Amazon EKS makes running containerized applications easier, but it doesn’t give you automatic visibility into JVM internals like memory usage or garbage collection. For Java applications, observability requires two levels of integration:

Cluster-level monitoring for pods, nodes, and deployments
JVM-level APM instrumentation for heap, GC, threads, latency, etc.

New Relic provides both via Helm for infrastructure metrics, and a lightweight Java agent for full JVM observability.
