## Operating across multiple clusters

If you are running this setup across more than a handful of clusters, see the guide on [Managing OpenTelemetry Collector Configuration Across Multiple Clusters](https://last9.io/guides/opentelemetry/managing-otel-collector-configuration-across-clusters/) for directory layout, per-tenant overrides, secrets handling, and apply workflow patterns.
