I found user name and user action Metadata Capturing (-;
Hi Henk,
What other metadata are you looking to capture?
Request attributes can be setup in Dynatrace that can pull data from many sources - available options are .NET method parameters, HTTP POST parameters, HTTP request headers, HTTP response headers, Java method parameters, web request URL, and web request URL parameters. These can be seen and configured by going to Settings --> Server-side service monitoring --> Request Attributes in your environment.
Hope this helps,
Hayden
