Thanks for the report @brenc It is indeed problematic and not good enough as it is now, as it's confusing and not clear, and many users like you don't expect this behavior. The issue is that some users want the behavior of considering all alias URLs as pointing to the same site (and merging them together), while others (like you) prefer to keep them separate.

Maybe this is something we could address in Matomo 4.x?

Not needed for Matomo 4. This can be done any time later.

Hello.
Have a same issue with mixing of page urls which become from all subdomains, but they are logically separated from "main" and other domains, and may have different pages. What I can do at this moment to separate page urls? Maybe just add a "subdomain" to page url variable (like in Google Analytics) or something like this? I can write own code if it needed, but want to get some info about where to start with that problem.

Hi @breaked01 , if you mean separate them in the Actions report, there's not much you can do at present. The change isn't that big though, so I created a poc in this PR: #17203

If acceptable it might be able to go in the next release.

@diosmosis not sure I fully understand the PR correct but thinking as it's done in archiving, might need to add a comment that this will cause maybe issues when looking at week, month, year, ... that some will have the host while some rows won't and it'll be all mixed maybe?

yeah, that would be an issue. the easiest way around this might be to make the setting unchangeable. otherwise, if we see both types when aggregating we can group by host in the one that includes host, then aggregate w/ the one w/ no host. there's no way to go from no-host to host though so that's the best we can do I think.

OK @diosmosis I guess we would just need to mention this in the comment for the config and also when we explain this new feature in an FAQ.

There is already #17203 which looks like a good setting in the config to enable subdomains in the configuration. Unfortunately it was closed. Still waiting for it to be merged.

I think this is fine like any other setting (like the number of entries in subtables). If you change those settings you have to invalidate all reports and recreate them. When you setup Matomo you do this quite often.

This setting looks like something that people won't set all the time. It would be done by people who have subdomains with meaningful names and different content. Those people only having "www.example.org" and "example.org" would never enable this.

Maybe theres a way to automatically strip the "www." during reporting like at other places of Matomo.
