Grafana alerts notification

Hello ,
Generally i am creating an cpu alert rule in grafana for proemetheus datasource.
Here i want to get the alert to evaluate for every 24hrs.
Where i have to mention this.For every 24 hrs i want the condition to be checked.

And also is there any solution to disable the alert for if there are no alerts for that particular rule for last 24hrs.
Can anyone clarify.
Thanks in advance
