grafana cannot send recovery message in time

I’m using grafana’s alerting feature.
When an alarm rule triggers an alarm, I receive the alarm information through webhok,
but when the alarm is restored, the time when I receive the recovery information and the time when the [show state history] becomes Normal is delayed a lot

The time when grafana resumes message sending is the same as the time when it becomes Normal in [show state history]

@patrickering Welcome to the Grafana forum.

I also use webhooks in the same manner that you describe, and the Resolved state comes through usually within a few minutes of the alert going from the Firing state to the Normal state. When you say 'is delayed a lot", can you be more specific?
