Avg. User Logon Duration

Summary

Monitors the average logon duration for a delivery group. The logon duration is the elapsed time from the point when a user launches a desktop or application via Storefront to the point when a user can start using it.

Configuration

Overridable parameters:

Causes

There are various reasons for a slower user logon including:

• A new application was installed.

• An operating system update occurred.

• Configuration changes were made.

Also, check root causes of all logon phases which are included into the complete logon duration.

Additional

User logon is a complex and a resource intensive process on a Citrix server or desktop OS machine. It is initiated when Citrix delivery group load balancing algorithm selects the system where published application and/or desktop that user has selected will be started, and ends when the application and/or desktop is running and the user is able to interact with it.

Management Pack breaks down the Citrix XenApp/XenDesktop logon process into the following phases.

Phase 1: Brokering

The time taken to decide which desktop to assign to the user.

Phase 2: VM start

In case the session required a machine to be started, the time taken to boot the desktop.

Phase 3: HDX connection

The time taken to complete the steps required in setting up the HDX connection from the client to the VM, depending on the network.

Phase 4: Authentication

The time taken to complete authentication to the remote session.

Phase 5: Profile load

The phase starts just after the user credentials are validated and lasts until the profile is downloaded from the profile storage (network share).

Phase 6: GPOs

During this phase, group policy objects are applied/defined on the Domain Controller.

Phase 7: Logon scripts

This phase covers the time taken for the logon scripts to be executed.

Phase 8: Interactive session

The phase starts in parallel with GPOs phase and covers Citrix specific activity before it launches the requested application: launching seamless windows engine shell, auto creation of client printers and ICA client update process.
