Recently we have patched our SharePoint 2013 on-premise farm to Configuration database version: 15.0.4763.1000. We found that after patch all site collections' popularity trend report shows zero count after the date of patch. The counts before patch date are correct.

I cannot find any bug report about it. Could you please advise where to check?

UPDATE: I checked the EventStore folder (`C:\Program Files\Microsoft Office Servers\15.0\Data\Office Server\Analytics_{GUID}\EventStore`) contains folders with date before patch. So it means the patch make the EventStore stop update. Also I checked the Usage File Creation at `D:\LOGS\RequestUsage\`. The `ImportProgress.ini` file is up-to-date according to last modified date.
