Description:
The Multi Router Traffic Grapher (MRTG) is a tool to monitor the
traffic load on network links. MRTG generates HTML pages
containing GIF images which provide a LIVE visual representation
of this traffic. See http://www.ee.ethz.ch/stats/mrtg/ for an
example. MRTG is based on Perl and C and works under UNIX and
Windows NT. MRTG is being successfully used on many sites arrond
the net.
MRTG consists of a Perl script that uses SNMP to read the traffic
counters of your routers and a fast C program that logs the
traffic data and creates beautiful graphs representing the
traffic on the monitored network connection. These graphs are
embedded into web pages that can be viewed from any modern web
browser.
In addition to a detailed daily view, MRTG also creates visual
representations of the traffic seen during the last seven days,
the last four weeks and the last twelve months. This is possible
because MRTG keeps a log of all the data it has pulled from the
router. This log is automatically consolidated, so that it does
not grow over time, but still contains all the relevant data for
all the traffic seen over the last two years. This is all
performed in an efficient manner. Therefore you can monitor 50 or
more network links from any halfway decent UNIX box.
MRTG is not limited to monitoring traffic, however. It is possible
to monitor any SNMP variable you choose. You can even use an
external program to gather the data which should be monitored via
MRTG. People are using MRTG to monitor things such as system
load, login sessions, modem availability and more. MRTG even
allows you to accumulate two or more data sources into a single graph.
MRTG highlights:
+ Works on most UNIX platforms and Windows NT
+ Uses Perl for easy customization
+ Has a highly portable SNMP implementation written entirely in
Perl thanks to Simon Leinen. There is no need to install any
external SNMP package.
+ MRTG's logfiles do NOT grow, thanks to the use of a unique
data consolidation algorithm.
+ MRTG comes with a semi-automatic configuration tool.
+ MRTG's query engine checks for port reconfigurations on the
router and warns the user when they occur.
+ Time-critical routines are written in C thanks to the initiative
of Dave Rand, my co-author.
+ Graphics are generated directly in GIF format using the GD
library by Thomas Boutell.
+ The look of the web pages produced by MRTG is highly configurable.
+ MRTG is available under the GNU PUBLIC LICENSE.
There are two mailing lists for MRTG available. One is called
'mrtg' and is a discussion list for users and developers. The
other is called 'mrtg-announce' and is a low volume list for MRTG
related announcements.
To subscribe to these mailing lists, send a message with the
subject line subscribe to either mrtg-request@list.ee.ethz.ch or
mrtg-announce-request@list.ee.ethz.ch. For posting to the mrtg
list use the address mrtg@list.ee.ethz.ch.
Further information about the usage of the mailing lists is
available by sending a message with the subject line 'help' to
either one of the request addresses.
For past activity there is also a mailing list archive available:
