JoomlaWatch works just fine. Easy to install and ready in minutes. Publish a small module and component immediately start to display statistic in realtime. I just use it in back end but front module looks and works just fine too.

2 min and it's up. Simple and do the fine job.

Very neat plugin and great support form author.
Ideal for php snippets and quick short php code insertions in articles.

Working excellent with easy install and fantastic documentation. Highly customizable, from appearance to content. Tested in FF 3.5.3 IE8 and Chrome.
The speed is too fast in chrome, though it scroling nice in other 2 browsers.
