OpenTelemetry overview

What Obsy deploys

For each Kubernetes cluster you register, Obsy installs:

Component	Type	Role
OTel Gateway	`Deployment` (1+ replicas)	Receives OTLP from your services; applies sampling, filtering, and batching; exports to Datadog/Grafana
Node Collector	`DaemonSet` (one per node)	Collects host metrics, kubelet stats, and container logs from every node

Both are deployed to the obsy-system namespace via the official open-telemetry/opentelemetry-collector Helm chart.
