We are unable to upgrade to 3.4 until we get a resolution on this topic, or even a hint of what is causing Matomo 3.4 to track twice the number of visits as Piwik 2.16.5.
Our process was to duplicate our existing server (by imaging it) and run the upgrade by the manual upgrade method. Now we’re running both servers side-by-side and our expectation would be that they would track the same numbers it all cases.
Hi there, thanks for the report. This is something we’d like to investigate. Could you please check that both config files are the same in your two instances? And any chance we could get temporary view access to your instance by email at support att matomo.org ? Thanks
Hello Matt, What if in a first visit multiple requests to Piwik tracker are made as a same time?
I think we don’t have any thing to handle this concurrent issue. If the request are made as exactly the sametime, Piwik would create different visits for each request.
But for visit with different time it would might a different problem.
We installed the QueuedTracking plugin and the number of visits aligned much closer. I would say to an acceptable level. All numbers are off by a relatively small percentage (<2%), but it’s acceptable.
We manually reviewed the log and it appears the issue of simultaneous tracking requests creating multiple visits has gone away with QueuedTracking. We are still running both servers side-by-side and will continue monitoring.
I wonder if there are other high-traffic Websites out there that are significantly over-reporting their visits?
