Release : 20.3
Component : UIM - XENDESKTOP Probe 4.23
Different Causes and Probe Defect
• Log On Duration - QOS_XENDESKTOP_BROKERSESSION_LOG_ON_DURATION
The reason why it is returning NULL values is a defect in the probe. We are fixing this and this should be available in the next release of the probe we are working on: XenDesktop version 4.24 (Currently beta version, GA Version not available yet as per October 2021)
• Licensing Grace Period Times Remaining - QOS_XENDESKTOP_SITE_CONTROLLER_LICENSING_GRACEPERIOD_TIMES_REMAINING -
The possible reason for getting NULL values for this issue is License Grace period not enabled in the Xendesktop server:
It is expected that the probe will collect 'NULL' values if Licensing Grace period is not enabled (as shown in the above screenshot from the data folder.
• Current Session Count - QOS_XENDESKTOP_MACHINE_CURRENT_SESSION_COUNT and QOS_XENDESKTOP_MACHINE_SESSIONCOUNT
The reason why it is returning NULL values is a defect in the probe. We are fixing this and this should be available in the next release of the probe we are working on: XenDesktop version 4.24 (Currently beta version, GA Version not available yet as per October 2021)

• Network - QOS_XENDESKTOP_LOADINDEX_NETWORK
This available metric in the probe GUI can be disabled/ignored as it refers to an old certification for old XENDESKTOP versions.
On the current cirtrix documentation this metric is not available:
https://developer-docs.citrix.com/projects/citrix-virtual-apps-desktops-sdk/en/1912/
It is expected that the probe collects NULL values if the metric is not provided at the source.
