From project website:
"Munin the monitoring tool surveys all your computers and remembers what it saw. It presents all the information in graphs through a web interface. Its emphasis is on plug and play capabilities. After completing a installation a high number of monitoring plugins will be playing with no more effort.
Using Munin you can easily monitor the performance of your computers, networks, SANs, applications, weather measurements and whatever comes to mind. It makes it easy to determine "what's different today" when a performance problem crops up. It makes it easy to see how you're doing capacity-wise on any resources."
The configuration file is:
The minimal configuration file for server:
# Configfile for Munin master dbdir /var/lib/munin/ htmldir /var/www/munin/ logdir /var/log/munin rundir /var/run/munin/ [mynode.mydomain.com] address 192.168.1.105
In the configuration file for server I specified only one single node: mynode.mydomain.com
Next step is to configure the node but the default configuration is fine, only let the server to acces Munin port 4949:
where 192.168.1.1 is the ip number for server.
The final step si to check their website to read the documentation/faq for more configuration options.
