How do we calculate ControlUp Real-Time VDI licenses?

Prev Next

ControlUp for VDI can monitor and manage a wide variety of resources/objects in the virtual and/or physical datacenters.

ControlUp continuously counts the total number of objects that are currently being monitored and requires a number of licenses that adequately cover the size of the environment.

Concurrent Licenses

Concurrent licenses are counted as number of daily managed single user workstations + peak number of concurrent RDS/multi-user sessions.

When using concurrent licensing billed through the daily usage feed, the peak RDS/multi-user sessions metric measures the highest concurrent session count observed during a single calendar day.

  • Daily Evaluation: Captures the maximum volume of simultaneous sessions reached at any point during that 24-hour calendar window.

  • Calculation Formula: ControlUp determines your total usage for the day using the following logic:

    Maximum Daily Usage = Workstations + Daily Session Peak

  • Reporting: This consolidated number (reflecting the previous calendar day's peak) is compiled and reported to the system the following day.

Named User Licenses

  • Named user licenses are counted for both Microsoft RDSH/VDI machines and non-RDSH/VDI machines.

  • Real-Time DX license based on the maximum of either:

    • ControlUp Real-Time DX historical data (number of workstations + sessions running server machines).

    • Unmanaged Citrix/Horizon sessions.

  • If you use the same username/user account in both the Azure VM and Citrix VM, we count this as a single named user.

  • Agentless unmanaged VMs are NOT counted here.

  • Agentless Cloud instances are NOT counted here.

  • General-purpose servers are NOT counted here.

To check your current named user count for licensing, open the web interface, go to Reports > Session Activity, and see the number shown in the Unique Users widget.
