I think the alarm goes off because Veeam ONE is in constant communication (eg ping) with the VM and when to stop responding the alarm . There are cases that the loss is 1 second and re- connect . I was wondering if you can set the delay. For example , if the machine falls in 10 seconds and it has not returned the connection, if I warn you of this .

In this case I would suggest using trigger after option as a tolerance setting for your alarm. If you set it to 2 or more, then alarm will only be triggered if two events are captured by Veeam ONE server.
