Zerto Alarms In VMware vSphere : Alarms and Alerts
  
Alarms and Alerts
Zerto is configured with a set of predefined alarms that monitor the software, including problems with resources such as journals, recovery storage, and connectivity between Zerto. When an ongoing problem is identified by Zerto, an alert is issued. This alert also results in the appropriate Zerto alarm being triggered in the vCenter Server. The same vCenter Server alarm can be triggered by more than one Zerto alert.
Note: Disabling an alarm in vCenter Server will not stop the Zerto alert being fired.
Any Zerto alarm will only be turned off when all instances of the alert are turned off. For example, if you pause two VPGs, a vCenter Server alarm is raised. If you resume just a single VPG the alarm remains on. Only when no VPGs are paused is the alarm stopped.
