How alert once a week

Hi, i’m setting a grafana instance with mysql as data source, i have a graph panel and i want to set alerts for each query. data is uploaded every friday so, in the other days, data not changes.
i want to set alert rule for evaluate only on fridays and send emails. i tried to set it but i received emails every hour with the “not data” alert. i dont know how to set it right.


This is more a feature request, please check :

There is also a workaround there using module :smile:

Hope it helps.

Good Luck
