In our company we use two ways:
1. We have dedicated plugin to save chosen data to json scripts which will be prepared to LoadRunner schema.
2. Second way is use Elasticsearch to collect and corelate interesting data. In the next step we are prepared dedicated script like i wrote in first point.
*You can used data from UEM, Business Transactions and Load tests.
Other thing to consider is using the LoadRunner conversion tool to add unique headers into your script and look at them in the Tagged Web Request dashlet for native viewing from your app servers.
