FortiOS Log Message Reference

Anomaly log support for CEF

The following is an example of an anomaly log on the FortiGate disk:

date=2018-12-27 time=11:40:04 logid="0720018433" type="utm" subtype="anomaly" eventtype="anomaly" level="alert" vd="vdom1" eventtime=1545939604 severity="critical" srcip=10.1.100.11 srccountry="Reserved" dstip=172.16.200.55 srcintf="port12" srcintfrole="undefined" sessionid=0 action="clear_session" proto=1 service="PING" count=1 attack="icmp_flood" icmpid="0x3053" icmptype="0x08" icmpcode="0x00" attackid=16777316 policyid=1 policytype="DoS-policy" ref="http://www.fortinet.com/ids/VID16777316" msg="anomaly: icmp_flood, 51 > threshold 50" crscore=50 crlevel="critical"

The following is an example of an anomaly log sent in CEF format to a syslog server:
