Tagr stands for Traffic Analizer and Grapher. It is a tool designed as a light-weight replacement for MRTG and similar tools. Tagr listens on a UDP port to receive traffic data packets generated by ipacct, computes statistics and generates corresponding graphs and html pages. The tool was originally created by Max Bouglacoff while we fiddled with ipacct project in Farlep. We were rather short of time, so Max borrowed the graphics part from the `rateup' program (MRTG) and managed to write the whole thing within a couple of hours. In his usual sarcastic (or was it cynic?) manner, he baptized it `taxcollector'. The tool was used successfully since then, and, despite its deficiences neither of us felt like cleaning it up. Its time came only when we have set up `ulysses', a Linux box that was to handle mirrors of gnu.org and TUHS (The UNIX Heritage Society) in Ukraine. All of a sudden we found ourselves in need to see the traffic consumption in real time, so I excavated `taxcollector' sources and rewrote it. All major parts of the program were improved, starting from the configuration file parser and up to the completely new grahics code. That's all folks!
