Munin (Network Monitoring Application)
Encyclopedia
Munin is a network/system monitoring application that presents output in graphs through a web interface
. Its emphasis is on plug and play capabilities. About 500 monitoring plugins are currently available. Using Munin you can monitor the performance of your computers, networks, SAN
s, and applications. It tries to make it easy to determine "what's different today" when a performance problem crops up and to see how you're doing capacity wise on all limited resource
s.
It uses the RRDtool
(written by Tobi Oetiker) and is written in Perl
. Munin has a master/node architecture in which the master connects to all the node
s 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 new plugins (graphs).
User interface
The user interface, in the industrial design field of human–machine interaction, is the space where interaction between humans and machines occurs. The goal of interaction between a human and a machine at the user interface is effective operation and control of the machine, and feedback from the...

Storage area network
A storage area network is a dedicated network that provides access to consolidated, block level data storage. SANs are primarily used to make storage devices, such as disk arrays, tape libraries, and optical jukeboxes, accessible to servers so that the devices appear like locally attached devices...

Perl
Perl is a high-level, general-purpose, interpreted, dynamic programming language. Perl was originally developed by Larry Wall in 1987 as a general-purpose Unix scripting language to make report processing easier. Since then, it has undergone many changes and revisions and become widely popular...
