Sample log events:
Apr 11 12:14:15 192.168.1.1 router %MIKROTIKFW: mangle-pre prerouting: in:bridge out:(none), src-mac 00:0c:29:58:2d:aa, proto TCP (ACK), 192.168.1.15:59231->188.8.131.52:443, NAT (192.168.1.15:59231->184.108.40.206:59231)->220.127.116.11:443, len 52
In order to configure the parser, you need to add a log-prefix to all messages sent, setup a logging action (destination of where events need to be sent) and finally configure which topics get associated with the logging action.
Mikrotik Syslog Configuration:
/system logging action set 3 bsd-syslog=yes remote=LOG.DECODER.IP.HERE syslog-facility=syslog syslog-severity=notice syslog-time-format=iso8601
/system logging add action=remote prefix=%MIKROTIKFW topics=firewall
For more information on configuring logging within RouterOS, please refer to the Mikrotik WIKI (Manual:System/Log - MikroTik Wiki).
Do not change the prefix. The attached parser requires "%MIKROTIKFW"!!
