Description
This article describes the steps necessary to delete, download or review the log files for a specific device.
Scope
FortiAnalyzer.
Solution
Log files for a particular device can be deleted, downloaded, imported, or reviewed by using either the GUI or CLI.
From the GUI:
- Go to FortiAnalyzer -> Logview -> Log Browse.
- Select the log file for the device to delete.
- Select 'Delete, Download, Import or Display'.
From the CLI:
The below command lists the Device ID and the total size of logs for that device:
execute log device logstore list
The below command deletes all logs for that device:
execute log device logstore clear <device_id>
Another way to review the space used and what kinds of files are saved in the CLI is by using access to the filesystem through the shell.
Note:
Shell access was removed starting FortiAnalyzer v7.2.6, v7.4.4, and v7.6.0.
config system admin setting
set shell-access enable
Enter new password: *****
Confirm new password: *****
end
execute shell
bash$ cd /Storage/Logs/FGVM01TMxxxx/
bash$ pwd
/Storage/Logs/FGVM01TMxxxx
bash$ du -sh
22.8M .
To review how much space is taken by the logs on the HDD:
bash$ du
4 ./root/csf
12 ./root/.info
356 ./root/archive/1684013056
344 ./root/archive/1686110208
