You emulate user load on the server by instructing multiple Vusers to perform
tasks simultaneously. You can set the level of load by increasing and decreasing
the number of Vusers that perform tasks at the same time.
Before you run a scenario, you set the scenario configuration. This determines how
all the hosts and Vusers behave when you run the scenario.
For each scenario, you create a list of scripts that Vusers run during scenario
execution.
You can run the entire scenario, individual Vusers, or groups of Vusers (Vuser
Groups). While a scenario runs, LoadRunner measures and records the
transactions that you defined in each Vuser script.
