You can update the `FlowCollector` API resource to configure the Network Observability Operator and its managed components. The `FlowCollector` is explicitly created during installation. Since this resource operates cluster-wide, only a single `FlowCollector` is allowed, and it must be named `cluster`.

Installing the Loki Operator is recommended before using the Network Observability Operator. You can use network observability without Loki, but special considerations apply if you only need metrics or external exporters.

Installing Loki is a recommended prerequisite for using the Network Observability Operator. You can choose to use xref:../../observability/network_observability/installing-operators.adoc#network-observability-without-loki_network_observability[Network observability without Loki], but there are some considerations for doing this, described in the previously linked section.

The {loki-op} integrates a gateway that implements multi-tenancy and authentication with Loki for data flow storage. The `LokiStack` resource manages Loki, which is a scalable, highly-available, multi-tenant log aggregation system, and a web proxy with {product-title} authentication. The `LokiStack` proxy uses {product-title} authentication to enforce multi-tenancy and facilitate the saving and indexing of data in Loki log stores.

Red Hat offers cluster administrators and developers the Network Observability Operator to observe the network traffic for {product-title} clusters. The Network Observability Operator uses the eBPF technology to create network flows, which are then enriched with {product-title} information. The flows are available as Prometheus metrics or as logs in Loki. You can view and analyze this stored information in the {product-title} console for further insight and troubleshooting.
