---------------------------------------
Github user tillrohrmann commented on the issue:
https://github.com/apache/flink/pull/4647
The next time we touch `MutableIOMetrics`, we should also refactor
`MutableIOMetrics#addIOMetrics` such that one passes an IOMetrics object into
it instead of the `MetricFetcher`.
> Dashboard jobs/tasks metrics display 0 when metrics are not yet available

> URL: https://issues.apache.org/jira/browse/FLINK-7575
> Project: Flink
> Issue Type: Improvement
> Components: Webfrontend
> Affects Versions: 1.3.2
> Reporter: James Lafa
> Assignee: James Lafa
> Priority: Minor
> Fix For: 1.4.0

>
> The web frontend is currently displaying "0" when a metric is not available
> yet (ex: records-in/out, bytes-in/out).
> 0 is misleading and it's preferable to display no value while the value is
> still unknown.
