Analytics after reinstall

I had some line crossing and other camera rules setup on a server working fine. I had to do some maintenance on the server which involved reinstalling the os and server software. I had done a database backup prior to all this and did a restore afterwards but the analytics events aren’t working anymore. I tried deleting the cameras and re-adding them with a different ip address but that isn’t correcting the issue. Any ideas on how to get the analytics back without doing a completely fresh reinstall? Is there a file that is holding all the analytic information tieing it to the previous install?
