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
      meters:
          - "vcpus"
      sinks:
          - hs06_sink

In my transformers, I have

    - name: hs06_sink
      transformers:
          - name: "unit_conversion"
            parameters:
                target:
                    name: "hs06"
                    unit: "HS06"
                    type: "gauge"
                    scale: "47.0"
      publishers:
          - notifier://
