eG Monitoring
 

Measures reported by CtxCdUserTest

The Logon Performance test monitors the user logon process from a delivery group perspective; in other words, it monitors user logins to the desktops/applications in a delivery group, measures the ‘aggregate’ duration of the login across all users to that group, and thus points to bottlenecks in the user logon process to that group.

The CtxCdUserTest on the other hand, provides the user-perspective to logon monitoring. In other words, this test tracks each user who logs into a desktop or accesses an application via the controller, reports in real-time the logon experience of that user, and pinpoints where exactly that user's logon slowed down. When a user complaints of delays in accessing his/her virtual desktop, this test will lead administrators straight to what is causing the delay. Detailed diagnositics provided by this test reveal which machines/applications a user is accessing and which delivery group these machines/applications belong to.

Outputs of the test :One set of results for each user to the controller in the site

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
No_of_logins Indicates the number of times this user has logged in since the last measurement period Number  
Avg_logon Indicates the average time taken for this user to login to desktops/access applications. Seconds If this measure reports a high value consistently, it could indicate a slowdown in the logon process.

Compare the value of this measure across users to know which user's logon is taking the longest.
Brokering Indicates time taken by this user to complete the process of brokering sessions. Seconds A high value indicates that brokering is taking a long time.

If the Average logon duration is very high, you may want to compare the value of this measure with that of the Time taken for starting VM, HDX connection duration, Authentication time, GPOs duration, Logon scripts duration, Profile load time, and Interactive session duration 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 by the controller to start the machines accessed by this user. Seconds A high value indicates that machines are taking too long to startup.

If the Average logon duration is very high, you may want to compare the value of this measure with that of the Brokering duration, HDX connection duration, Authentication time, GPOs duration, Logon scripts duration, Profile load time, and Interactive session duration 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 by the controller to complete the steps required for setting up the HDX connection from this user to the machines accessed by the user. Seconds A high value indicates that HDX connections are taking time to be established.

If the Average logon duration is very high, you may want to compare the value of this measure with that of the Brokering duration, Time taken for starting VM, Authentication time, GPOs duration, Logon scripts duration, Profile load time, and Interactive session duration 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 taken by the controller to authenticate this user's sessions. Seconds A high value indicates authentication delays.

If the Average logon duration is very high, you may want to compare the value of this measure with that of the Brokering duration, Time taken for starting VM, HDX connection duration, GPOs duration, Logon scripts duration, Profile load time, and Interactive session duration 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 accessed by this user. Seconds A high value indicates that GPO application is taking time.

If the Average logon duration is very high, you may want to compare the value of this measure with that of the Brokering duration, Time taken for starting VM, HDX connection duration, Authentication time, Logon scripts duration, Profile load time, and Interactive session duration 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 accessed by this user. Seconds A high value indicates that logon script execution is taking time.

If the Average logon duration is very high, you may want to compare the value of this measure with that of the Brokering duration, Time taken for starting VM, HDX connection duration, Authentication time, GPOs duration, Profile load time, and Interactive session duration 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 this user. Seconds A high value indicates that profiles are taking too long to load.

If the Average logon duration is very high, you may want to compare the value of this measure with that of the Brokering duration, Time taken for starting VM, HDX connection duration, Authentication time, GPOs duration, Logon scripts duration, and Interactive session duration 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 this user. Seconds A high value indicates delays in handing off keyboard and mouse control to users.

If the Average logon duration is very high, you may want to compare the value of this measure with that of the Brokering duration, Time taken for starting VM, HDX connection duration, Authentication time, GPOs duration, Logon scripts duration, and Profile load time 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?
Pre_user_init Indicates the time overlaps with Group Policy Objects and logon scripts (configured through GPO). Seconds If the value of this measure is high, administrators should consider optimizing the Group Policy Objects and logon scripts configured through GPO.
User_init Indicates the time taken for executing userinit.exe for this user. Seconds When a user logs on to a Windows machine, Winlogon runs userinit.exe which runs logon scripts, re-establishes network connections, and then starts Explorer.exe, and the Windows user interface.

If Average logon duration is abnormally high, then compare the value of this measure with the other time measurements to determine whether/not the logon delay can be attributed to slowness in the completion of user initialization tasks.

A high value of this measure could indicate that the machine is not able to reach domain controller a network issue or a large number of logon scripts (corrupt) are configured through active directory user object. To resolve the issue, the administrators should immediately initiate the investigation before it causes serious impact on the logon process.
Shell_duration Indicates the duration between the initialization of the user interface to the time the user receives keyboard and mouse control. Seconds A high value of this measure could indicate that the VDA is heavily loaded with numerous applications running or if desktop has too many icons, etc.
Delay_duration Indicates the cumulative time delay between the Pre--userinit and Userinit phases. Seconds  
Other_duration Indicates the time taken by this user to perform processes other than logon related processes. Seconds
