Have you considered using audit trail  

I guess, you are looking for monitoring incomplete flows and other things,

Click the Where-am-I? icons ( or ) on a user form or worklist to view the diagram of the current flow, with a larger arrow marking the current assignment.

This display shows the stack of one or more incomplete flow executions in progress that lead to a specific assignment or other incomplete shape in the flow. It does not show the entire case history, which might involve other flow executions now completed.

You can refer below links, to understand more about audit trail. It isn't a tool, though an OOTB feature provided by Pega.

An audit trail refers to the history of a work item. Open the Audit tab on a user form to access the audit trail, which shows information that includes which operators worked on the work item and when, and what automatic processes were performed by the application.

Hi Puise.patel,

You can customize the audit trail by using the Work-AddHistory activity. If needed, you can use the Tracer to see how it is called and used. Also, see https://pdn.pega.com/sites/pdn.pega.com/files/help_v722/procomhelpmain.htm#basics/portal/casemanager/customize-audit-trail.htm. Let us know in case of any questions. Thank you.

Best regards,

Tigran
