Cluster management APIs #

Operator-facing /_cluster/* endpoints beyond health and state: the allocation dashboard, node removal, and join-token management.

Regions #

GET /_cluster/_regions

A lightweight summary of every region this node knows about — identity (name, uuid, zone), leader, member nodes with their API/RPC addresses, and per-region counts. The region serving the request is marked local, telling you which /_cluster/_region/_local/... endpoints apply to it.

Allocation dashboard #

GET /_cluster/allocation

The leader’s shard-allocation view: the effective cluster.routing.* settings, per-node shard load, the recent allocation/relocation task history (newest first) and how many tasks are in flight. Answers “what is the allocator doing right now”.
