             Summary: Provide access to low-level Metrics in ProcessorContext
                 Key: KAFKA-3537
                 URL: https://issues.apache.org/jira/browse/KAFKA-3537
             Project: Kafka
          Issue Type: New Feature
          Components: streams
    Affects Versions: 0.9.0.1
            Reporter: Michael Coon
            Assignee: Guozhang Wang
            Priority: Minor


It would be good to have access to the underlying Metrics component in StreamMetrics. StreamMetrics forces a naming convention for metrics that does not fit our use case for reporting. We need to be able to convert the stream metrics to our own metrics formatting and it's cumbersome to extract group/op names from pre-formatted strings the way they are setup in StreamMetricsImpl. If there were a "metrics()" method of StreamMetrics to give me the underlying Metrics object, I could register my own sensors/metrics as needed.
