No events are being recorded in Load runner scripting

Here are the most common reasons why no events are showing in the script:

The events counter keeps increasing, while the generated script is empty

This may be because VuGen’s recording mechanism fails to identify HTTP data. To fix it, ensure that your application indeed uses HTTP Web traffic. If the application uses SSL connections, make sure you choose the correct SSL version (SSL 2, SSL 3, TLS) through the Port Mapping dialog, available by clicking the ‘Options…’ button on the Record > Recording Options… dialog:



The Advanced Port Mapping Settings dialog opens when you click ‘Options…’:



The events counter shows less than five events, while the application keeps getting data from the server

In this case, VuGen’s recording mechanism fails to capture any network activity at all. Ensure that your application really does provide some network traffic, ie. it sends and receives data through the IP network. If an antivirus program is running, turn it off during recording. Check the recording log for any clues about the recording failure. Messages such as “connection failure” or “connection not trapped” can be a sign of the wrongly configured Port Mapping settings.

In addition, if you are recording on a Chrome or Firefox browser, make sure that all the instances of the browser are closed prior to the recording.
