Request Modifiers (query parameters)

Not all requests will use all request modifiers.

Query Parameter	Possible Values
`fields_hash`	Array of property names. If provided only the properties specified will be returned (instead of the whole document). eg: `fields_hash={"name":1,"uuid":1}` returns only the node name and the node uuid. By default all properties if no fields_hash is specified.
`page`	Which page of the requested document to be returned, from 1 .. n, defaults to no pagination.
`per_page`	How many results are returned per page, defaults to 25
`search`	List of `key=value` pairs. Search filter applied to the list of results. eg: search={"name":"athena","configuration.group":"SydneyDC"} (which is "Name"="athena" AND "Group"="SydneyDC") For a string, if it starts with regex: or iregex: then a case-sensitive or case-insensitive regular expression match is used. eg: filter={"name":"iregex:Switch"} to find all the nodes with switch or SWITCH in their name.
`sort_by`	Property to sort by. eg: sort_by=name to sort by node name
`order`	Sort order. asc \| desc : sort the response by sort_by ascending or descending.

By example, the queries will look something like this:

http://athena.opmantek.net/omk/admin/api/v2/nodes.json?fields_hash={"name":1,"uuid":1}&search={"name":"Switch-1"}

Authentication

Important: All these methods are authenticated.

Operation

Response

Example

Authenticate

POST

http://host/en/omk/admin/login

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

Code Block
{"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 Remote

POST

http://host/en/omk/admin/api/v2/nodes.json

It 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:

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