A goal of Citrix is to deliver new features and product updates to customers as and when they are available. New releases provide more value, so there’s no reason to delay updates.
To you, the customer, this process is transparent. Initial updates are applied to Citrix internal sites only, and are then applied to customer environments gradually. Delivering updates incrementally helps to ensure product quality and to maximize the availability.
New features introduced in Citrix Analytics for Performance provide further insights into performance parameters affecting the user experience on Citrix Virtual Apps and Desktops on-premises sites and Citrix DaaS (formerly Citrix Virtual Apps and Desktops service) sites on cloud.

Anomalous Latency Alerts
Poor in-session responsiveness is the primary cause for poor session experience. The Anomalous Latency Alerts feature alerts administrators when there is a significant deviation in the session latency values. The proactive alerting helps administrators identify specific locations or Delivery Groups from which poor sessions might be originating.
A machine learning model is used to determine the baseline latency value for all Delivery Group-Location pairs for a specific customer. The baseline latency value is calibrated every day based on the ICARTT values from the last three days. Any outlier measurements of ICARTT are ignored. If the measured ICARTT has a deviation of 60% or more from the baseline latency value, an alert is generated.
For more information, see the Alerts article.

Zombie Insights and Alerts
The Zombie Sessions sub-pane shows information on session failures that have occurred due to zombie sessions in the environment. A zombie session is an abandoned session on a single-session OS machine resulting in new session launches on the machine to fail. Attempts to launch sessions on this machine fails with an Unavailable Capacity error until the abandoned session is terminated. Zombie Sessions insights aim to help spot these machines with abandoned sessions, thus enabling proactive mitigation of these failures.
A Zombie session alert mail is generated when a new machine with zombie session is detected in the environment in a 15 mins interval. Alert mails are sent to full administrators who have enabled email notifications in Citrix Cloud. Re-alerting on the same machine is done only if the same abandoned session persists on the same machine for over 24 hours from the initial detection.
Clicking View machines displays the Self-service view filtered with the list of machines containing Zombie Sessions. Here, Failure Count represents the number of session failures that have occurred in the selected interval. The Last Failure Type and Reason help root cause reasons for machines containing zombie sessions.
You can disable the Machines with Zombie Sessions alert from the Alert Policies tab.
For more information, see Zombie sessions.

Failure Insights - Black hole machines
Failure Insights in Citrix Analytics for Performance provides insights into session failures that occurred during the chosen time period. This feature is important in helping troubleshoot and resolve session failures faster. It eases the task of admins who need to troubleshoot session failures to improve session availability and hence, the user experience. In this release, Citrix Analytics for Performance provides insights into Black hole machines as a part of Failure Insights.
Some machines in your environment, though registered and appearing healthy might not service sessions brokered to the them, resulting in failures. Machines that have failed to service four or more consecutive session requests are termed as Black hole machines. The reasons for these failures are related to various factors that might affect the machine, such as, insufficient RDS licenses, intermittent networking issues, or instantaneous load on the machine.
The Black hole machines section of Failure Insights shows the number of black hole machines identified in your environment during the selected time period. The presence of black hole machines in the environment impacts session availability. Suggestions to reduce the number of black hole machines in your environment are provided. Clicking the number of black hole machines opens the Machines based self-service view that is filtered to show the black hole machines in your environment during the selected time period. For more information, see Black hole machines.
