Data storage As we mentioned above, Cassandra stores some of its data in RAM, in the form of MemTable. ![]() How can i make the Java agent JMX exporter to run long, until the driver and executors completed the job. The JMX exporter can export from a wide variety of JVM-based applications, for example Kafka and Cassandra. Promethues is able to register these pod's URL in the prometheus, but when it is trying to scrape the metrics(runs for every 30 seconds), the pod's URL is down. This is a Docker container intended to be run in the same pod as your Java containers, to export their metrics for Prometheus. Java Management Extensions, JMX, is an extension framework for managing Java, and JMX Exporter is based on this framework for reading the runtime state of the JVM. For more information, see prometheus/jmxexporter. Learn how to use Prometheus with JMX Exporter to monitor Java applications once your Java business has been containerized to Kubernetes in this article. Java agent is exposing the metrics on port 8090 for a short time (I can validate that with port-forwarding kubctl port-forward 8090:8090 ), also the service is also exposing the metrics for few mins ( can validate that with port-forwarding kubctl port-forward svc/ 8090:8090 ).
