[OPNFLWPLUG-31] Queue list for a node connector is always empty

Blocks — Mon, 27 Sep 2021 09:01:01 +0000

1. add queue for a port using mininet:

sudo ovs−vsctl −− set port s1-eth1 qos=@newqos −− −−id=@newqos create qos type=linux−htb other−config:max−rate=1000000 queues:0=@newqueue −− −−id=@newqueue create queue other−config:min−rate=1000000 other−config:max−rate=1000000

2. read queue operational data as shown below, queue list is always empty.
InstanceIdentifier<FlowCapableNodeConnector> connectorRef = InstanceIdentifier.builder(Nodes.class)
.child(Node.class, nodeKey).child(NodeConnector.class, nodeConnectorKey)
.augmentation(FlowCapableNodeConnector.class).toInstance();

FlowCapableNodeConnector nodeConnector =
(FlowCapableNodeConnector) dataProviderService.readOperationalData(connectorRef);

List<Queue> queueList = nodeConnector.getQueue();

queueList is always empty.

3. we are able to see queue stats using REST API
http://localhost:8080/restconf/operational/opendaylight-inventory:nodes/node/openflow:1/node-connector/openflow:1:1/
