Introduction to Output window in VUGEN

Out Put window in Vugen: The main windows in the output window section of Vugen are :

• Replay Log
• Recording Log
• Generation Log
• Correlation Results
• Run time data

Replay Log:

This log gives the details as the vuser runs. This Log provides the details like the requests that vuser has sent to the server and corresponding responses server has sent back. This helps you to validate your script whether it ran without any errors.It helps you a lot to debug your script if script is failing. If you double-click on a line beginning with the Action name, the cursor jumps to the step within the script that generated. This log is generated when you run your script. It also shows the parameter substitutions, you can pass custom messages into this log. You will really appreciate the importance of this log going forward.

Recording Log:

You can view information about the recording and the script generation by viewing the logs in the bottom window. This log has all the communication messages that happened between the client and the server during recording. You can set the level of detail for this log in the Advanced tab of the Recording options. Deleting this file will not affect script’s replay.

Generation Log:

This log is used to view a summary of the script’s settings used for generating the code.This view shows the recorder version, the recording option values, and other additional information. This log is generated after recording. This log is also helps in correlation (Which is a very important concept in loadrunner which I would be explaining futher)

Correlation results:

This tab displays the differences between recorded and replay snapshots. This is helpful in deciding which values to correlate when you want to perform automatic correlation. Auto correlation is not always advisable, manually correlating yields best results and helps in developing a stable script. Run time data:You can track the script information like iteration, action and line number it’s executing. The Parameters section under this displays the value that is being substituted based on their update modes for all the parameters defined in this script
