SEC – Simple Event Correlator
SEC is a tool for accomplishing event correlation tasks in the domains of log analysis, system monitoring, network and security management, etc. Event correlation is a procedure where a stream of events is processed, in order to detect (and act on) certain event groups that occur within predefined time windows. Unlike most other event correlation products which are heavyweight solutions, SEC is a lightweight and platform-independent event correlator which runs as a single process.
SEC reads lines from files, named pipes, or standard input, matches the lines with patterns (like regular expressions or Perl subroutines) for recognizing input events, and correlates events according to the rules in its configuration file(s). SEC can produce output by executing external programs (e.g., snmptrap or mail), by writing to files, by calling precompiled Perl subroutines, etc.
