How's the Number of Licensed Objects are Calculated?
ControlUp 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.
Note: Sessions and Servers you see in Help > About > Licensing is not the machines and sessions you see in the Console under the different views.
This is how the License page is displayed:
The exact licensing count will be displayed in the bottom right corner:
(1) Sessions:
- User sessions - sessions running on managed TS/RDS servers (e.g. TS/RDS with the ControlUp agent installed).
- EUC sessions - sessions discovered via the EUC site integration.
- User Sessions running on Managed Non-TS/RDS Servers or Workstations will NOT be counted here.
- If the same user session is discovered from a managed TS/RDS server and a EUC site, the session is merged into a single record and consumes a single license.
(2) Servers:
- Managed Windows Servers such as SQL, IIS or AD servers (e.g. Windows server OS with the ControlUp agent installed)
- TS/RDS servers are NOT counted here (TS/RDS servers do not consume a license, only running user sessions are counted)
- Workstations are NOT counted here
(3) Workstations:
- Managed Windows Client such as Windows 7, Windows 8 or Windows 10 (e.g. Windows client OS with the ControlUp agent installed)
(4) Cloud Instances:
- All running EC2 Instances ('AWS State' column) and as long there is no ControlUp Agent installed.
(5) Agentless Managed VMs:
- Agentless Managed VMs - These are Virtual Machines that are monitored via the hypervisor API with no ControlUp agent running on that VM.
- XenDesktop Brokers - XD brokers discovered via the XenDesktop site integration feature.
(6) NetScaler Appliances:
- NetScaler Monitoring has a different pricing module. Please refer to sales@controlup.com for more information about pricing.
- There are several flavors for the NetScaler product:
- NetScaler MPX - 1 license Unit is needed per device or per HA pair of MPX.
- NetScaler VPX - 1 license Unit is needed per device or per HA pair of VPX
- NetScaler CPX - 1 license Unit is needed per device or per HA pair of CPX
- NetScaler SDX – 0 license Unit is needed for the SDX. Every VPX instance hosted on the SDX requires 1 license Unit per HA pair.
- There are several flavors for the NetScaler product:
For example, if you are monitoring a XenApp farm on which 800 user sessions are currently running and in addition you monitor 300 VDI workstations and 400 VMs as well as 5 Netscaler appliances you will need a total license of 1500 licensed objects (800 + 300 + 400) plus 5 Netscaler appliances licenses. 
Note: From ControlUp v7.1 licensing method was changed. This article refers to v7.1 and above only.
