Log files and types – FortiOS 6

Log files and types

As the log messages are being recorded, log messages are also being put into different log files. The log file contains the log messages that belong to that log type, for example, traffic log messages are put in the traffic log file.

When downloading the log file from within Log & Report, the file name indicates the log type and the device on which it is stored, as well as the date, time, and a unique id for that log.

This name is in the format <logtype> – <logdevice> – <date> T <time> . <id>.log.

For example, AntiVirusLog-disk-2012-09-13T11_07_57.922495.log.

Below, each of the different log files are explained. Traffic and Event logs come in multiple types, but all contain the base type such as ‘Event’ in the filename. Log Types based on network traffic
