Periodic Rotating File Handler Configuration

The rotation period is inferred based on the "suffix" value. The "suffix" is a string that can be parsed with java.text.SimpleDateFormat. The rotation period is the shortest identified amongst the following:

  • yearly if the suffix string contains "y".
  • monthly if the suffix string contains "M".
  • weekly if the suffix contains "w" or "W".
  • daily if the suffix contains "D", "d" "F" or "E"
  • half day if the suffix contains "a", "H", "k" or "K"
  • hourly if the suffix contains "h"
  • every minute if the suffix contains "m"

Seconds and milliseconds are not supported.
