Host monitoring

Host monitoring collects host metrics and process data from Kubernetes nodes. It deploys OneAgent to capture metrics such as CPU, memory, disk, and network usage. This mode does not include application-level monitoring.

See the .spec.oneAgent.hostMonitoring section of DynaKube for additional information.

Capabilities

Collects host metrics and process data.

Limitations

Diagnostic files (support archives) for application pods aren't yet supported for read-only file systems.

Deployed resources

Dynatrace Operator components

The following components are deployed via Helm/Manifests as part of the core installation. For more information, go to their respective sections:

  • Dynatrace Operator manages the automated rollout, configuration, and lifecycle of Dynatrace components in your Kubernetes environment.
  • Dynatrace Operator webhook validates DynaKube definitions, converts definitions with older API versions, and injects configurations into pods.
  • Dynatrace Operator CSI Driver deployed as a DaemonSet, provides writable volume storage for OneAgent binaries to minimize network and storage usage.

Operator-managed components

The following components are deployed by applying a DynaKube with full-stack observability:
