The Metadata Manager Agent is a program that Metadata Manager uses to access metadata sources and extract source metadata. By default, the Metadata Manager Agent runs on the nodes where the Metadata Manager Service runs. To extract metadata from Tableau, you can use the Metadata Manager Agent that is installed on any Windows machine.
You must install the Metadata Manager Agent separately on a Windows machine when the domain uses Kerberos authentication or when the Metadata Manager Service runs on UNIX.
