The new 12.53 Load Runner has very good features, I am amatuer, I see that the Protocol Analyzer feature has been removed from the Record tab of the VuGen, it does not help much i assume


I had a customer mention this very thing today.  Is there any similar replacement feature?

There is no replacement feaure for the protocol analyzer. It was discontinued due to many false or inaccurate analysis. We also tried to consolidate some of the protocols into one in order to make the protocol selection decision less complicated.

in any case there is no way around understanding the communication protocol of the application between the client and the server. Once you know that you can also determine which protocol is the most suitable in LoadRunner.
