This patch adds a /v1/coordinate/node/:node endpoint to get the network coordinates for a single node in the network. Since Consul Enterprise supports network segments it is still possible to receive mutiple entries for a single node - one per segment.

Coordinate HTTP Endpoint
The /coordinate
endpoints query for the network coordinates for nodes in the
local datacenter as well as Consul servers in the local datacenter and remote
datacenters.
Please see the Network Coordinates internals guide for more information on how these coordinates are computed, and for details on how to perform calculations with them.
Read WAN Coordinates
This endpoint returns the WAN network coordinates for all Consul servers, organized by datacenters. It serves data out of the server's local Serf data, so its results may vary as requests are handled by different servers in the cluster.
Method | Path | Produces |

Sample Request
$ curl \
https://consul.rocks/v1/coordinate/datacenters
Sample Response
[
{
"Datacenter": "dc1",
"AreaID": "WAN",
"Coordinates": [
{
"Node": "agent-one",
"Coord": {
"Adjustment": 0,
"Error": 1.5,
"Height": 0,
"Vec": [0, 0, 0, 0, 0, 0, 0, 0]
}
}
]
}
]
In Consul Enterprise, this will include coordinates for user-added network
areas as well, as indicated by the AreaID
. Coordinates are only compatible
within the same area.
Read LAN Coordinates for all nodes
This endpoint returns the LAN network coordinates for all nodes in a given datacenter.
Method | Path | Produces |
---|---|---|
GET |
/coordinate/nodes |
application/json |
The table below shows this endpoint's support for blocking queries, consistency modes, and required ACLs.
Blocking Queries | Consistency Modes | ACL Required |
---|---|---|
YES |
all |
node:read |
Parameters
dc
(string: "")
- Specifies the datacenter to query. This will default to the datacenter of the agent being queried. This is specified as part of the URL as a query parameter.
Sample Request
$ curl \
https://consul.rocks/v1/coordinate/nodes
Sample Response
[
{
"Node": "agent-one",
"Segment": "",
"Coord": {
"Adjustment": 0,
"Error": 1.5,
"Height": 0,
"Vec": [0, 0, 0, 0, 0, 0, 0, 0]
}
}
]
In Consul Enterprise, this may include multiple coordinates for the same node,
each marked with a different Segment
. Coordinates are only compatible within the same
segment.
