# Veeam VMware: VASA Provider disconnected Alarm

This monitor tracks the vCenter Alarm 'VASA provider disconnected'.

By default, the alarm is triggered by the following events:

- **com.vmware.vc.sms.VasaProviderConnectedEvent**: VASA Provider is connected to the vCenter Server.
- **com.vmware.vc.sms.VasaProviderDisconnectedEvent**: VASA Provider is disconnected from the vCenter Server.

Check that VASA Provider endpoint is accessible from the vCenter Server. For instructions on managing VASA Provider connection settings, see [VMware Docs](https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.storage.doc/GUID-6C8EE052-0504-4BCA-874A-7AB836361AD4.html). If VASA Provider endpoint is inaccessible from the vCenter Server, check the certificate used by the Storage Monitoring Server within the VMware VirtualCenter Management Webservices component; for more information, see this [VMware KB article](https://knowledge.broadcom.com/external/article/335938/registering-a-vasa-provider-with-vcenter.html).
