Hi armandom,

I guess this REST api should return what you want:

https://[CONTROLLER_IP]:8443/sdn/v2.0/of/datapaths

Hi vandewilly

thanks for your help but the answer that appears is

{ "datapaths": [ {
      "dpid": ":95:a4",
      "negotiated_version": "1.3.0",
      "ready": "2014-02-11T19:13:15.527Z",
      "last_message": "2014-02-11T22:37:44.693Z",
      "num_buffers": 0,
      "num_tables": 3,
      "device_ip": "192.168.0.2",
      "device_port": 64078,
      "capabilities": [
        "flow_stats",
        "table_stats",
        "port_stats",
        "group_stats",

Hi,

As per the openflow spec (https://www.opennetworking.org/images/stories/downloads/sdn-resources/onf-specifications/openflow/openflow-spec-v1.3.0.pdf ) [page 17], following counters are supported for flow tables and flow entries.

Per Flow Table -

Reference count (active entries)

Packet Lookups

Packet Matches

Per Flow Entry-

Received Packets

Received Bytes

Duration (seconds)

Duration (nanoseconds)

HP VAN SDN Controller does not expose REST API for fetching Per Flow Table Counters however it does expose REST API to get Per Flow Entry counters as shown in attached capture.

Thanks,
