You can use endeca-cmd version, or the version operation of the Manage Web Service, to list the version of the Oracle Endeca Server and the Dgraph processes for each of the enabled data domains.
The version command returns information about the Endeca Server software version, and the version of the Dgraph nodes in each of the enabled data domains hosted by this Endeca Server cluster.
To request a version:
endeca-cmd version
<ns1:version xmlns:ns1="http://www.endeca.com/endeca-server/manage/1/0"/>
