Awesome!!
I'm a developer of the Pandora Free Monitoring System,
( http://pandora.sf.net ), and I'm currently developing some native modules
for PandoraFMS to keep monitorice LVS, most likely in bash.
This project will help me a lot and will give me some tricks, for sure :-)
I'll try to contribute to the ipvsman as much as I can :-)
Keep in touch
Best Regards
