Can you let me know size & type of the Dynatrace.identifyUser field. Can the whole field be displayed on the User sessions page?
Current client has stated that a value they are putting into this field is getting truncated, but have not yet provided the datatype & size of the element they are capturing.
I tested it and it does not get truncated (only text ellipsis at the end if too long for the screen). Also shows up correctly in filter. The hover tooltip shows the full length username. See screenshot below:
I testet this with Dynatrace SaaS - which at the time was at Sprint 139. Does this occur for you on Dynatrace Manages as you are asking for my Version?
I just validated it on a Dynatrace Managed installation (Sprint 136) and there I also see full length of user tags > 60 characters.
