If log rotation is enabled, the log_file_size parameter determines the log file size threshold at which the log is automatically rotated.

• "unlimited" or "0" (default) - the feature is disabled
• "default" - default size is used (4Mb)
• <size>[KMG] - size of the current log file in bytes with additional multipliers:

  • K - Kilobyte - multiply by 1024

  • M - Megabyte - multiply by 1024*1024

  • G - Gigabyte - multiply by 1024*1024*1024

Examples:

 Minimum log file size is 64K, maximum is 1G. Setting size less then 64K effectively makes the log file unlimited.

• <period-in-seconds>

Defines a period of flushing log to disk.

Default period is 60 seconds (it means that every minute log file is flushed to disk)
