Black Hole Machines Alert

Citrix Analytics for Performance scans for black hole machines every 15 minutes and sends out an alert to enable administrators to proactively mitigate session failures faced by users due to black hole machines. Machines that have failed to service four or more consecutive session requests are termed Black hole machines. With black hole failure alerting, administrators need not be logged into Performance Analytics to know the session failures that occurred due to black hole machines. Details of the machines and the session failures caused by them are sent in the alert emails to administrators. The Black Hole Machines alert policy must be enabled to receive these emails.
