 NetObserv is a set of components used to observe network traffic by generating NetFlows from [eBPF agents](https://github.com/netobserv/netobserv-ebpf-agent), enriching those flows using [a configurable pipeline](https://github.com/netobserv/flowlogs-pipeline/) which is Kubernetes-aware, exporting them in various ways (logs, metrics, Kafka, IPFIX...), and finally providing a comprehensive [visualization tool](https://github.com/netobserv/network-observability-console-plugin/) for making sense of that data, and [a CLI](https://github.com/netobserv/network-observability-cli). Those components can be used as standalones or deployed in Kubernetes / OpenShift via an [integrated Operator](https://github.com/netobserv/network-observability-operator/).
 
 It is known and distributed in Red Hat OpenShift as the [Network Observability operator](https://docs.openshift.com/container-platform/latest/observability/network_observability/network-observability-operator-release-notes.html).
