So let's hear the news first: * The rrdtool integration allows for massively increased logging performance. * Routers which change their interface numbers are no problem any more. MRTG can now reliably address interfaces by IP, MAC, Description, Name and Type. The cfgmaker tool has been rewritten from scratch and allows to generate configurations with any of the above mentioned interface addressing methods. * Indexmaker has be rewritten from scratch, it is now much more flexible and fully documented. * All the MRTG documentation has been reviewed and ported to perls "Plain Old Documentation (POD)" format. This allows to provide all documentation in text, HTML and man format. It is now all available on the MRTG web-site. * Config file parsing has been optimized. This makes reading configuration files much faster. Especially large configuration files are faster by factors * Under UNIX, mrtg can fork into several instances while querying routers. This improves data acquisition performance dramatically, especially with slow networks. * Graphs and webpages can be generated on the fly is mrtg is used with rrdtool logging. Several tools in the mrtg contrib section are available for this purpose. * And there is more: MRTG has been translated into 29 languages, OS detection has been automated, did I mention performance, many of the contributed tools have been dated and a slew of new ones has been added, The config file reading code is now available in a documented library which simplifies the creation of other tools which need access to the mrtg cfg file. * In total, over 200 individual changes are listed in the change log since the release of MRTG 2.9.17. DESCRIPTION =========== The Multi Router Traffic Grapher (MRTG) is an open-source tool to monitor the traffic load on network-links. MRTG generates HTML pages containing Web Graphics which provide a LIVE visual representation of this traffic. Check http://www.stat.ee.ethz.ch/mrtg/ to see what it does. 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. Mrtg is known to work on most UNIX variants as well as on NT.
