I'm trying to get statistics using the following RPC call and not via the default statistics-manager.

POST /restconf/operations/opendaylight-flow-statistics:get-all-flows-statistics-from-all-flow-tables { "input": { "node" : "/opendaylight-inventory:nodes/opendaylight-inventory:node[opendaylight-inventory:id=\"openflow:1000\"]" } }

However, the response of this request is just "transaction-id". While I can see the OpenFlow "Flow Stat Request" and "Flow Stat Reply" messages are exchanged between the controller and the switch, the operational datastore seems not to be updated as a result of calling the above RPC. I check the operational datastore using: GET /restconf/operational/opendaylight-inventory:nodes/node/openflow:1000/table/0

My question is - how can I get the flow statistics sent to the controller by the switch as a result of the above RPC (get-all-flows-statistics-from-all-flow-tables)? And why is the operational datastore is not updated?

Thanks! Michael.

Using Boron, what you're trying to use is deprecated, hence you should use the following:

  1. Install odl-openflowplugin-flow-services
  2. Connect your switch
  3. Send the following request:

    POST /restconf/operations/opendaylight-direct-statistics:get-node-connector-statistics
    Host: localhost:8181
    Content-Type: application/json
    Authorization: Basic YWRtaW46YWRtaW4=
            "node" : "/opendaylight-inventory:nodes/opendaylight-inventory:node[opendaylight-inventory:id=\"openflow:187811733353539\"]" ,
            "store-stats" : false
  4. Set store-stats to true if you want to keep them in the datastore.

You can also get the stats only for a specified port, but while trying, it appears not to be working well Add this to the above payload:

    "node-connector-id" : "/opendaylight-inventory:nodes/opendaylight-inventory:node[opendaylight-inventory:id=\"openflow:187811733353539\"]/opendaylight-inventory:node-connector[opendaylight-inventory:id='openflow:187811733353539:LOCAL']",

Instead of LOCAL, specify the port you want.

Hope this helps, Alexis

Thank you very much for the suggestion. Unfortunately we are using Lithium release since in Beryllium, there is a "role request" sent after "feature request". Our switches do not support "role request", so connection to controller terminates. Is there is a way to skip "role request" in Boron?
