The more important and critical component of Loadrunner is the Controller. Loadrunner uses the Controller to emulate the real time users. Here is where we configure our scenario settings like Scripts need to be executed No of Vusers Load Generators Run-time settings Load test duration etc..
Load Runner uses Controler to create manage & maintain scenarios .It also manages vusers to emulate the real time user.It is also configuers the starting and ending of execution of the scripts no of vusers run time settings Load test duration.
Controller is one of the important part in Load Testing.It actually load test the Script performance under critical Time when there is maximum number of users.
Controller is like an administrator in the load runner.It manages drives executes and analyse the script and also it emulate Vusers as the real time users.
Controller is a one of the Component in Loadrunner. It uses to design the multi user scenarios and run the scenarios against the load behaviours. In the controller you can design the Benchmark test Load test Stress test Spike test Endurance test.
