> 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.
