FortiOS Log Message Reference

Enabling extended logging

You can enable extended logging for the following UTM profiles:

  • antivirus
  • application
  • dlp
  • ips
  • waf
  • webfilter

When you enable the extended-log option for UTM profiles, all HTTP header information for HTTP-deny traffic is logged.

When you enable the web-extended-all-action-log-enable option for webfilter profile, all HTTP header information for HTTP-allow traffic is logged.

Extended logging option in UTM profiles

The extended-log option has been added to all UTM profiles, for example:

# webfilter profile

config webfilter profile

edit "test-webfilter"

set extended-log enable

set web-extended-all-action-log enable

next

end

# av profile

config antivirus profile

edit "av-proxy-test"

set extended-log enable

next

end

# waf profile

config waf profile

edit "test-waf"

set extended-log enable

next

end

Syslog server mode

The Syslog server mode changed to udp, reliable, and legacy-reliable. You must set the mode to reliable to support extended logging, for example:

config log syslogd setting

set status enable

set server "<ip address>"

set mode reliable

set facility local6

end

Example of an extended log

Following is an example extended log for a utm log type with a webfilter subtype for a reliable Syslog server. The rawdata field contains the extended log data.
