Log file name - name of the log file and its location.
File size - size of the log file in kilobytes (and bytes).
File created - when the log file was created.

File accessed - when the log file was accessed.

Maximum log size - log file size will not exceed this value.
When maximum log size is reached:
Overwrite events as needed - when the log is full, the newest events will replace the oldest.
Overwrite events older then xx days - when the log is full new events will replace the old ones only if they are older then xx days.
Do not overwrite events (clear log manually) - if the log is full, you should clear it manually. Note that non-administrative users will not be able to logon if the log is full.
Backup log automatically, then clear it - log will be saved as a file and the emptied. See also: Automatic Event Log Backup.

Restore defaults - resets Event Log Size options to default values.
Clear Log - empties event log.
