What feature allows Dynatrace to monitor only selected namespaces in Kubernetes?

The feature that allows Dynatrace to monitor only selected namespaces in Kubernetes is custom namespace monitoring. This functionality provides the flexibility to focus on specific areas of your Kubernetes environment, allowing for targeted performance monitoring and insights without the need to process data for the entire cluster. By selecting specific namespaces, users can enhance performance, reduce noise from unwanted metrics, and streamline the analysis process, ultimately leading to more actionable insights relevant to the services and applications of interest.

Cluster-wide monitoring typically involves tracking and analyzing performance metrics across the entire Kubernetes cluster, which does not provide the granularity needed to focus on particular namespaces. Node metrics aggregation is more about collecting data from multiple nodes rather than focusing on specific namespaces. Dynamic service discovery, while it helps in identifying services as they scale up or down, does not specifically address the limitation of monitoring only certain namespaces. Hence, custom namespace monitoring is the right choice for targeting particular operational areas in the Kubernetes landscape.
