How to distribute load between pollers

HCO provides ability to distribute load between Polling engines. Node polling is assigned to a specific Poller Engine and can be moved between Poller Engines later via SDK.

Headers

Authorization: {{basicAuthorization}}

Example Response

{
    "results": [
        {
            "EngineID": 1,
            "ServerName": "Hostname1",
            "IP": "10.10.10.10",
            "ServerType": "Primary",
            "Elements": 3
        },
        {
            "EngineID": 2,
            "ServerName": "Hostname2",
            "IP": "10.10.10.11",
            "ServerType": "Additional",
            "Elements": 6
        }
    ]
}

Elements property shows the number of elements (Nodes, Interfaces, etc.) assigned to the Polling engine.

Assign node to specific Polling engine

Orion.Nodes.Uri is needed to specify the Node to change Polling engine for.
