CRON expressions for policy probe schedules

Many Data Collector policy configurations require a schedule. Native CRON expressions are supported for fine-tuning a schedule. The CRON expression format for the policy configurations follows strings with five single space-separated time and date fields:

*

minutes

 

*

hours

 

*

day of month

 

*

month

 

*

day of the week

The following are the general guidelines when using special characters during the CRON expressions.

Table: Probe Schedule Allowed Values and Allowed Special Characters

Field

Allowed Values

minutes

0-59 (0 is "on the hour")

hours

0-23

day of month

1-31

month

1-12

day of week

0-6 (0 is Sunday)

  • NetBackup IT Analytics supports a maximum of 80 characters in a CRON expression.

Special Characters:

  • A field may be an asterisk (*), which means the full range - i.e., "first" to "last". However, a * in the seconds and minutes position is not permitted, as this would excessively trigger the probe - every second or minute.

  • A forward slash (/) can be used to specify intervals.

  • Use a dash (-) to specify a range.

  • The CRON expression for the last day of the month, denoted by the letter L, is not supported.

Probe Schedule Examples

Scheduled Run Time

0 14-15 * * 1

On the hour, every Monday, between 2 and 3pm

Note:

A zero in the minutes position denotes the beginning of the hour.
