We’re happy to announce the beta availability of Spark monitoring! Apache Spark monitoring provides insight into the resource usage, job status, and performance of Spark Standalone clusters.
Monitoring is available for the three main Spark components:
- Cluster manager
- Driver program
- Worker nodes
Apache Spark metrics are presented alongside other infrastructure measurements, enabling in-depth cluster performance analysis of both current and historical data.
To view Spark monitoring insights
- Click Technologies in the menu.
- Click the Spark tile.
- To view cluster metrics, expand the Details section of the Spark process group.
- Click the Process group details button.
- On the Process group details page, click the Technology-specific metrics tab. Here you’ll find metrics for all Spark components.
- Further down the page, you’ll find a number of other cluster-specific charts.

Spark node/worker monitoring
To access valuable Spark node metrics:
- Select a worker from the Process list on the Process group details page (see example below).
- Click the Apache Spark worker tab.
Spark Worker metrics

- Dynatrace OneAgent version 1.105+
- Linux OS or Windows
- Spark Standalone cluster manager
- Spark version 1.6
- Enabled JMX monitoring metrics. Turn on
JmxSinkfor all instances by class names:
org.apache.spark.metrics.sink.JmxSink conf/metrics.propertiesFor more details, see Spark documentation.
- To recognize your cluster,
SparkSubmitmust be executed with the
–masterparameter and master host address. See example below:
--class de.codecentric.SparkPi \
--master spark://192.168.33.100:7077 \
--conf spark.eventLog.enabled=true \
Enable Spark monitoring globally
With Spark monitoring enabled globally, Dynatrace automatically collects Spark metrics whenever a new host running Spark is detected in your environment.
- Go to Settings > Monitoring > Monitored technologies.
- Set the Spark switch to On.
