Enable Network
Analyzer on
Select the port on which Network Analyzer observes traffic.
If you disable this option and log out, Network Analyzer will be
hidden in the web-based manager menu. For more information
about on re-enabling Network Analyzer and making it visible

.
Allocated Disk Space
(MB)
Enter the amount of disk space reserved for Network Analyzer
logs. The dialog also displays the amount used of the allocated
space.
When Allocated Disk
Space is All Used
Select what the FortiAnalyzer unit does when the allocated disk
space is filled up. Select to either overwrite the older log file or
stop logging until you can clear some room.
To avoid completely filling the hard disk space, use the log rolling
and uploading options.
Reuse settings from
standard logs
Select to use the same log rolling and uploading settings that you
set for standard logs files configured in Logs > Config.
Log rolling settings
Define when the FortiAnalyzer unit should roll its Network
Analyzer log files.
Log file should not
exceed
Enter the maximum size of each Network Analyzer log file.
When the log file reaches the specified maximum size, the
FortiAnalyzer unit saves the current log file with an incremental
number and starts a new active log file. For example, if the
maximum size is reached, the current xlog.log is renamed to
xlog.n.log, then a new xlog.log is created to receive new
log messages.
Log file should be
rolled... even if size is
not exceeded
Set the time of day when the FortiAnalyzer unit renames the
current log file and starts a new active log file.
•
Daily: Roll log files daily, even if the log file has not yet
reached maximum file size.
•
Weekly: Roll log files weekly, even if the log file has not yet
reached maximum file size.
•
Optional: Roll log files only when the log file reaches the
maximum file size, regardless of time interval.
