I just found another bug related to forked-chains. Right now only the
output of a single operator is used as the task output counter, where as we
should actually use both of them. Will fix it while merging.

> URL: https://issues.apache.org/jira/browse/FLINK-4733
> Project: Flink
> Issue Type: Improvement
> Components: Metrics, TaskManager, Webfrontend
> Affects Versions: 1.1.2
> Reporter: Chesnay Schepler
> Assignee: Chesnay Schepler
> Fix For: 1.2.0
>
>
> While the WebFrontend has access to the metric system it still relies on
> older code in some parts.
> The TaskManager metrics are still gathered using the Codahale library and
> send with the heartbeats.
> Task related metrics (numRecordsIn etc) are still gathered using
> accumulators, which are accessed through the execution graph.
