Nodes API 

We can also manage nodes using the API.

Important: All this methods are authenticated. 

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

Code Block

"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. 

E.x.

Create RemotePOSThttp://host/en/omk/admin/api/v2/nodes.json

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


Code Block
{"configuration":{"pollers": "a515c63a-0d11-4bcb-a402-39a4600aebb9", "netType":"default","polling_policy":"default","port":"161","collect":1,"threshold":1,"roleType":"default","ping":1,"group":"NMIS9","host":"asgard.opmantek.net","location":null,"customer":null,"businessService":null,"notes":"","host_backup":"","active":null,"community":"","wmiusername":"","wmipassword":"","username":"","context":"","authpassword":"","authkey":"","authprotocol":null,"privpassword":"","privkey":"","privprotocol":null,"serviceStatus":null,"nettype":null,"roletype":null,"node_context_name":"","node_context_url":"","remote_connection_name":"","remote_connection_url":""},"activated":{"opEvents":"1","opConfig":"0","NMIS":"1"},"uuid":null,"current_user_privileges":{"update":true,"delete":true},"name":"test","friendly_addresses":"","friendly_aliases":""}


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

Code Block

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

}

Update a remote Node

If we want to create a node in a remote cluster, we just need to indicate the remote cluster id in cluster_id:

E.x.

Create RemotePUThttp://host/en/omk/admin/api/v2/nodes/node_uuid.json

http://volla.opmantek.net:6042/en/omk/admin/api/v2/nodes/6ce5fd5c-d703-4d03-b36c-b8e01439a9f2.json


Code Block
{"cluster_id": "a515c63a-0d11-4bcb-a402-39a4600aebb9", "configuration":{"netType":"default","polling_policy":"default","port":"161","collect":1,"threshold":1,"roleType":"default","ping":1,"group":"NMIS9","host":"asgard.opmantek.net","location":null,"customer":null,"businessService":null,"notes":"","host_backup":"","active":null,"community":"","wmiusername":"","wmipassword":"","username":"","context":"","authpassword":"","authkey":"","authprotocol":null,"privpassword":"","privkey":"","privprotocol":null,"serviceStatus":null,"nettype":null,"roletype":null,"node_context_name":"","node_context_url":"","remote_connection_name":"","remote_connection_url":""},"activated":{"opEvents":"1","opConfig":"0","NMIS":"1"},"uuid":null,"current_user_privileges":{"update":true,"delete":true},"name":"test","friendly_addresses":"","friendly_aliases":""}


It will return the json node, the same structure that the CREATE. 

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: 

  • opHA needs to be pulling that peer. This is because the peer sends the API url to update the remote in the registry data. And this information should be updated at least once a day. 
  • The peer has to be online. 

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