stop logging until you can clear some room.

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.
