Log-related diagnose commands

This topic shows commonly used examples of log-related diagnose commands.

Use the following diagnose commands to identify log issues:

• The following commands enable debugging log daemon (miglogd) at the proper debug level:

  diagnose debug application miglogd x
  diagnose debug enable

• The following commands display different status/statistics of miglogd at the proper level:

  diagnose test application miglogd x
  diagnose debug enable

To get the list of available levels, press Enter after diagnose test/debug application miglogd. The following are some examples of commonly use levels.

If the debug log display does not return correct entries when log filter is set:

diagnose debug application miglogd 0x1000

For example, use the following command to display all login system event logs:

execute log filter device disk
execute log filter category event
execute log filter field action login

execute log display

You can check and/or debug the FortiGate to FortiAnalyzer connection status.

To show connect status with detailed information:
