Manually delete thousands of Hypervisor alerts? No way. Script a removal? Heck yeah!
In massive vmware environments you sometimes will get flooded ESXi alerts into Citrix Director if the backend systems are in migration, updates, or general maintenances. However there is no process to clear these errors in bulk from the Citrix Director console. To address this Citrix does have a script to clear those.

Login to your Delivery Controller and run this PowerShell script to clear all entities. If you use a dedicated service account for access to the CVAD databases, make sure to run this PowerShell session as that user.
