You could define these as a `ConfigOption` which would make it more obvious
what the default value is.
> Add Datadog HTTP metrics reporter
> ---------------------------------
>
> Key: FLINK-6013
> URL: https://issues.apache.org/jira/browse/FLINK-6013
> Project: Flink
> Issue Type: Improvement
> Components: Metrics
> Affects Versions: 1.3.0
> Reporter: Bowen Li
> Assignee: Bowen Li
> Priority: Critical
> Fix For: 1.3.0
>
>
> We at OfferUp use Datadog a lot for metrics and dashboards, and I believe a
> lot other companies also do.
> Flink right now only has a StatsD metrics reporter, and users have to set up
> Datadog Agent in order to receive metrics from StatsD and transport them to
> Datadog. We don't like this approach.
> We prefer to have a Datadog metrics reporter directly contacting Datadog http
> endpoint.
> I'll take this ticket myself.
