NETMAN - Network Management System
I'm not happy with lots of the management/monitoring systems in the world. Some of them look pretty but don't do much other than ping hosts, some are expensive and overcomplicated frameworks, and others claim them work "out of the box".
Two things irritate me - having the same unreplicated data in multiple locations, and being unable to get exactly the right level of reporting. I've written many plugins, backends and subsystems for NETMAN. One day, I'll get screenshots, source code and documentation on the web.
