>          Components: Spark Core
>    Affects Versions: 1.4.0

> There is a number of user questions posted into the Spark mailing list regarding how to instrument custom metrics within Spark applications:
> * how to define custom metrics
> * how to define a custom metrics sink such as a custom metrics servlet
> * how to call back into the consumers from the sink to report on some actions potentially taken by the metrics sink
> Some of this may be a documentation issue. Currently the Metrics section under https://spark.apache.org/docs/latest/monitoring.html is rather sparse.
