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

General questions

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:

Hi ! What if the two instances are not configured the same ? I tried to use this method :

window.matomoAsyncInit = function () {
    // will never issue an HTTP request to configs.php for this Matomo instance
    	var tracker = Matomo.getAsyncTracker('siteUrl/matomo.php', 21);
   		if (tracker.HeatmapSessionRecording) {
        tracker.HeatmapSessionRecording.disable();
    	}
};

But still I can see request to the config.php file. How can I do ? (one server is RGPD compliant and the other is not).

Finaly when I use matomoHeatmapSessionRecordingAsyncInit instead of matomoAsyncInit It works on the tracker…
