API Basics


(for full API, see Red5 Pro Stream Manager API)

Verify Stream Manager is Using the Correct Controller

GET call:

http://<streammanager_IP>:5080/streammanager/api/4.0/admin/debug/cloudcontroller?accessToken=<rest.administratorToken from red5-web.properties file>

should return: Microoft Azure

Create a New Node Group (post)

Using a tool like Postman, create a new node group via the API.

Not all regions may support virtual machines based on the nature of your subscription. You would need to check with Azure support about the limitations of your subscription.

POST call:

http://<streammanager_IP>:5080/streammanager/api/4.0/admin/nodegroup?accessToken=<rest.administratorToken from red5-web.properties file>

Data (make sure to select JSON as the body type):

{
 "regions": [
   "eastus"
 ],
 "launchConfig": "az-default-v2",
 "scalePolicy": "default-v2"
}

Note the cluster “name” that is returned by the above call. It will be used to create a new Origin server.

Launch New Origin (post) After you create a node group, create the origin server. Creating an origin server will also generate at least one edge, per scaling policy min limit.

Set Alarm Threshold (POST)

By default, the alarm threshold (the capacity percentage at which the cluster will scale up) is set to 60%. To modify this, POST the following:

FOR EDGE:

http://<streammanager_IP>:5080/streammanager/api/4.0/admin/alarm/scaleout/default?type=edge&threshold=<threshold>&accessToken=<rest.administratorToken from red5-web.properties file>

FOR ORIGIN:

http://<streammanager_IP>:5080/streammanager/api/4.0/admin/alarm/scaleout/default?type=origin&threshold=<threshold>&accessToken=<rest.administratorToken from red5-web.properties file>

LIST GROUPS (get)
