Goliath Performance Monitor (GPM) requires Citrix version 7.6 or later with ODATA v3. To check your version of ODATA in use, use the following commands.
The following Citrix document includes the required commands and reference information:
https://docs.citrix.com/en-us/legacy-archive/downloads/xenapp-xendesktop-7-6.pdf
On Page 2850 of the doc, refer to the Get-MonitorServiceInstance command. This command tells what versions of OData are currently supported in the Citrix site implementation for the DDC in question.
To get the OData version
- Open a PowerShell window and run asnp Citrix.*
This command enables the Citrix snap-ins PS module. - Next run get-monitorserviceinstance
- In the output, look for "Citrix/Monitor/OData/v3"
If you only see v1 and or v2 you will need to update Citrix to get the latest OData version installed.
