php - multiple user, single website analytics -

I am developing a web application that has many users, it is basically an ecommerce system where many vendors Sell ​​

Now I need to use analytics how customers come, and how they flow.

I have to give a separate account (i.e., analytics account) Each vendor can also get that tracking code on the vendor's website so they can track the customers coming from their website. (Like funnel)

For example:

Land on customer vendor site - & gt; A specific product - & gt; Find product page - & gt; Click the More details button - & gt; Land on eCommerce Application - & gt; See product details - & gt; Decides to buy

Now, the seller will place the tracking code on their website, or webpage. The same code will be attached to the eCommerce application.

I need to know if such an Analytics Plugin / Application is available or not?

Thanks

If you have access to a web server, You can use log file analysis differently on each site's logs, then create accounts to view statistics for your clients, their respective stores on your server, on your server, installing something like AdWords, your customers To create an account and to parse the access log on a regular basis Crypt will include more.

You can also go with something like Piwik, and install it on your server once you have installed, create accounts and attach the required scripts to the store, then your customers will get the account information Give them so that they can analyze their site on their own holidays.
