3.Users' InfluenceDisplays average transaction response times relative to the number of Vusers running at anygiven point during the load test. This graph helps you view the general impact of Vuser load on

performance time and is most useful when analyzing a load test which is run with a gradualload.

12.Terminology12.1.LoadRunner Objects

Term Definition

Vuser ScriptsA Vuser script describes the actions that a Vuser performs during the scenario. Each Vuser executes a Vuser scriptduring a scenario run. The Vuser scripts include functions that measure and record the performance of yourapplications components.

Load TestTests a system's ability to handle a heavy workload. A load test simulates multiple transactions or usersinteracting with the computer at the same time and provides reports on response times and system behavior.

Run-Time Settings

Run-Time settings allow you to customize the way a Vuser script is executed. You configure the run-time settingsfrom the Controller or VuGen before running a scenario. You can view information about the Vuser groups andscripts that were run in each scenario, as well as the run-time settings for each script in a scenario, in theScenario Run-Time Settings dialog box.

ScenarioA scenario defines the events that occur during each testing session. For example, a scenario defines and controlsthe number of users to emulate, the actions that they perform, and the machines on which they run theiremulations.

SchedulerThe Schedule Builder allows you to set the time that the scenario will start running, the duration time of thescenario or of the Vuser groups within the scenario, and to gradually run and stop the Vusers within the scenarioor within a Vuser group. It also allows you to set the load behavior of Vusers in a scenario.

SessionWhen you work with the Analysis utility, you work within a session. An Analysis session contains at least one set ofscenario results (lrr file). The Analysis utility processes the scenario result information and generates graphs andreports. The Analysis stores the display information and layout settings for the active graphs in a file with an .lraextension. Each session has a session name, result file name, database name, directory path, and type.

TransactionsA transaction represents an action or a set of actions used to measure the performance of the server. You definetransactions within your Vuser script by enclosing the appropriate sections of the script with start and endtransaction statement.

VusersVusers or virtual users are used by LoadRunner as a replacement for human users. When you run a scenario,Vusers emulate the actions of human users working with your application. A scenario can contain tens, hundreds,or even thousands of Vusers running concurrently on a single workstation.

12.2.Graph InformationTerm Definition

Average Average value of the graph measurement's.

Hits The number of HTTP requests made by Vusers to the Web server.

Maximum Maximum value of the graph measurement's.

Measurement This is the type of resource being monitored

Median Middle value of the graph measurement's.

Minimum Minimum value of the graph measurement's.

Network Delay The time it takes for a packet of data sent across the network to go to the requested node and return.

Network Path The Network Path is the route data travels between the source machine and the destination machine.

Response time The time taken to perform a transaction.

Scale (or granularity)

In order to display all the measurements on a single graph, thus making the graphs easier to read andanalyze, you can change the scale or (granularity) of the x-axis. You can either set measurement scalesmanually, view measurement trends for all measurements in the graph, or let Analysis scale themautomatically. The Legend tab indicates the scale factor for each resource.

Standard Deviation (SD) The square root of the arithmetic mean value of the squares of the deviations from the arithmetic mean.

Throughput Throughput is measured in bytes and represents the amount of data that the Vusers received from theserver.

Vuser LoadWhen you run a scenario, the Vusers generate load or stress on the server. LoadRunner monitors the effectof this load on the performance of your application.
