Measures reported by CtxXcXDLogonTest

The process of a user logging into a desktop/server OS machine managed by a XenDesktop Broker is complex. First, the user's login credentials are authenticated. Then, the corresponding user profile is identified and loaded. Next, group policies are applied and logon scripts are processed to setup the user environment. Then, a HDX connection is established with the VM, subsequent to which, the VM starts and hands off keyboard and mouse control to the user. In the meantime, additional processing may take place for a user – say, applying system profiles, creating new printers for the user, and so on. A slowdown in any of these steps can significantly delay the logon process for a user and may adversely impact the logins for other users who may be trying to access desktops/applications at the same time. Hence, if a user complains that he/she is unable to access an application/desktop, administrators must be able to rapidly isolate exactly where the logon process is stalling and for which user.

The CtxXcXDLogonTest test tracks user connections to each delivery group, measures the average time taken for users to access desktops/applications delivered by each group, isolates the group to which user logins are slow, and accurately pinpoints where the login process is bottlenecked. Detailed diagnostics provided by this test point to the precise user who is experiencing the slowness.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Avg_logon Indicates the average time taken for users to login to desktops/applications offered by this delivery group. Secs If this measure reports a high value consistently, it could indicate a slowdown in the logon process.

You can use the detailed diagnosis of this measure to understand the logon experience of each user to the delivery group, identify that user who took the maximum time to login, and accurately isolate where he/she experienced slowness.

No_of_logins Indicates the number of users who recently logged into desktops/applications delivered by this delivery group. Number This is a good indicator of the current user load on a delivery group.
Brokering Indicates time taken to complete the process of brokering sessions to this deliver group. Secs A high value indicates that brokering is taking a long time.

If the Avg_logon is very high, you may want to compare the value of this measure with that of the Vm_start, Hdx, Authentication, Gpos, Logon_scripts, Profile_load, and Interactive_session measures to know where exactly the user logon process slowed down – is it during authentication? Is it during brokering? Is it when establishing the HDX connection? Is it when applying GPOs? Is it during logon scripts execution? Is it while loading user profiles? Is it when starting the VM? Or is it when handing over control to the user?

Vm_start Indicates the time taken for starting the machines in this delivery group. Secs A high value indicates that machines are taking too long to startup.

If the Avg_logon is very high, you may want to compare the value of this measure with that of the Brokering, Hdx, Authentication, Gpos, Logon_scripts, Profile_load, and Interactive_session measures to know where exactly the user logon process slowed down – is it during authentication? Is it during brokering? Is it when establishing the HDX connection? Is it when applying GPOs? Is it during logon scripts execution? Is it while loading user profiles? Is it when starting the VM? Or is it when handing over control to the user?

Hdx Indicates the time taken to complete the steps required for setting up the HDX connection from the client to the machines in this delivery group. Secs A high value indicates that HDX connections are taking time to be established.

If the Avg_logon is very high, you may want to compare the value of this measure with that of the Brokering, Vm_start, Authentication, Gpos, Logon_scripts, Profile_load, and Interactive_session measures to know where exactly the user logon process slowed down – is it during authentication? Is it during brokering? Is it when establishing the HDX connection? Is it when applying GPOs? Is it during logon scripts execution? Is it while loading user profiles? Is it when starting the VM? Or is it when handing over control to the user?
Authentication Indicates the time time taken to authenticate remoe sessions to the machines in this delivery group. Secs A high value indicates authentication delays.

If the Avg_logon is very high, you may want to compare the value of this measure with that of the Brokering, Vm_start, Hdx, Gpos, Logon_scripts, Profile_load, and Interactive_session measures to know where exactly the user logon process slowed down – is it during authentication? Is it during brokering? Is it when establishing the HDX connection? Is it when applying GPOs? Is it during logon scripts execution? Is it while loading user profiles? Is it when starting the VM? Or is it when handing over control to the user?
Gpos Indicates the time taken to apply group policy settings on the machines in this delivery group. Secs A high value indicates that GPO application is taking time.

If the Avg_logon is very high, you may want to compare the value of this measure with that of the Brokering, Vm_start, Authentication, Hdx, Logon_scripts, Profile_load, and Interactive_session measures to know where exactly the user logon process slowed down – is it during authentication? Is it during brokering? Is it when establishing the HDX connection? Is it when applying GPOs? Is it during logon scripts execution? Is it while loading user profiles? Is it when starting the VM? Or is it when handing over control to the user?
Logon_scripts Indicates the time taken for logon scripts to be executed on the machines in this delivery group. Secs A high value indicates that logon script execution is taking time.

If the Avg_logon is very high, you may want to compare the value of this measure with that of the Brokering, Vm_start, Authentication, Hdx, Gpos, Profile_load, and Interactive_session measures to know where exactly the user logon process slowed down – is it during authentication? Is it during brokering? Is it when establishing the HDX connection? Is it when applying GPOs? Is it during logon scripts execution? Is it while loading user profiles? Is it when starting the VM? Or is it when handing over control to the user?

Profile_load Indicates the time taken by the logon process to load the profile of the users to this delivery group. Secs A high value indicates that profiles are taking too long to load.

If the Avg_logon is very high, you may want to compare the value of this measure with that of the Brokering, Vm_start, Authentication, Hdx, Gpos, Logon_scripts, and Interactive_session measures to know where exactly the user logon process slowed down – is it during authentication? Is it during brokering? Is it when establishing the HDX connection? Is it when applying GPOs? Is it during logon scripts execution? Is it while loading user profiles? Is it when starting the VM? Or is it when handing over control to the user?
Interactive_session Indicates the time taken by the logon process to handoff keyboard and mouse control to the users to this delivery group. Secs A high value indicates delays in handing off keyboard and mouse control to users.

If the Avg_logon is very high, you may want to compare the value of this measure with that of the Brokering, Vm_start, Authentication, Hdx, Gpos, Logon_scripts, and Profile_load measures to know where exactly the user logon process slowed down – is it during authentication? Is it during brokering? Is it when establishing the HDX connection? Is it when applying GPOs? Is it during logon scripts execution? Is it while loading user profiles? Is it when starting the VM? Or is it when handing over control to the user?
