Measures reported by CtxXcXDCSessionTest

In the event of a session overload on XenDesktop, administrators may want to know the type of sessions that may have contributed to the overload - HDX sessions? or RDP sessions? This can be determined using the CtxXcXDCSessionTest test. For every type of session (HDX and RDP) on the broker, this test reports the total session count and the status of the sessions.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Total_sessions Indicates the total number of user sessions. Number This is a good indicator of the session load on the broker. If a consistent increase is observed in the value of this measure for the All descriptor, it could hint at a potential overload condition. In such situations, you can compare the value of this measure across session types to figure out which type of session is high on the broker - HDX or RDP?
Active_sessions Indicates the number of user sessions of this type that are currently active on the broker. Number A consistent zero value could indicate a connection issue.

To determine the details of the currently active sessions, use the detailed diagnosis of this measure.

Connected_sessions Indicates the number of sessions of this type that are currently connected. Number The detailed diagnosis of this measure if enabled, lists the Session ID, the name of the machine, the name of the catalog and delivery group to which the machine belongs, the zone to which the catalog belongs, the server on which the machine is hosted, the hypervisor name, the user who is active on the session, the protocol used for connecting to the session, the Client IP and version, the state of the session, the time for which the session is connected, the time at which the state of the session changed, the start time of the session, the brokering time, the number of session supported - whether single session or multiple session, the applications that are currently in use if the machine in operation is a XenApp etc.
Disconnected_sessions Indicates the number of sessions of this type that are currently disconnected Number If all the current sessions suddenly log out, it indicates a problem condition that requires investigation. The detailed diagnosis of this measure lists the sessions that were logged out.
Reconnecting_sessions Indicates the number of sessions of this type that are reconnecting soon after a disconnect. Number  
Preparing_sessions Indicates the number of sessions of this type that are currently in the Preparing state. Number  
Non_brokered_sessions Indicates the number of user sessions of this type that were not brokered by the machines managed by this broker. Number  
Unknown_sessions Indicates the number of sessions of this type that are currently in Unknown state. Number  
Other_sessions Indicates the number of sessions of this type that are currently in Other state. Number  
Hidden_sessions Indicates the number of sessions of this type that are currently hidden. Number  
Auto_brokered_sessions Indicates the number of sessions of this type that are brokered without the use of this broker. Number  
App_prelogon Indicates the number of applications that are in pre-logon state for the sessions of this type. Number This measure is only applicable for Server OS Machines descriptor.
App_prelaunched Indicates the number of applications that are prelaunched for the sessions of this type. Number This measure is only applicable for Server OS Machines descriptor. The session prelaunch enables all or specified users access applications quickly, by starting sessions before they are requested. The session will wait for a user, and when the user starts an application prelaunched session is replaced with a regular session.
App_active Indicates the number of applications that are currently running in the sessions of this type. Number This measure is only applicable for Server OS Machines descriptor. The value of this measure should be high.
App_lingering Indicates the number of sessions of this type that are in active state even after the applications are closed. Number This measure is only applicable for Server OS Machines descriptor.
App_noapps Indicates the number of sessions of this type that are active without any application launch. Number This measure is only applicable for Server OS Machines descriptor.
