This Splunk OpenTelemetry Collector for Kubernetes release adopts the Splunk OpenTelemetry Collector v0.131.0.

🛑 Breaking changes 🛑

• agent, clusterReceiver: Changed the default value of the 'useControlPlaneMetricsHistogramData' and 'enableEKSApiServerMetrics' feature gates. These feature gates now default to true and only affect Kubernetes control plane metrics collection. (#1944)
  • Enabling 'featureGates.useControlPlaneMetricsHistogramData' switches the agent's control plane metrics collection from the legacy smartagent/* receivers to prometheus/* receivers for k8s control plane components (apiserver, controller-manager, scheduler, etcd, kube-proxy, coredns).
    • This change also enables sending histogram metrics from the above-listed k8s components as OTLP histograms to Splunk Observability.
    • To disable this feature, set featureGates.useControlPlaneMetricsHistogramData to false.
  • The 'featureGates.enableEKSApiServerMetrics', now set to true, controls whether EKS API server metrics are collected and sent to Splunk Observability, including OTLP histograms.
    • This change only affects clusterReceiver deployments running in EKS (including vanilla, Fargate, or Auto Mode) clusters.
    • To disable this feature, set featureGates.enableEKSApiServerMetrics to false.
  • Please review your configuration if you relied on the previous default of false for these feature gates.
