Two (or more) Matomo instances can monitor the same website?

[jltest]

Hello,

I’m a website developper. For each one, I install Matomo along on my client host for he can monitor his site himself.

Is it possible I monitor all this websites in my own Matomo instance too ?

Thanks.

Hi,

It will work, but you can’t just paste both tracking codes into the site.

There is an extensive manual:

That’s it. Thank you.
