Cookie Persistence configured on VS but no logs

Good day all,

I have default cookie persistence profile configured on my VS (Virtual Server > Load Balancing > Default Persistence Profile: cookie) and I've enabled the system to be able to view in the GUI (#tmsh modify sys db ui.statistics.modulestatistics.localtraffic.persistencerecords value true).  The issue is that I see no logs in tmsh (#tmsh show /ltm persistence persist-records) or in the GUI (Module Statistics > Local Traffic > Persistence Records) and I have active sessions to the VS.  I feel I should see something.  Thoughts?  

As always, I look forward to your input and it is greatly appreciated.  Thank you.  

Sincerely,

Paul C.
