When the alarm is restored, the unrecovered alarms will be issued together

[ktpktr0]

What did you do? I use dingtalk as the alarm receiver, and when the alarm is restored, it will send out the unrecovered alarms together, even if these alarms do not reach the alarm interval

What did you expect to see?

Alarm recovery issued separately. When I use version 0.22, it seems to be working properly

What did you see instead? Under which circumstances?
