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. Make sure you are monitoring your Cassandra process as the extension does not support gathering metrics from the client-side.

Output
The dashboard Cassandra JMX Overview will be included in the extension, where you can see an overview of your Cassandra JXM metrics.
Additionally, all metrics captured by the extension will be appended to the process group instance unified analysis screen in three new sections: Exceptions, Usage and Thread Pool. 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.
Licensing Consumption
The extension consumes DDU Units. However, they are elgible for the free tier included with every host.
The amount of DDUs units depends on the number of instances monitored.
