> Whitelist mechanism for StatsD metrics
> --------------------------------------
>
> Key: AIRFLOW-5508
> URL: https://issues.apache.org/jira/browse/AIRFLOW-5508
> Project: Apache Airflow
> Issue Type: New Feature
> Components: scheduler
> Affects Versions: 1.10.5
> Reporter: Mike Dias
> Assignee: Mike Dias
> Priority: Minor
>
> Sometimes we don't need that all available metrics be sent to StatsD server
> when only a particular subset is relevant (e.g. scheduler or pool).
> One of the reasons for filtering out metrics is because some of them are
> based on dag ids, creating high cardinality metrics in the StatsD server,
> leading into scalability issues in an environment with many dags.
> This feature aims to give the users the ability to control which metrics
> should be sent via whitelisting, keeping the default behavior of sending all
> if not specified.
