LoadRunner Vuser Technology
On each Windows host, you install a
Remote Command Launcher
and an
Agent
.
The Remote Command Launcher
enables the Controller to start applications on
the host machine.
The Agent enables the Controller and the host to communicate with each other.
When you run a scenario, the Controller instructs the
Remote Command Launcher
to launch the LoadRunner
Agent
. The Agent receives instructions from the
Controller to initialize, run, pause, and abort Vusers. At the same time, the Agent
also relays data on the status of the Vusers back to the Controller.
