             Summary: Introduce generic metric poll thread interceptor
                 Key: BEAM-2456
                 URL: https://issues.apache.org/jira/browse/BEAM-2456
             Project: Beam
          Issue Type: New Feature
          Components: sdk-ideas
            Reporter: Jean-Baptiste Onofré
            Assignee: Jean-Baptiste Onofré


The Spark runner provides a convenient feature which is the metric sink.

By configuration, it allows us to configure a metric sink using {{metrics.properties}} configuration containing:

{code}
driver.sink.graphite.class=org.apache.beam.runners.spark.metrics.sink.GraphiteSink
driver.sink.graphite.host=localhost
driver.sink.graphite.port=2003
driver.sink.graphite.prefix=spark
driver.sink.graphite.period=1
driver.sink.graphite.unit=SECONDS 
{code}

This approach is very convenient to send the metric to any sink. I think we can apply this logic in generic way working with any runner.

The idea is to use a metric poll thread in the pipeline (that we can enable via {{PipelineOptions}}) and send to a sink.

I started a PoC about that.
