The easiest method is to trigger a process instanance snapshots https://docs.dynatrace.com/docs/shortlink/host-monitoring#snapshots , but this is available on for Classic environments at the moment.
Other method is to trigger and download a support archive (if you have permissions), where the process snapshost data is also present in a JSON file.
