Nodes API 

We can also manage nodes using the API.

Authentication

Important: All these methods are authenticated. 

OperationMethodURLResponseExample
AuthenticatePOSThttp://host/en/omk/admin/login

http://uburnto.opmantek.net/en/omk/admin/login


{"username": "username",
"password": "password"}


We should receive a 200 response and a cookie, that we can reuse for next API calls. 

Create a remote Node

If we want to create a node in a remote cluster, we should indicate the remote cluster id in configuration.pollers: cluster_id

cluster_id is the uuid of which opHA server the node belongs to.

E.x.

Create RemotePOSThttp://host/en/omk/admin/api/v2/nodes.jsonIt will return the json node, the same structure that the CREATE. 

http://uburnto.opmantek.net/en/omk/admin/api/v2/nodes.json

It will return the same output as for a local node:

    "activated": {
        "NMIS": 1,
        "opConfig": "0",
        "opEvents": "1"

Remote Nodes Error

If any operation has a remote cluster id, the API will try to edit in the remote server. If this operation is not possible, it will fail. 

In order to succeed: 

If we should want to edit the remote node locally for some reason, we should use node_admin cli tool.
