Most cluster level APIs allow to specify which nodes to execute on (for
|
|
|
|
|
example, getting the node stats for a node). Nodes can be identified in
|
|
|
|
|
the APIs either using their internal node id, the node name, address,
|
|
|
|
|
custom attributes, or just the `_local` node receiving the request. For
|
|
|
|
|
example, here are some sample executions of nodes info:
