You want to get notified is something goes weird on a web site you develop and that should be running 24/7?
Given a list of url, you want to check if they exist and send receive an email in case of trouble.
The problem is so common and hundreds of solutions exists on the web, from simple crontab shell to more complex system (hyperic & co).
We propose here one more system. The constraints were:
- check availability of url, response time or contents,
- get email to be notified in case of failure,
- a simple configuration system.
