The Apache Cassandra JMX server monitoring extension in Dynatrace provides information about database exceptions, failed requests, performance, and more. If Cassandra is underperforming or a problem occurs, Dynatrace lets you know immediately and shows you which nodes are affected.
This is a JMX (Java Management Extension) Dynatrace extension. JMX is ideal for monitoring applications built using Java.

The dashboard Cassandra JMX Overview will be included in the extension. From there, you can navigate to the list of all the entities Cassandra instances created by the extension. Each individual entity will have its own screen to view its metrics and navigate to the related process.
Additionally, all metrics captured by the extension will be appended to the process group instance unified analysis screen in three new sections: JMX Exception Metrics, JMX Usage Metrics and JMX ThreadPool Metrics. Make sure to be on the new screen for process group instances to see them.
All metrics can also be viewed with the data explorer.
