             Summary: Convert to Codahale Metric interfaces where possible in WithMetricsSupport MetricRegistry
                 Key: BEAM-1692
                 URL: https://issues.apache.org/jira/browse/BEAM-1692
             Project: Beam
          Issue Type: Improvement
          Components: runner-spark
            Reporter: Aviem Zur
            Assignee: Aviem Zur
            Priority: Minor


Currently in Spark runner all Beam metrics are reported by Codahale metrics as Codahale {{Gauge}}s.
Some of the metrics are formatted to look like their counterparts in Codahale's {{GraphiteReporter}} but this is a hack and should be avoided if possible.

Instead, convert Beam metrics to their Codahale counterparts in {{WithMetricsSupport}} getters where possible.

Since Beam metrics are not 100% compatible with Codahale metrics, consider where to make tradeoffs and stay with a simple {{Gauge}}.
