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:
# Local curl localhost:9200/_nodes/_local # Address curl localhost:9200/_nodes/10.0.0.3,10.0.0.4 curl localhost:9200/_nodes/10.0.0.* # Names curl localhost:9200/_nodes/node_name_goes_here curl localhost:9200/_nodes/node_name_goes_* # Attributes (set something like node.rack: 2 in the config) curl localhost:9200/_nodes/rack:2 curl localhost:9200/_nodes/ra*:2 curl localhost:9200/_nodes/ra*:2*
