There are a lot of tools out there that can analyze web traffic for your site. Leading the pack is Google Analytics. But what if you want statistics of your internal website, and you don’t necessarily want to send this information to an external provider such as Google? Here comes Piwik.  Piwik is very much like Google Analytics but can be installed on your internal network. The best part is that it’s free.

Since Piwik is a downloadable tool, you need to have a machine running web server and mysql. You can install it on your existing web server or on a separate web server. I installed it on a separate CentOS machine. I found the installation very easy. In fact, you just unzip a file and put those files in a web directory. The rest of the installation is via the browser. If there is a tool missing on your server, (in my case, I need the PDO extension) it will tell you how to install it. Pretty neat.

After installing the server, you just need to put a small javascript code on the pages you want to track. That’s it. Piwik will start gathering statistics for your site.

I also evaluated Splunk and it’s companion app – Splunk App for Web Intelligence, but I found that it is not ready for prime time. There are still bugs. No wonder it is still in beta. When I was evaluating, it wasn’t even able to get usable information from apache logs.

I’ve been using Awstats to extract statistics for internal websites for years. It has been very reliable but sometimes it provides inaccurate results. The open source Piwik web analytic tool provides accurate statistics and is the best tool I’ve used so far.
