---------------------------------------

             Summary: WebInterface to aggressive in pulling metrics
                 Key: FLINK-5145
                 URL: https://issues.apache.org/jira/browse/FLINK-5145
             Project: Flink
          Issue Type: Improvement
          Components: Webfrontend
    Affects Versions: 1.2.0
            Reporter: Chesnay Schepler
            Assignee: Chesnay Schepler
             Fix For: 1.2.0


The WebInterface currently fetches the values for every available metric in a single request, regardless of whether they are selected or not. For larger jobs with a high parallelism this can put put a big burden on connections.

I propose to limit the polling to metrics that are actually selected.
