1. What is PSI - PHP Simple Informer ?
   It's a very simple and basic network services monitoring application. It can check tcp ports for the moment.
2. Why is written in PHP ?
   Because it's a great scripting language and I love it! Simple, fast to write and very powerful! More info at http://www.php.net
3. Why another network services monitoring program ?
   Because all of the available applications are more complex that what I need or they don't perform so simple tasks. I don't know if this application is useful for anybody, but it is for me.
4. When I set to receive alters by emails, I never receive them. Check that PHP is properly configured to use a mail delivery system (sendmail?) in the php.ini file. Test the following quick script to see if PHP sends emails correctly: And watch your email log files to see if the email is sent correctly.
5. Why this page sucks?
   Because I don't have time to put it better.

If I get spare time, I will add more features like:

• Add additional special services.
• Logging to a file or maybe a DB to have a history and be able to make graphics (partially implemented).
• Create a webpage to check the status (done, maybe enhanced). -
• Create a web-based administration interface (pending).
• Any more ideas? Email me!
