Introduction

MarkLogic Server has a notion of groups, which are sets of similarly configured hosts within a cluster.

Application servers (and their respective ports) are scoped to their parent group.

Therefore, you need to make sure that the host and its exposed port to which you're trying to connect both exist in the group where the appropriate application server is defined. For example, if you attempt to connect to a host defined in a group made up of d-nodes, you'll only see application servers and ports defined in the d-nodes group. If the application server you actually want is in a different group (say, e-nodes), you'll get a connection error, instead.

Questions

Can I use any xdmp builtins to show which application servers are linked to particular groups?

The code example below should help with this:
