Sunset Node

Description

The sunset node API call has been added to the Stream Manager to allow the Node Checker, or a user, to report an edge node which is not properly working. When the edge is reported, the Stream Manager will stop forwarding new subscribers to it and it will create a new edge to compensate for the capacity loss. At the same time, the Stream Manager will monitor the existing clients of a reported edge and once all of them disconnect, it will terminate the edge.

REQUEST

• URI: https://<stream-manager-hostname>/streammanager/api/4.0/admin/node/sunset?accessToken=<accessToken>
• Method: POST
• Data: JSON

    [
      "{node-instance-ip}"
    ]

RESPONSE

• Success: HTTP CODE 200

• Method: POST
• Data: JSON

    [
      "192.168.1.1"
    ]

RESPONSE

• Success: HTTP CODE 200

Terminate Node

Description

Terminates a node by its host address. This requires that the node is in the INSERVICE state. If a node is already in terminating state or is a newly launched node it cannot be terminated until it becomes active (attains the INSERVICE state).

Optionally you can force delete a node using the boolean query parameter force if it is stuck in a transitioning state for long and you ar eunable to terminate it normally. The value for the parameter force can be true or false. This will remove the node entry from database and streammanager will delete it from cloud after some time.

REQUEST

• URI: https://<stream-manager-hostname>/streammanager/api/4.0/admin/node/<host-address>?accessToken=<accessToken> OR https://<stream-manager-hostname>/streammanager/api/4.0/admin/node/<host-address>?accessToken=<accessToken>&force=true
