Managed OpenTelemetry for GKE generally available on 1.37.1-gke.1697000 or later

Managed OpenTelemetry for GKE is generally available (GA) on clusters running GKE version 1.37.1-gke.1697000 or later. You can collect OpenTelemetry Protocol (OTLP) traces, metrics, and logs from your workloads with a Google-managed collector instead of a self-managed OpenTelemetry Collector deployment:

• Configure otlp_grpc in the Instrumentation custom resource (GKE version 1.37.1-gke.1697000 or later), or send telemetry directly to the in-cluster collector's gRPC endpoint on port 4317 in addition to HTTP on port 4318.
• The managed collector routes logs alongside traces and metrics through the Cloud Telemetry API (telemetry.googleapis.com), with improved per-signal queueing and autoscaling for high-throughput clusters. (Logs ingested through telemetry.googleapis.com default to the otlp log name instead of gke-managed-otel-collector.)
• Multimodal prompts and responses collection for LangGraph ReAct and Agent Development Kit (ADK) agents, the --managed-otel-scope flag in the gcloud CLI (version 576.0.0 or later), and managed_opentelemetry_config in terraform-provider-google (v8.8.0 or later) are generally available.

To use the GA collector and features, upgrade clusters from earlier Preview versions to 1.37.1-gke.1697000 or later. For architecture details and setup instructions, see Managed OpenTelemetry for GKE and Deploy Managed OpenTelemetry for GKE.
