Probe Schedule Examples
Many Data Collector policy configurations require a schedule. Native CRON expressions are supported for
fine-tuning a schedule. The format for the schedule follows the CRON standard:
*
minutes
*
hours
*
day of month
*
month
*
day of week
Probe Schedule Allowed Values:
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
0-7 (0 or 7 is Sunday)
Special Characters:
A field may also be an asterisk (*), which means the full range - i.e., “first” to “last”. However, a * in the minutes position is not permitted, as this would excessively trigger the probe—every minute.
Use a dash (-) to specify a range.
