[jira] [Created] (BEAM-4178) Metric doesn't appear until first changed

Kevin Peterson created BEAM-4178:
------------------------------------

             Summary: Metric doesn't appear until first changed
                 Key: BEAM-4178
                 URL: https://issues.apache.org/jira/browse/BEAM-4178
             Project: Beam
          Issue Type: Bug
          Components: beam-model, sdk-java-core
    Affects Versions: 2.4.0
         Environment: Java, DataflowRunner
            Reporter: Kevin Peterson
            Assignee: Kenneth Knowles


When defining a counter Metric, I've noticed that the Metric does not show up in the Dataflow UI (or stackdriver) until it is first incremented or decremented.

Ideally, some initial value for the metric should be reported when the pipeline is started.

The specific use case I have in mind is setting up a Stackdriver alert for a error condition in the pipeline. But because the metric doesn't show up until an error actually happens, I can't set the metric up in advance.
