MRTG

Software Description

The Multi Router Traffic Grapher (MRTG) is a tool to monitor the traffic load on network links. MRTG generates HTML pages containing PNG images which provide a LIVE visual representation of this traffic.

You have a router, you want to know what it does all day long? Then MRTG is for you. It will monitor SNMP network devices and draw pretty pictures showing how much traffic has passed through each interface.

Routers are only the beginning. MRTG is being used to graph all sorts of network devices as well as everything else from weather data to vending machines.

Key features:

- Works on most UNIX platforms and Windows NT.

- Written in Perl and comes with full source.

- Uses a highly portable SNMP implementation written entirely in Perl (thanks to Simon Leinen). There is no need to install any external SNMP package.

- Can read the new SNMPv2c 64bit counters. No more counter wrapping.

- Router interfaces can be identified by IP address, description and ethernet address in addition to the normal interface number.

- MRTG's logfiles do NOT grow thanks to the use of a unique data consolidation algorithm.

- Comes with a set of configuration tools which make configuration and setup very simple.

- Time critical routines are written in C (thanks to the initiative of Dave Rand my Co-Author).

- Graphics are generated directly in PNG format using the GD library by Thomas Boutell.

- The look of the webpages produced by MRTG is highly configurable.

- MRTG has built-in hooks for using RRDtool. If you are strapped for performance this may help.

MRTG consists of a Perl script which uses SNMP to read the traffic counters of your routers and a fast C program which logs the traffic data and creates beautiful graphs representing the traffic on the monitored network connection. These graphs are embedded into webpages which 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 five 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 200 or more network links from any halfway decent UNIX box.

MRTG is not limited to monitoring traffic, though. 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 is written in perl and works on Unix/Linux as well as Windows and even Netware systems. MRTG is free software licensed under the Gnu GPL.
