Multi-Host Combined Load generation

Multi-Host Combined Load generation
When LoadRunner puts pressure on the application, the method used is to let a machine simulate many users and send requests or perform operations to the tested users at the same time. In this way, if the number of virtual users simulated by a testing machine is too large, the decline in performance will directly affect the testing effect. To avoid this situation, LoadRunner allows multiple machine running scenarios to balance the load of the test machine. As long as a machine has installed load generator and started the LoadRunner Agent process, it can be centrally scheduled by the Controller to run the scenario. The controller load collects unified test information and execution results.
? » Install load generator. If a test machine is only used for the execution scenario called by the Controller, you only need to install load generator. You can select the load generator option on the homepage of LoadRunner installation. Note that after the load generator service is started, an agent icon is displayed on the taskbar in the lower-right corner of the screen;

» Before creating a load generator controller in the Controller for multi-host combined load generation, load the ready-to-use load generator and click generators in the scenario Setting dialog box. The load generators dialog box is displayed;

» In the load generator dialog box, you can view all loaded load generator information. ?

Name: name of the machine where the load generator is located. If it is localhost, it indicates that the generator is on the local machine;

Status: identifies the current status of generator ,?

Platfrom: displays the platform name of the system;

Click aadd to add a new load generator. After adding a load generator, you must test whether the controller can correctly connect to the generator and click Connect, loadRunner's controller will try to connect to the selected load generator. If the connection is successful, read will be displayed in the Status field. If the connection fails, failed will be displayed.

» Use different load generators to jointly generate loads in scenarios

After creating loadgenerator, you can choose to use it in the load groups list of the controller,
When multiple load generator running scenarios are used, different virtual user groups can run on different machines, breaking down the pressure of the controller itself, and better reflecting the real operating environment of the system;
