"LogMX" stands for "Log" and "Massively eXtensible". Initially, this software was named "Tracy" (for "trace"), but several reasons lead to this renaming:


After "Tracy", the name "Loggy" came naturally, but was already used, too (by the U.S. army...). Finally, "LogMX" was chosen for its strong own identity, its reference to "log", and its nice 'sound'.

LogMX was first written by Xavier Tello, a young French IT engineer for Airbus, for personal purpose: Chainsaw and LogFactor tools didn't seem intuitive, nice, and powerful enough to him. Then, some new features were added every time they were needed. LightySoft company was then created to make LogMX available on the Internet.
Thanks go to (most are Atos Origin co-workers): Guillaume Castaignau, Cecile Berthelier, Vincent Tomasi, and the CMS team. Special thanks to Stephane Besseau and Christophe Busquet for their help in testing LogMX and their fresh ideas, and to Sébastien Estienne for helping making LogMX known to general public and professionals.
