Can you elaborate the requirement for which you want make measure or capturing for?
Do you want to capture the user ID arg or 'TF' field?
Also, take care of non-essential and sensitive fields like Password (as its visible in PurePath). You should avoid capturing them.
Let me know if you have any queries,
Create a measure by right click on highlighted RED one -> create Measure -> Method - argument value ->provide Class/method name(if you right click and create it automatically fills) -> select the argument which provides the number value - > Provide custom measure name -> Apply and save.
Create BT -> add this method in filter and splitting section and restart the JVM/.NET service based on your environment for BT to start collect data. This BT will split the purepath by number which it fetches in this method.
Hope this helps!!
