Website statistical analysis System Piwik (like Google Analytics), useful?

I configured the Piwik,php+mysql+apache on my own server (the company).
But I found that I only in my deployment of Piwik server to visit the target site, there will be statistical data, such as in other computers to visit the target site, there is no data into the Piwik, do not know how.
The firewall is also off Ah, is it a question of where to set? Solving...
Thank you

Do you not call Piwik's statistical code in the website that needs statistics?
You first study the use of Piwik, this is very elementary

You are talking about the generated JavaScript code, I have placed in the site I want to count, let's call this site to do a bar;
Now the problem is, I piwik on this server, open a browser to access a website, Piwik there will be statistics data;
However, when I use my own computer or other PC, to visit the site A, Piwik but there is no statistical data;

I also encountered this problem, I ask the landlord to solve it?

is the server address in the generated JavaScript code written in Locxalhost? Try to change to the actual address or domain name of the server
