[openstack-dev] [ceilometer] Pipeline for notifications does not seem to work

I'm running Juno with ceilometer and trying to produce a new meter which is based on vcpus * F (where F is a constant that is different for each hypervisor).

When I create a VM, I get a new sample for vcpus.

However, it does not appear to fire the transformer.

The same approach using "cpu" works OK but this one is polling on a regular interval rather than a one off notification when the VM is created.

Any suggestions or alternative approaches for how to get a sample based the number of cores scaled by a fixed constant?


In my pipeline.yaml sources,

    - name: vcpu_source
      interval: 180
          - "vcpus"
          - hs06_sink

In my transformers, I have

    - name: hs06_sink
          - name: "unit_conversion"
                    name: "hs06"
                    unit: "HS06"
                    type: "gauge"
                    scale: "47.0"
          - notifier://
