lr_debug_message function in loadrunner with examples

We can use this function in two ways with run time settings in loadrunner and with lr_set_debug_message.
Example 1: Set extended log in run time settings(F4)->Log->Extended Log->Data Returned by Server.

Now I have recorded Facebook.com and used lr_debug_message.

If the extended log is enabled it will print the message "I Love Facebook" else it will ignore the message. It will not print any message if the extended log is not enabled.

lr_debug_message(LR_MSG_CLASS_EXTENDED_LOG, "I Love Facebook");

web_url("www.facebook.com",
"URL=http://www.facebook.com/",
"Resource=0",
"RecContentType=text/html",
"Referer=",

Different Ways to do Correlation in Loadrunner You Must Know

1. Generation LogOne of the common options in loadrunner is generation log. You will take the left and right boundary and search in the generation log and use CTRL+F and find the request name and place the web_reg_save_param before that request.
2. Replay LogSometime you do not find correlation value in generation log than the alternative way is go to run time settings and click on Log->Extended Log-> "Data Returned by Server" option and replay the script. Once you replay the script you will use CTRL+F and find the left and right boundaries. Sometimes replay log may fail or it will take a long time if you select “data returned by server” as it is printing all the response to the replay log then the alternate method to use is  lr_set_debug_message as shown in this link.
3. RedirectionIf you are not able to find the value in generation log and replay log then there might be 301 or 302 redirection.  Find out the pages that have 301 or 302 redirection. Once you find the page…
