munin is definitely a very useful tool and I think using it with the
Kolab server makes a lot of sense.

Adding it to the set of features provided by the core Kolab server is
a different thing though. We'll get the same problem as with grey
listing: The Kolab server already has a rather large set of features
that is hard to support in its entirety. Each extra application would
add a good deal of additional features that would also need testing
and support. Given the current man power behind the project we should
definitely be careful about that.

That being said I believe we need a good extension/plugin possibility
that allows to provide such additional features/applications.

And the good news: I'm pretty certain I found a nice solution that
even accommodates for the fact that we are all working with Kolab on
different distributions. I'm currently testing it with Kolab2/Gentoo
and will propose it as an alternative to the current kolabconf if
testing looks promising.

Cheers,

Gunnar
