Apache Spark reassigned SPARK-11373:
------------------------------------
Assignee: Apache Spark
> Add metrics to the History Server and providers
> -----------------------------------------------
>
> Key: SPARK-11373
> URL: https://issues.apache.org/jira/browse/SPARK-11373
> Project: Spark
> Issue Type: New Feature
> Components: Spark Core
> Affects Versions: 1.5.1
> Reporter: Steve Loughran
> Assignee: Apache Spark
>
> The History server doesn't publish metrics about JVM load or anything from
> the history provider plugins. This means that performance problems from
> massive job histories aren't visible to management tools, and nor are any
> provider-generated metrics such as time to load histories, failed history
> loads, the number of connectivity failures talking to remote services, etc.
> If the history server set up a metrics registry and offered the option to
> publish its metrics, then management tools could view this data.
> # the metrics registry would need to be passed down to the instantiated
> {{ApplicationHistoryProvider}}, in order for it to register its metrics.
> # if the codahale metrics servlet were registered under a path such as
> {{/metrics}}, the values would be visible as HTML and JSON, without the need
> for management tools.
> # Integration tests could also retrieve the JSON-formatted data and use it as
> part of the test suites.
