+
+<p>One of the new features in the next Debian/Lenny based release of
+Debian Edu/Skolelinux, which is scheduled for release in the next few
+days, is automatic configuration of the service monitoring system
+Nagios. The previous release had automatic configuration of trend
+analysis using Munin, and this Lenny based release take that a step
+further.</p>
+
+<p>When installing a Debian Edu Main-server, it is automatically
+configured as a Munin and Nagios server. In addition, it is
+configured to be a server for the
+<a href="http://wiki.debian.org/DebianEdu/HowTo/SiteSummary">SiteSummary
+system</a> I have written for use in Debian Edu. The SiteSummary
+system is inspired by a system used by the University of Oslo where I
+work. In short, the system provide a centralised collector of
+information about the computers on the network, and a client on each
+computer submitting information to this collector. This allow for
+automatic information on which packages are installed on each machine,
+which kernel the machines are using, what kind of configuration the
+packages got etc. This also allow us to automatically generate Munin
+and Nagios configuration.</p>
+
+<p>All computers reporting to the sitesummary collector with the
+munin-node package installed is automatically enabled as a Munin
+client and graphs from the statistics collected from that machine show
+up automatically on http://www/munin/ on the Main-server.</p>
+
+<p>All non-laptop computers reporting to the sitesummary collector are
+automatically monitored for network presence (ping and any network
+services detected). In addition, all computers (also laptops) with
+the nagios-nrpe-server package installed and configured the way
+sitesummary would configure it, are monitored for full disks, software
+raid status, swap free and other checks that need to run locally on
+the machine.</p>
+
+<p>The result is that the administrator on a school using Debian Edu
+based on Lenny will be able to check the health of his installation
+with one look at the Nagios settings, without having to spend any time
+keeping the Nagios configuration up-to-date.</p>
+
+<p>The only configuration one need to do to get Nagios up and running
+is to set the password used to get access via HTTP. The system
+administrator need to run "<tt>htpasswd /etc/nagios3/htpasswd.users
+nagiosadmin</tt>" to create a nagiosadmin user and set a password for
+it to be able to log into the Nagios web pages. After that,
+everything is taken care of.</p>
