My client is using it using Dynatrace User Experience Monitoring (UEM) for capturing performance metrics from the user's perspective. More information on Dynatrace can be found here -> http://www.dynatrace.com/en/index.html
Steps to Reproduce
Followed the standard steps for setting up Dynatrace UEM with any web application
No error message. But the script tag inserted into the Pega application is stripped out.
can you attach the fiddler trace? Also does this work without webserver? i.e., direct access to prpc. Sometimes, webserver will inject certain js and break the prpc. Just want to make sure that is not the case.
What I mean by that is your topology of the system, e.g., is there a proxy server/load balancer/web server involved before the Websphere application server. These are pretty common in the real enterprise setup. I have to say that I do not have any experience on dynatrace UEM, so really cannot give you detailed guidance. Maybe someone else has done that can shed some lights. But if I were setting up myself, I would try UEM with simplest setup (not realistic but starting from simple case), i.e., direct access app server. Just by glancing your fiddler trace, I am pretty sure, you are going through some sort of web server through https (with plugin to Websphere application server).
Dynatrace eventually will need to be set up in production which will of course have a load balancer. However, I have asked the Dynatrace expert to try in an environment which doesn't have a load balancer to rule out the possibility that it is causing the issue.
