Unix machines cannot show network links and processes. Linux and Windows versions of Netstat are supported, so Linux and Windows machines will show network links and processes.
PowerShell 2.0 or later must be available on each server you wish to trigger discovery on. Note that servers will still appear in a VADA diagram if they do not have PowerShell installed, but you will not be able to discover further connections or associate traffic with the processes on the server. PowerShell 2.0 is installed as standard on Windows Server 2008 R2 and later, and is available for installation on earlier systems via the Windows Management Framework.
