Citrix Site environment missing in Group Members (VMs) of Overview Applications dashboard because of Citrix Awareness discovery issue
Issue / Symptom
The Citrix Site group displayed in Overview Applications dashboard doesn’t contain any Citrix Delivery Controller, Citrix Desktop OS Machine or Citrix Server OS Machine; only VMs with Citrix StoreFront role are shown inside Group Members (VMs) datagrid.
Environment on which this was spotted was SCOM 2012/2016 hosted on Windows Server 2016.
The root cause of the problem was the Windows Management Framework 5.1 (build 5.1.14393) that has a problem with the following PS cmdlet:
Test-Connection <IP> -Quiet
There was no response – the command never completed. As a result of that discovery failed.
Solution / Advice
Check PowerShell version ($PSVersionTable.PSVersion) and run Windows update to install all Windows Cumulative updates containing also update for Windows Management Framework 5.1.
The issue is fixed within WMF 5.1.14394.
