
What is ramp up time in LoadRunner?
Ans: The user ramp up decides the rate at which virtual users add to the load test whereas ramp down instructs LoadRunner at which rate virtual users exit from the load test. Example: Ramp-up rate – 5 Vusers per 10 seconds.
What is ramp up period?
A “ramp-up” period happens in business when the demand for a product or service is expected to surge. A ramp-up period typically requires a large amount of preparation, from product manufacturing to communications to marketing.
What do you need to know about LoadRunner controller?
Controller, as the name suggests, is a program to “control” overall load test. It is responsible for helping you run your performance test design using the VUGen scripts you’ve already created. It lets you over-ride run-time settings, enable or disable think time, rendezvous points, adds load generators and controls…
Where do I find the runtime settings in LoadRunner?
LoadRunner store the Runtime settings in a file located in the Vuser script folder and applied to Vusers while running the script using VuGen, the Controller or Performance Center. Runtime settings also help to emulate real-world user behaviour during the test run.
How to configure the LoadRunner agent in Linux?
Configure and run the Linux LoadRunner Agent. Open /dat/br_lnch_server.cfg in a text editor. In the Firewall section, set FireWallServiceActive to 1 and save your changes. Run agent_config from the /bin folder to display the following menu:
Where do I find the pacing setting in LoadRunner?
Come back to LoadRunner pacing setting which you can find under runtime settings. As mentioned, ‘Pacing’ is the second tab of the runtime settings window under General category which controls the rate of iterations during the load test. LoadRunner provides three ways to insert pacing in the script.
