| PackageDescription | network-wide graphing framework (node)
Munin is a highly flexible and powerful solution used to create graphs of
virtually everything imaginable throughout your network, while still
maintaining a rattling ease of installation and configuration.
.
This package contains the daemon for the nodes being monitored. You should
install it on all the nodes in your network. It will know how to extract all
sorts of data from the node it runs on, and will wait for the gatherer to
request this data for further processing.
.
It includes a range of plugins capable of extracting common values such as cpu
usage, network usage, load average, and so on. Creating your own plugins which
are capable of extracting other system-specific values is very easy, and is
often done in a matter of minutes. You can also create plugins which relay
information from other devices in your network that can't run Munin, such as a
switch or a server running another operating system, by using SNMP or similar
technology.
.
Munin is written in Perl, and relies heavily on Tobi Oetiker's excellent
RRDtool. To see a real example of Munin in action, you can follow a link
