Fireparse is a firewall log parsing tool. It parses the syslog and extracts the firewall related events to a separate file. It then generates an email (text or html) or an html output file providing a summary of relevant events. By default, the messages are removed from the syslog messages file, making it somewhat less cluttered.
The iptables version of Fireparse requires a particular syntax in the log-prefix of logged events. Selected this option generates a script that records the logged events in that format. The default is to record log events in a more readable format. Select this option if you intend to use Fireparse.
