In some cases, it may be necessary to suppress alarms that occur under specific conditions or during a specific time interval. For example, alarms informing about high resource utilization may need to be suppressed if these alarms occur during a scheduled resource consuming operation (such as backup performed with Veeam Backup & Replication or other operations).
For suppressed alarms, Veeam ONE Monitor does not show any notifications in the console and does not perform any response actions, such as sending email notifications. If, by the end of suppression period, the object stays affected, Veeam ONE Monitor will trigger the alarm with the corresponding severity and will perform the alarm response actions.
On the Suppress tab of the Alarm settings window, specify alarm suppression settings:
- If the alarm must be triggered under any conditions, leave the Do not suppress alarm check box selected.
- To suppress the alarm when a specific resource-consuming operation is performed, select the Suppress when certain task is performed option and choose the necessary types of tasks.

- Veeam Backup activity — suppresses the alarm during Veeam backup and replication jobs. Veeam ONE Monitor automatically detects the beginning and the ending of each job.
For example, if you select Veeam Backup activity check box for the VM CPU Usage alarm, this alarm will be suppressed for all VMs that are backed up or replicated until Veeam Backup & Replication finishes performing the job(s).
- If you select the Veeam Backup activity check box for the Host CPU Usage alarm, this alarm will be suppressed for the entire host where at least one VM is backed up or replicated until Veeam Backup & Replication finishes performing the job(s).
- Snapshot creation — suppresses the alarm during snapshot creation for the object itself or its parent objects.
For example, if you create an alarm for a VM, the alarm will be suppressed for a VM while a snapshot is being created. If you create an alarm for a host, the alarm will be suppressed for the host while a snapshot is being created for any VM on this host.
- Snapshot deletion — suppresses the alarm during snapshot deletion for the object itself or its parent objects.
For example, if you create an alarm for a VM, the alarm will be suppressed for a VM while a snapshot is being deleted. If you create an alarm for a host, the alarm will be suppressed for the host while a snapshot is being deleted for any VM on this host.
- To suppress the alarm according to a specific schedule during the week, select the Suppress alarm based on schedule option. Specify time intervals on specific weekdays during which the alarm must be suppressed.
You can add more than one record for one weekday. Note that the time intervals specified for the same day must not intersect.
