Reference

If you select the schedule frequency as monthly, you must enter the schedule execution date, Date. Refer to the information below to register the schedule.

  • If you input a number greater than 0, it represents the day of the month.
    • Example: If you enter 1, you get August 1, September 1, …, December 1
  • If you enter a number less than 0, the calculation starts from the end of each month.
    • Entering -1 means the last day of each month.
      • Example: August 31, September 30, …, December 31
    • If you enter -2, it means the day before the last day of each month.
      • Example: August 30, September 29, …, December 30
    • Since the last day of each month varies—31, 30, 29, or 28 days—we allow calculation from the end of the month using negative numbers, as shown above, to handle schedules that need to run on the month’s final day.
Information
  • When the schedule runs, if the Min server count set in the schedule is greater than the Desired server count, or if the Max server count is less than the Desired server count, the Desired server count is also adjusted.
  • If there are schedules with overlapping execution times, they may not run correctly. Please try to avoid overlapping execution times as much as possible.
