This is a simple hack that take a feed from one or more apache log files, and displays the 10 most accessed pages over the last 15 minutes.
This uses ZeroMQ, which is a native library you need to install.
On Ubuntu do this with:
sudo apt-get install libzmq0 libzmq-dev
The publisher bit uses ruby, so you'll also need to install the gem:
sudo gem install zmq
On my version on Ubuntu (11.10) I get an error message like:
Invalid gemspec in [/var/lib/gems/1.8/specifications/foreman-0.25.0.gemspec]: invalid date format in specification: "2011-10-17 00:00:00.000000000Z"
In which case you need to follow the instructions at on Stack Overflow:
sudo gem install rubygems-update
sudo update_rubygems
Note this will effectively uninstall all your gems, so you'll need to repeat the gem install command above.
We use Foreman to startup all the apps, so install that with:
sudo gem install foreman
Then startup with:
./start.sh
Which will run foreman start in an infinite loop. Now go to http://localhost:5000 and enjoy.
