How to retrieve the port statistics from ceilometer and the ODL lithium driver

Hi

I have installed OpenStack (Liberty version) on my machine and configured ml2 plugin as an Open daylight controller (Lithium distribution snapshot). I have added the below meters in the /etc/ceilometer/pipeline.yaml file and restart the ceilometer-acentral service. a) switch.port.transmit.bytes b) switch.port.receive.bytes c) switch.port.transmit.packets d) switch.port.receive.packets"

Driver code available in the ceilometer/network/statistics/opendaylight directory is working for all the versions of ODLs(like ithium, beryllium etc).

I am using the "http://localhost:8080/controller/nb/v2/statistics/default/flow" url to fetch the port statistics from the odl and throwing erorr 404.
Please provide some guidances to fetch the port statistics from the ODL lithium distribution.

@praveen - according to the code

"""Driver of network info collector from OpenDaylight.

This driver uses resources in "pipeline.yaml". Resource requires below conditions:

  • resource is url
  • scheme is "opendaylight"

    This driver can be configured via query parameters. Supported parameters:

  • scheme: The scheme of request url to OpenDaylight REST API endpoint. (default http)

  • auth: Auth strategy of http. This parameter can be set basic and digest.(default None)
  • user: This is username that is used by auth.(default None)
  • password: This is password that is used by auth.(default None)
  • container_name: Name of container of OpenDaylight.(default "default") This parameter allows multi vaues.

    e.g.::

    opendaylight://127.0.0.1:8080/controller/nb/v2?container_name=default& container_name=egg&auth=basic&user=admin&password=admin&scheme=http

    In this case, the driver send request to below URLs:

    http://127.0.0.1:8080/controller/nb/v...

    http://127.0.0.1:8080/controller/nb/v...

Hence your pipeline.yaml has to look like:

- name: disk_source
  interval: 600
  resources:
      - opendaylight://127.0.0.1:8080/controller/nb/v2?container_name=default&container_name=egg&auth=basic&user=admin&password=admin&scheme=http
  meters:
      - "switch.port.transmit.bytes"
      - ...
      - "switch.port.receive.bytes"
  sinks:
      - your_sink

Also, please enable debug/verbose in ceilometer.conf to have better visibility on what's going on and share your results.

Good luck!

I am using the beryllium open daylight SDN controller. But when I tried to fetch the flow statistics from the ODL with the below url using curl, I got error code 404. curl -u admin:admin http://localhost:8080/controller/nb/v2/statistics/default/flow (http://localhost:8080/controller/nb/v...)

Even the ceilometer-acentral.log shows the same error message

Is it running|accessible via localhost ? I haven't played with it and don't have env. Hence I recommend to check the endpoint for ODL and enable debug/verbose for ceilometer to have more data.

ODL and Open Stack services are running in the same Machine. ODL can be accessible via localhost.

what about logs? smth new/odd? what odl's docs say about endpoints and statistics?
