Grafana Alerts - Not getting more that 1 alerts if the problem persists

I configured an alert through Grafana and I left the CPU in the server in a given status intentionally (CPU AVG > 1.1) in order to activate the alert.
Although the alert arrived to my TEAMS channel , it happened only once. Shouldn’t normally continue to receive alerts in my TEAMS channel since the problem exists approximately over 20 minutes ?

Grafana sends the alert only once regardless if the problem persists ?
Does anyone has an idea?

Hello :wave: and welcome to the forum, @geogour

Alerting questions are difficult to answer without all the details regarding your grafana version, whether you are using legacy alerting or unified alerting, and if you had any old alerting rules that have been migrated to the new unified alerting platform
