Fixed In Version: openstack-ceilometer-2013.2-0.2.b1.el6ost Doc Type: Enhancement
Doc Text:
A public RESTful API to accept incoming sample datapoints has been added to OpenStack Metering. This was required because it is often more convenient for user-level agents to emit statistics to Ceilometer via a public API, than to gain access to the AMQP bus. Now, samples may be POSTed to the "/v2/meters/<meter_name>" endpoint.

Description Eoghan Glynn 2013-07-25 12:02:47 UTC 
Allow metering samples to be submitted directly to the ceilometer-api via a RESTful interface (as opposed to everything being collected over AMQP).

Heat and Ceilometer tests will be performed mainly by Dev

How To Test
===========

0. Install packstack allinone in the usual way.


1. Submit a sequence of samples for a fabricated meter:

  for i in $(seq 5)
  do
    ceilometer sample-create -r foobar -m instance_likes \
      --meter-type delta --meter-unit thumbs_up --sample-volume $i \
      --resource-metadata '{"image_id": "cirros", "vcpus": "1", "display_name": "test_server", "ram": "512"}' \
      --timestamp $(date -u +"%Y-%m-%dT%H:%M:%SZ")
    sleep 1
  done


2. Ensure that the samples are all reported correctly:

   ceilometer sample-list -m instance_likes

   The correct number of samples should be reported, with the volumes in descending order.


3. Ensure that samples are aggregated as expected:

   ceilometer statistics ceilometer sample-list -m instance_likes

   Check that the aggregates reported are sane:

     count: 5
     min:   1
     max:   5
     sum:   sigma n (n <= 5)
     avg:   3


4. Ensure that the project and user IDs for the submitted samples can only be set to another indentity by admin:

  export OS_USERNAME=demo
  export OS_TENANT_NAME=demo
  export OS_PASSWORD=<DEMO_PASSWORD>

  ceilometer --debug sample-create -r foobar -m instance_likes \
    --meter-type delta --meter-unit thumbs_up --sample-volume 6 \
    --resource-metadata '{"image_id": "cirros", "vcpus": "1", "display_name": "test_server", "ram": "512"}' \
    --timestamp $(date -u +"%Y-%m-%dT%H:%M:%SZ") \
    --project-id foo --user-id bar

  Should fail with:
 
  ...
  {"error_message": {"debuginfo": null, "faultcode": "Client", "faultstring": "Invalid input for field/attribute project_id. Value: 'project_id'. can not post samples to other projects"}}
