Hello

I am having an issue when scheduling some reports which i set cron as : 0 6 3 * * which is “At 06:00 on day-of-month 3." but when i see the next schedule it shows as daily at 06:00, for example it shows that is scheduled for tomorrow 22/01/2020 at 06:00

Add a scheduled task
The layout for a cron entry is made up of six components: minute, hour, day of month, month of year, day of week, and the command to be executed.

m h dom mon dow command

* * * * * command to execute

┬ ┬ ┬ ┬ ┬

│ │ │ │ │

│ │ │ │ │

│ │ │ │ └───── day of week (0 - 7) (0 to 6 are Sunday to Saturday, or use names; 7 is Sunday, the same as 0)

│ │ │ └────────── month (1 - 12)

│ │ └─────────────── day of month (1 - 31)

│ └──────────────────── hour (0 - 23)

└───────────────────────── min (0 - 59)

Hi. What version of Splunk are you running?

I can't find anything in the release notes about your issue but I see someone else had a similar problem with Splunk 7.2.x

Is 0 6 3 the entire cron string? If so, it's incomplete and probably is why Splunk is not running the report at the right time. Try 0 6 3 * *.

0 6 3 is not a valid cron string. It must have 5 arguments, not just 3.
