Log message fields
Each log message consists of several sections of fields. In the FortiOS GUI, you can view the logs in the Log & Report pane, which displays the formatted view. If you want to view logs in raw format, you must download the log and view it in a text editor.
Following is an example of a traffic log message in raw format:
date=2017-11-15 time=11:44:16 logid="0000000013" type="traffic" subtype="forward" level="notice" vd="vdom1" eventtime=1510775056 srcip=10.1.100.155 srcname="pc1" srcport=40772 srcintf="port12" srcintfrole="undefined" dstip=35.197.51.42 dstname="fortiguard.com" dstport=443 dstintf="port11" dstintfrole="undefined" poluuid="707a0d88-c972-51e7-bbc7-4d421660557b" sessionid=8058 proto=6 action="close" policyid=1 policytype="policy" policymode="learn" service="HTTPS" dstcountry="United States" srccountry="Reserved" trandisp="snat" transip=172.16.200.2 transport=40772 appid=40568 app="HTTPS.BROWSER" appcat="Web.Client" apprisk="medium" duration=2 sentbyte=1850 rcvdbyte=39898 sentpkt=25 rcvdpkt=37 utmaction="allow" countapp=1 devtype="Linux PC" osname="Linux" mastersrcmac="a2:e9:00:ec:40:01" srcmac="a2:e9:00:ec:40:01" srcserver=0 utmref=0-220586
