This engine has originally been written to monitor Unix log files to detect intrusion attempts and prevent clients to continue guessing password or attempting exploiting the exposed services.

Library jar provided by this project are a framework (base class that you can extend) for implementing your own monitoring engine.

Also some example runnable applications are provided.

It can monitor resources (files, urls, etc) and based on events on that resources trigger some actions. You can monitor a website from events on which you are interested and make the software do something for you. For example, I implemented an automatic moderation engine that removes spam and unwanted messages from a public forum.
