My understanding of the matomo_log_link_visit_action table is that it’s a list of actions taken, and the visit they are attributable to.
The columns idvisit and idvisitor identify the visit this action happened in (and the user of that visit)
Why then, do I see in this table, multiple users associated with the same visit?
We don’t do any ip anonymization, and we (where we can identify them) use userIDs.
How did you configure:
I have the same problem. I want to to confirm whether the same visit only respond to a unique user
Most of the time, a single visit ID and also a single visitor ID should respond to a unique user. But this can be wrong in some misconfiguration of Matomo.
Same browser configuration + IP (eg. users belonging to the same company, who have same computer types and use the same outgoing IP of with a proxy misconfiguration on your side) with no cookie tracking could be interpreted by Matomo as the same user…
@scamp, can you compare the rows displayed in your first post with the raw data Matomo used to track? (either server log or Matomo verbose log)
We have the same issue and are investigating this with Matomo support.
A not logged-in user has a visit, then he logs in and gets a new visit. And when he logs out he returns to the first visit. So it seems like there is something going wrong with merging the before and after visits to one visit.
(We already fixed the after logout by getting the userid differently, but that’s only a work around and not a good fix).
