The endpoint id is just a unique identifier for the agent generated when
the agent installs. It is used so that each agent is unique and could
change location and still be the same agent. The host name is just what
the server uses to connect to the agent. The communication is
bi-directional. The agent is sending pings to the server and that is
what determines the online status. When the server needs to do anything
like run a job or retrieve the agent variables on the variables tab, it
uses the host to try to talk to the agent.
