Is there a pixel tracking system for MODX ?

Hi everyone ?

I was just wondering if there is any pixel tracking system for modx ?

I mean by that, the possible of tracking external page ( from other websites) and getting stats into modx.

If not, do you know any software that can do the job ?


Thanks for your answers.

I know there is a piwik module for MODX, but I didnt use it yet. I use an external piwik service.
