Projects / LMon


LMon is a package for near real-time monitoring of logs, sending email alerts upon known (rule hits) or unknown data (rule misses). It features buffering of multiple rule hits within a given interval, cap at a given maximum number of lines, wait for a given interval before sending next alert, and auto- discovery of log rotation. It can be run from the command line without configuration, or be controlled from a central configuration file with multiple instances monitoring different log files/sending alerts to different people.
