I've recently discovered Shinken, which is a new implementation of Nagios using python. Shinken "divides" Nagios in 5 different types of daemons, each one performing separated tasks. I haven't tried it yet but for what I've seen the whole architecture idea seems great to me (it works the Unix way: one process, one task), but the project seems a little "green" yet.
So, has anyone tried Shinken? What's your opinion?
