Not able to send mail alert mail for given threshold

Hi All,

I’m trying to configure alert for my dashboard, but for every time when the threshold is breached it is not giving any mail.

My alert configuration :

My query:
SELECT mean(usage_system) as "system" FROM "cpu" WHERE cpu = 'cpu-total' GROUP BY time(5m),*

After setting up the alert configuration we got the initial mail but after that whenever the threshold is breached we did’t receive any alert mail.

Notifications are only sent when alert rule changes state, not every time it is evaluated. It needs to go back to OK for another notification to be sent

@torkel but in my dashboard alert rule is not being changed i.e (ok --> alert or alert --> ok). even when the threshold is being breached.
