Subject [jira] [Created] (AIRFLOW-5508) Whitelist mechanism for StatsD metrics
Date Tue, 17 Sep 2019 01:27:00 GMT
Mike Dias created AIRFLOW-5508:

             Summary: Whitelist mechanism for StatsD metrics
                 Key: AIRFLOW-5508
             Project: Apache Airflow
          Issue Type: New Feature
          Components: scheduler
    Affects Versions: 1.10.5
            Reporter: Mike Dias
            Assignee: Mike Dias

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.
