Server Monitoring mit munin
Munin is a tool for graphing all sorts of information about one or more servers and displaying it in a web interface. It uses the execellent RRDTool (written by Tobi Oetiker) and is written in Perl. Munin has a master/node architecture. The master connects to all the nodes at regular intervals, and asks them for data. It then stores the data in RRD-files, and (if needed) updates the graphs. One of the main goals has been ease of creating own “plugins” (graphs). Quelle: http://www.linpro.no/projects/munin/

In Debian besteht leider keine automatische Abhängigkeit zum libwww-perl Paket, so dass die Apache-Monitoring Skripte zunächst nicht funktionieren. Abhilfe schaffen folgende Befehle:
libwww installieren
apt-get install libcrypt-ssleay-perl libwww-perl perl -MLWP -e 'print $LWP::VERSION' perl -le 'use LWP; print join "\n", grep /LWP/, keys %INC;'
