How AlertManager webhook notification retry works in case the receiver is donw for 1 hour ?

[Abdul]

Hi All,

I have queries regards, AlertManager webhook notification in scenarios like receiver is down between 5 minutes to 60 minutes. Will AlertManager sends alerts occurred in between this time once receiver is up ?. 

For example,

AlertManager Wehhook is configured at 10.00 AM and Alerts are flowing then receiver is DOWN between 10:30 AM to 11:30 AM. Now created alerts in between 10.30 AM to 11.30 AM, will all alerts sends to receiver once receiver is UP ?. or Alerts won't be sent ?.

Thanks,

Abdul
