How to capture all metrics using IMetricsConsumer?

Question

I created an implementation IMetricsConsumerand registered it in my topology through YAML as follows. Any custom metrics that I created in my own code are successfully passed to this user.

  topology.metrics.consumer.register:
    - class: "hnb.storm.metric.opentsdb.OpenTsdbMetricConsumer"
      parallelism.hint: ${storm.topology.metrics.consumer.parallelism}

Unfortunately, other "external" metrics created outside of my code are never passed to this consumer. For example, I use storm.kafka.KafkaSpoutone that creates its own metric called kafkaOffsetusing the same API. My consumer never gets this rate.

How to ensure that my consumer receives "external" indicators, such as kafkaOffset?
