Viewing the Output Window - LoadRunner

While the scenario runs, the Vusers and load generators send error, notification, warning, debug, and batch messages to the Controller. You can view these messages in the Output window. LoadRunner clears the messages in the Output window at the start of each scenario execution. If you reset a scenario, messages remain in the Output window unless you instruct LoadRunner to delete messages from the Output window upon reset.

To view messages in the Output window:

  1. Choose View > Show Output or click the Show Snapshot button to the right of the Errors listing. The Output window opens, displaying error information.

Viewing Log Information Details

You can view details of each message, Vuser, script, and load generator associated with an error code by clicking the blue link in the respective column. The Output window displays a drilled-down view by Vuser, message, script, or load generator in the Filtered tab. For example, if you drill down on the Vusers column, the Output window displays all the messages with the code you selected, grouped by the Vusers that sent the messages.

Viewing Log Information Details

Note that the message type, the message code, and the column that you selected to drill down on, are displayed above the grid. You can drill down further on the entries displayed in blue. Note that when you drill down on a Vuser, the Vuser log opens. When you drill down on a load generator, the Load Generators dialog box opens, displaying the load generator you selected. When you drill down on a script (or Action or Line Number), VuGen opens, displaying the script you selected.

Note: To limit the number of rows displayed when you drill down, open the wlrun7.ini file in any text editor, and located the following line:

MaxOutputUIRowsToShow=0

Change the 0 (no limit) to the number of rows you want to view. When new messages arrive in the Output window, the Refresh button is enabled. Click Refresh to add the new log information to the Filtered tab view. To move between the various drill down levels, click the Previous view and Next view buttons in the upper-left corner of the Output window.
