GCP Monitoring & Observability Hub 📈

Google Cloud Observability (formerly Stackdriver) provides an integrated, enterprise-scale telemetry suite covering the four pillars of modern observability: Metrics, Logs, Traces, and Continuous Profiles. Engineered to run natively at hyper-scale, it provides full-stack visibility across Google Cloud infrastructure, multi-cloud platforms, and Kubernetes clusters with deep OpenTelemetry (OTel) standard integration.
