You can configure additional settings for individual load generators, using the tabs in the Add New Load Generator or Load Generator Information dialog boxes. The settings that can be configured are: Status, Run-Time File Storage, UNIX Environment, Run-Time Quota, Vuser Limits, Vuser Status, Terminal Services, Firewall, and WAN Emulation. You can also configure the Connection Log Settings while working in Expert mode. You can configure global settings for all load generators participating in the scenario, using the Options dialog box.
To configure load generator settings:
Understanding the Load Generator Information dialog Box
The Load Generator Information dialog box enables you to add a load generator machine to your scenario.
Name: Type the name of the load generator you want to add in the Name box.
Platform: Select the type of platform on which the load generator is running.
Temporary directory: Type a location, on the load generator, where the Controller can store temporary files.
Enable load generator to take part in the scenario: Select to include the load generator in the scenario.
Select the Status tab to display details of the Load Generator Status.
Load Generator Status: Displays the status of the load generator.
Details: Displays error and other run-time information about the selected load generator.
Run-Time File Storage Tab
Select the Run-Time File Storage tab to specify the result directory for the performance data that LoadRunner gathers from each load generator during a scenario.
Scripts and results stored: Select one of the following options:
Note: If the load generator is localhost, then LoadRunner stores the scripts and results on a shared network drive, and the checkboxes and radio buttons for setting the location are all disabled. If you are monitoring over the firewall, the Run-Time File Storage settings are not relevant.
UNIX Environment Tab
Select the UNIX Environment tab to configure the login parameters and shell type for each UNIX load generator.
Shell Settings: Specify the UNIX shell settings for the remote UNIX load generator.
Note: If you are monitoring or running Vusers over the firewall, the UNIX Environment settings are not relevant.
Run-Time Quota Tab
Initializing or stopping a large number of Vusers simultaneously places large stress on a load generator. To reduce stress on a load generator, you can initialize or stop smaller batches of Vusers. Select the Run-Time Quota tab to specify the maximum number of Vuser types that the load generator will initialize or stop simultaneously.
Defaults: Sets the number of Vusers that may be initialized or stopped at one time to 50.
You can set run-time quotas for an entire scenario using the Run-Time Settings tab in the Options dialog box. For information on setting quotas globally for an entire scenario, see Chapter 10, “Configuring a Scenario.”
Vuser Limits Tab
Select the Vuser Limits tab to modify the maximum number of GUI, RTE, and other Vusers that a load generator can run.
Available Types: Select the type(s) of Vusers you want the load generator to run.
Maximum Active: Select the maximum number of Vusers of each type for the load generator to run.
Defaults: Sets GUI-WinRunner to 1, RTE to 1000, and Other Vusers to 5000.
Note: The maximum number of active Vusers that you specify must not exceed the number of Vusers that you are licensed to run. To check your Vuser licensing limitations, in the Mercury LoadRunner window (Start > Programs> Mercury LoadRunner> LoadRunner), click License.
Select the Firewall tab to enable monitoring or running Vusers over a firewall.
Enable firewall: Enables LoadRunner to monitor or run Vusers over a firewall.
Note: If you select the Enable Firewall option, the Temporary directory option for storing temporary files is disabled. Any location in the Temporary directory box is erased.
MI Listener: Type the name of the MI listener the load generator is using.
Note: If the load generator is connected, you cannot change values in the Firewall tab. To disconnect a load generator, select the load generator in the Load Generators dialog box, and click Disconnect. The load generator status changes to Down, and you can change the settings.
The Firewall tab is disabled if the load generator is Localhost.
Vuser Status Tab
Select the Vuser Status tab to view the status of all the Vusers connected to the selected load generator machine. Note that this tab can only be viewed when the load generator machine is connected.
GUI/WinRunner: Displays the number of GUI/WinRunner Vusers that are Pending, Initializing, and Active.
RTE: Displays the number of RTE Vusers that are Pending, Initializing, and Active.
Other Vusers: Displays the number of Vusers other than GUI/WinRunner and RTE Vusers that are Pending, Initializing, and Active.
Totals: Displays the total number of Vusers that are Pending, Initializing, and Active.
