+### Reporting Metrics using Dropwizard
+Spark supports reporting metrics using the [Dropwizard
Library](monitoring.html#metrics). To enable metrics of Structured Streaming
queries to be reported as well, you have to explicitly enable the configuration
`spark.sql.streaming.metricsEnabled` in the SparkSession.
