Cron Scheduler

The Cron Scheduler allows you to schedule monitoring tasks using cron-like expressions. It supports five fields: minute, hour, day of month, month, and day of week.

Fields

Field	Range	Description
Minute	0-59	The minute of the hour when the task should run.
Hour	0-23	The hour of the day when the task should run.
Day of Month	1-31	The day of the month.
Month	1-12	The month of the year.
Day of Week	Monday-Sunday or Any	The day of the week.

Next Execution

The Cron Scheduler calculates the next execution time based on the current date/time (using the local time zone). If no matching time is found within a 5-year window, the scheduler returns an invalid date and the task will not execute.

Examples

Expression	Meaning
Minute=0, Hour=9	Every day at 9:00 AM
Minute=30, Hour=14, Day=1	First day of every month at 2:30 PM
Minute=0, Hour=8, WeekDay=Monday	Every Monday at 8:00 AM
Minute=0, Hour=8, WeekDay=Monday, Day=1	Every Monday at 8:00 AM OR Every first day of the month at 8:00 AM
Day=31, Month=2	Will not schedule, since Februrary has only 28/29 days
