Recording LoadRunner Replay traffic with Fiddler

[Aftab]

Hi,

I am trying to record the replay of LoadRunner Vugen script through
Fiddler(v2.3.3) but the fiddler is not able to capture the requests
send during loadrunner script replay to the server. It is web script
developed using HTTP protocol.

Any suggestions regarding how to achieve this.Your quick help is
highly appreciated.

Thanks.

You should ask the whoever made whatever "LoadRunner Vugen" is how to
set the proxy server for their tool, then follow the instructions
here: http://www.fiddler2.com/fiddler/help/hookup.asp

The following should work:

 

In Run Time Settings

~Internet Protocol Section

~Proxy Sub-Section

Select "Use custom proxy" radio button

Select "Use proxy server"

Enter address 127.0.0.1 in both HTTP and HTTPS fields

Enter 8888 in both Port fields

 

Cheers

In a nutshell, how to I "turn on" Fiddler from inside of VUGen?

Here is the background:

Though I seem to be 2 or 3 years behind the rest of the world, I am trying to build an SAP Business Intelligence (BI) script using LoadRunner 12.5 SAP Web. I get about 10000 lines of script into the use case, but then start fighting 403 Forbidden errors.

I have read enough blogs and forums to know that using Fiddler may help me. However, I have never used the tool before.

I can open IE outside of VUGen and activate Fiddler. I can then record my SAP use case and save the result to a .saz file. I can even open the .saz file in LoadRunner and convert the Fiddler script to a LoadRunner script.

But none of this is what I need to do... I need to somehow figure out what is missing in my current huge LoadRunner script so I can get it to run. I am not sure, but it seems like it would be good to run my script in VUGen and record it in Fiddler. I am not sure what I will find there, but at least it is better than just staring at an error message in the LoadRunner Output log.

I configure the Proxy settings to localhost:8888, but nothing is captured by Fiddler.

So, back to my original question: How do I "turn on" Fiddler from inside of LoadRunner VUGen?

Then, once I capture the LoadRunner traffic in Fiddler, how will I know what I am missing? I have correlated everything in my LoadRunner script that I can find.
