Number of Hypervisors OK / (Number of Hypervisors Failed + Number of Hypervisors OK X 100)
#### License Server Connectivity
Additionally, the license server connection (LicenseServerAvailability) is assessed in the **CVAD License Server** metric. If the license server is disconnected, one point is deducted from the total.
#### Example
**CVAD Broker Health** is calculated using the 13 parameters above (11 service states + hypervisor status + license server connectivity). If any of these services or connections return a status of `DisabledByRegistry`, one point is deducted from the total.
The final health score is calculated as:
**(FieldsOK/13) X 100**
For example, if 8 out of the 13 monitored services are running normally, then broker health is calculated as:
**(8/13) X 100** = **61.5%**
## **Known issues**
In some cases, you might experience decreased Citrix performance and high memory consumption on the **citrix.monitor.exe** process due to extra calls from our Data Collector.
To fix this issue:
1. Go to `C:\Program Files\Citrix\Monitor\Service` and open **Citrix.Monitor.exe.config**.
2. Add the following line to change the default page size for the OData V4 endpoint: `add key="ODataV4ResponsePageSize" value="1000"`

3. Restart the Citrix Monitor service.
