munin

[Richard Bos]

Hi,

this week I have installed an application called munin.  It is a (from the 
website) monitoring tool to survey all your computers and remembers what it 
saw. It presents all the information in graphs through a web interface.  
(more information at: http://munin.projects.linpro.no/ and look for about 
munin).

I like the way it present the information, but even more the easiness of 
installation.  On openSUSE the only thing I needed to do, was to install the 
rpms (the package manager took care of the dependencies ;) ).

With Munin this idea
http://wiki.kolab.org/index.php/Soc_2006#Kolab_centralized_log_management_and_analisys
 is implemented :)

Although I don't have the figures yet for amavis, clamav, openldap and 
spamassassin (did I forget a service?).  However, I just discovered munin 
exchange: http://muninexchange.projects.linpro.no/
It has plugins for clamav, openldap and amavis.  I'll soon install the 
openldap one.  Unfortenately a plugin for cyrus is missing.  Does anyone now 
how to obtain figures of cyrus' performance?  Does someone have a cyrus 
plugin for munin?

Last: I think that munin would be a great application to add to the kolab 
server, especially when it comes with the additional plugins for the services 
that are used by kolab.  I think that it would be rather easy to even 
configure (add) slaves automatically to the config file of the main munin 
host (using kolab's template mechanism).  If intergrated, it would be nice it 
it is part of kolab manager login.

Example munin output: http://munin.ping.uio.no/

Just to let you know, that this application exists and seems usefull to kolab 
admins.
