    Session Timeout

    • Client Heartbeat Interval - Controls the interval between Horizon Client heartbeats and connected state. These heartbeats report to the broker the amount of idle time that has passed. Idle time occurs when no interaction occurs with the end point device, as opposed to idle time in the desktop session. In large desktop deployments, setting the activity heartbeats at longer intervals might reduce network traffic and increase performance.

    • Client Idle User - Maximum time that a user can be idle while connected to the tenant. When this maximum is reached, the user is disconnected from all active Horizon Client Desktop sessions. The user must re-authenticate to re-access the Horizon Client.


      Set the Client Idle User timeout to be at least double the Client Heartbeat Interval to avoid unexpected disconnects from desktops.

    • Client Broker Session - Maximum time that a Horizon Client instance can be connected to the tenant before its authentication expires. The timeout count starts each time you authenticate. When this timeout occurs, you can continue to work. If you perform an action that causes communication to the broker, such as changing settings, the system requires you to re-authenticate and log back in to the desktop.


      The Client Broker Session timeout must be at least equal to the sum of the Client Heartbeat Interval and the Client Idle User timeout.

    • User Portal Timeout - How long you can be on the User Portal when you try to broker a connection before you need to log in again.

    User Portal Configuration

    This feature is deprecated.


    Enable User Session Information - This feature allows user and domain data to be used by the Cloud Monitoring Service (CMS) for reports on the Reports page. If it is disabled, the following are not provided: 

    • The Unique User Summary feature of the Utilization report

    • The Session History report


    The agents on the virtual machines (RDSH and VDI) need outbound Internet access so they can send the data to Horizon Cloud.

    HTML Access

    Cleanup credentials when tab is closed - Controls whether to delete credentials of the broker session when a HTML Access portal connection tab is closed.

    Agent Pairing

    Sets a policy on the tenant which determines the access of legacy (pre-16.6.0) and 16.6.0 agents. Options are as follows:

    • 15.3 Compatibility Mode - Allows legacy and 16.6.0 agents to be paired with Desktop Manager. This is the default setting for upgraded setups.

    • 16.6 Upgrade Mode - Restricts legacy agents, but allows un-bootstrapped 16.6.0 agents on persistent desktops and bootstrapped 16.6.0 agents. This mode does not restrict desktops that are already paired using 15.3.x agents unless the desktop or agent service is restarted.

    • 16.6 Mode - Allows only bootstrapped 16.6.0 agents to be paired. This mode does not restrict desktops that are already paired using 15.3.x agents or un-bootstrapped 16.6.0 agents unless the desktop or DaaS agent service is restarted. This is the default setting for fresh installs.

    When to change this setting:

    • Change from 15.3 Compatibility Mode to 16.6 Upgrade Mode only when there are no longer any pre-16.6 agents in the system BUT there are some dedicated desktops from before the upgrade with their agents upgraded to 16.6.

    • Change from 15.3 Compatibility Mode to 16.6 Mode when there are no longer any pre-16.6 agents or 16.6 agents that are paired with legacy credentials. Once the 16.6 mode is enabled, only VMs creating using bootstrapped images will work.

    RDSH Farm

    Defines policy parameters for RDSH farms.

    • Session Lifetime Reminder Message - This message reminds users that they will be logged off after a specified grace period.

      Default message is "Dear user, your session has reached the maximum lifetime, you will be logged off in {0} minutes". The value specified in the Grace Period field replaces {0} in the message seen by the user.

    • Grace Period - Interval of time after which user is logged off following Session Lifetime Reminder Message.
