Qmrtg is a modular tool to help monitoring the
activity of software processes. It's intended to be
used with MRTG. It was originally written for monitoring qmail servers, but its modules are general enough to parse any kind of log file passed through multilog (see daemontools). QMRTG is modular. Each module carries out a different log analysis. A super-module lets the user easily request any analysis without having to know anything about the modules themselves. QMRTG is a modern alternative to qmailmrtg7.
