Monitoring Spark Applications
To obtain information about Spark application behavior you can consult cluster manager logs and the Spark web application UI. These two methods provide complementary information.
Logs enable you to see fine grained events in the lifecycle of an application. The web UI provides both a broad overview of the various aspects of Spark application behavior and fine grained metrics. This section provides an overview of both methods.
For further information on Spark monitoring, see the Spark documentation on monitoring and instrumentation.
