Cause

Different Causes and Probe Defect

Environment

Release : 20.3

Component : UIM - XENDESKTOP Probe 4.23

Resolution

•   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)

 

 

QOS_XENDESKTOP_MACHINE_CURRENT_SESSION_COUNT is the metric for VDA.

QOS_XENDESKTOP_MACHINE_SESSIONCOUNT. : s the output of Get-BrokerMachine command for the physical or virtual machine, which has been configured in the site.
SessionCount (System.Int32) Count of number of sessions on the machine.

•   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.
