About schedules for running policies
A schedule is specified in a format similar to the UNIX crontab format. The format uses five fields to specify when the schedule runs:
minute | Enter a numeric value between 0-59, or an asterisk (*), which represents every minute. You can also enter a step value (*/x), or a range of numbers separated by a hyphen. |
hour | Enter a numeric value between 0-23, or an asterisk (*), which represents every hour. You can also enter a step value (*/x), or a range of numbers separated by a hyphen. |
day_of_the_month | Enter a numeric value between 1-31, or an asterisk (*), which represents every day of the month. You can also enter a step value (*/x), or a range of numbers separated by a hyphen. |
month | Enter a numeric value between 1-12, or an asterisk (*), which represents every month. You can also use the names of the month. Enter the first three letters of the month (you must use lower case letters). You can also enter a step value (*/x), or a range. |
day_of_the_week | Enter a numeric value between 0-6, where 0 represents Sunday, or an asterisk (*), which represents every weekday. You can also enter the first three letters of the week (you must use lower case letters). You can also enter a step value (*/x), or a range. |
A step value (*/x) specifies that the schedule runs at an interval of x. The interval should be an even multiple of the field's range. For example, you could specify */4 for the hour field to specify every four hours, since 24 is evenly divisible by 4. However, if you specify */15, you may get undesired results, since 24 is not evenly divisible by 15. The schedule would run after 15 hours, then 7 hours.
A range of numbers (two values separated by a hyphen) represents a time period during which you want the schedule to run.
Examples: To run the schedule every two hours every day:
0 */2 * * *
To run the schedule on 2:00 a.m. every Monday:
* 2 * * 1
To run the schedule at 11:15 p.m. every Saturday:
15 23 * * 6
