Apache Tip - Realtime view of user access

In preparation for an upcoming post on running a webserver on your BeagleBoard/PandaBoard I stumbled across a handy tip with Apache.

If you are running a default Apache install under Ubuntu you can monitor the access of that webserver in realtime with the following command:

"tail -f /var/log/apache2/access.log"

This will automatically update the output in realtime (or close enough for a webserver)

There are other ways to do it with watch for example but this is the easiest way I found to show just the relevant information.
