Select a view of the log file. Selecting Formatted (the default) displays the log files in columnar format. Selecting Raw, displays the log information as it actually appears in the log file.

Select to display host names by a recognizable name rather than IP addresses. For more information about on configuring IP address host names see “Configuring IP aliases” on page 61.

Select to display the network service names rather than the port numbers, such as HTTP rather than port 80.

This option does not appear when the logs do not have service information to display, which can occur in the event log.

Select the number of rows of log entries to display per page. Enter a log page number, then press Enter to go to that page.

Select to change the columns to view and the order they appear on the page. For more information, see “Displaying and arranging log columns” on page 97.

Enter a keyword to perform a simple search for that term, then select Go to begin the search. The FortiAnalyzer unit searches the entire log file for the keyword you enter. The number of matches appears above the Search field.

Select to download an HTML file containing all log messages that match the current filters. The HTML file is formatted to be printable.

Time required to generate and download large reports varies by the total amount of log messages, the complexity of any search criteria, the specificity of your column filters, and the speed of your network connection.

Select to download only those log messages which are currently visible, according to enabled filters.

This button only appears when the current log view is filtered. The downloaded version will match the current log view, containing only log messages that match your current filter settings.

Importing a log file

You can import devices’ log files. This can be useful when restoring data or loading log data for temporary use.

For example, if you have older log files from a device, you can import these logs onto the FortiAnalyzer unit in order to generate reports on older data. Importing log files is also useful when changing your RAID configuration. Changing your RAID configuration reformats the hard disk, erasing log files. If you back up the log files, after changing the RAID configuration, you can import logs to restore them to the FortiAnalyzer unit.

You can import logs in normal log, compressed log (.log.gz) or comma separated value (CSV) format.

1Go to Log > Browse.

2Select the Device Type.

3Select Import.

4Select from Device to which device in the device list the imported log file belongs, or select Take From Imported File to read the device ID from the log file.

If you select Take From Imported File, your log file must contain a device_id field in its log messages.
