We are currently capturing and reporting a character string length of 8,768, however this does not seem to be the full data string. I have a user that needs to see all of the characters of greater than 10k... is the 8,768 length the maximum size data string that can be collected and reported on?
Actually it's not possible to extend such limits in dynatrace. You can post an RFE for this, but I think this will not be possible because of possible overhead. If those requests are saved in logs, maybe log you can find them there but it's not as comfortable and handy.
