sagan - Real-time System & Event Log Monitoring System

sagan [options]

This manual page documents briefly the sagan command.

sagan is a multi-threaded, real time system- and event-log monitoring system, but with a twist. Sagan uses a “Snort” like rule set for detecting malicious events happening on your network and/or computer systems.
If Sagan detects a potentially bad event, that event can be stored to a Snort database (MySQL/PostgreSQL), send it to a SIEM tool like Prelude, or send an email.
Sagan is meant to be used in a ‘centralized’ logging environment, but will work fine as part of a standalone Host IDS system for workstations.

These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below.
