[AKG11]

Hi,

I am looking to setup an alert which support to be run every weekday at 7:30PM. Search window for alert query should be from 7PM previous day to 7PM current day.
How can I setup this alert.

Thanks

Retracted. @richgalloway 's solution will work.

To run the alert at 7:30pm, use a cron schedule of 30 19 * * *.

To set the search window, use earliest=-1d@d+19h latest=@d+19h
