Yesterday I finally completed writing the documentation, and published my own reinvented wheel: Pyng.

Pyng is a daemon which runs checks and sends alerts on certain events. It is written in Python and uses Twisted event-driven networking engine for scheduling and retries, but uses existing command line tools for the dirty work.

I started on the project last year, primarily due to NodePing's DNS check limitations, and have been happily using Pyng ever since. I hope that others might find Pyng useful.

I consider Pyng finished software, i.e. it now has all the features I wanted from it.
