Displays the permissions of the device for sending and viewing logs and
reports.
• Tx indicates the FortiGate unit is configured to transmit log packets to
the FortiAnalyzer unit.
• Rx indicates the FortiGate unit is allowed to view reports and logs
stored on the FortiAnalyzer unit.
A check mark indicates the FortiGate unit has permissions to send or view
log information and reports. An X indicates the FortiGate unit is not allowed
to send or view log information.
You can also test the connection status between the FortiGate unit and the
FortiAnalyzer unit by using the following CLI command:
execute log fortianalyzer test-connectivity
The command displays the status and the amount of disk usage in percent. See
the FortiGate CLI Reference for more information.
Note: In FortiOS 3.0MR5, the test connectivity feature also provides a warning when a
FortiGate unit requires a higher-end FortiAnalyzer unit.
Logging to memory
The FortiGate system memory has a limited capacity for log messages. It displays
the most recent log entries. The FortiGate unit does not store Traffic and Content
logs in memory due to their size and frequency of log entries. When the memory
is full, the FortiGate unit overwrites the oldest messages. All log entries are
cleared when the FortiGate unit restarts.
If your FortiGate unit has a hard disk, use the CLI to enable logging to the
FortiGate hard disk. You can also upload logs stored on the hard disk to a
FortiAnalyzer unit. See the FortiGate CLI Reference for more information.
To configure the FortiGate unit to save logs in memory
1 Go to Log&Report > Log Config > Log Setting.
2 Select Memory.
3 Select the blue arrow to expand the Memory options.
4 Select the severity level.
The FortiGate unit logs all messages at and above the logging severity level you
select. For details on the logging levels, see Table 44, “Log severity levels,” on
page 471.
