how to get the node connector statistics(ReceiveBytes& TransmitBytes) of every node. Below is my method, but I cannot got node connector statistics

 GetAllNodeConnectorsStatisticsInputBuilder b = new GetAllNodeConnectorsStatisticsInputBuilder();
            InstanceIdentifier<Nodes> nodeIdentifier = InstanceIdentifier.builder(Nodes.class).toInstance();
            Nodes nodeList = (Nodes) dataService.readOperationalData(nodeIdentifier);
            if(nodeList != null){
                for(Node n : nodeList.getNode()){
                    InstanceIdentifier<Node> iNode = InstanceIdentifier
                    NodeRef nr = new NodeRef(iNode);
                    Future<RpcResult<GetAllNodeConnectorsStatisticsOutput>> o = portStatisticsService.getAllNodeConnectorsStatistics(;
                        RpcResult<GetAllNodeConnectorsStatisticsOutput> ro = o.get();
                        GetAllNodeConnectorsStatisticsOutput nro = ro.getResult();
                        List<NodeConnectorStatisticsAndPortNumberMap> nrolist = nro.getNodeConnectorStatisticsAndPortNumberMap();
                        if(null != nrolist){
                            for(NodeConnectorStatisticsAndPortNumberMap nodeConnectorStatistics : nrolist){
                    }catch(Exception e){

there is the method that got node connector statistics from each node. In this code, O return null,

 Future<RpcResult<GetAllNodeConnectorsStatisticsOutput>> o = portStatisticsService.getAllNodeConnectorsStatistics(;

and also NodeConnectorStatisticsAndPortNumberMap return null.

So I wonder know is that method getting wrong or just argument was not sending.

Hi shangheng, I am also tring to get current speed of node connector.By instantiating FlowCapableNodeConnector.But i am also getting null values.Have you succeeded in your approach. please let me know. Regards,

It's a best practice to only ask one question per question. A more descriptive title would likely get more attention from people who know the domain in question. It's also likely that someone would need more info, especially for question one.
