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":/RRDTool RRDTool (written by Tobi Oetiker) and is written in "Perl":/Perl. 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).

"Munin is a system to gather and graph all sorts of

information. You can install a node on the various

machines in your network, as well as on a central

server. The nodes will know how to extract various

kinds of information, such as load average and

bandwidth usage, and will wait for the server to

request these values. The output is in HTML

format. The server can optionally send notifications if

any of the values move outside of a specified

range (and when they move back into it).
