Standalone eBPF network observability and emergency network control for Linux/Kubernetes — with optional Cilium + Hubble enrichment. Kernel drop attribution, path and congestion diagnostics, live packet capture, and leased deny rules that return to observe on their own, on any CNI.
Observe-first · Lease-bounded, fails open · No CNI required · No payload collection · 190 MCP tools

From CHANGELOG.md (0.28.2 to 0.30.0):
| Per-second metrics *(0.30.0)* | Host, network, cgroup, process-group, eBPF and workload RED series every second, with anomaly detection, metric alerts, app collectors, exporters, and a link from any chart spike to the flows and drops behind it. Docs → |
| Node isolation *(0.30.0)* | A per-node allow-only egress filter in shadow (count what it would block) or enforce, as a standalone TCX program. Docs → |
| Security review *(0.30.0)* | DNS query types, versioned threat feeds with expiry, rollback and optional HTTPS refresh, deny-predicate overlap review and exact-workload incident correlation. Docs → |
| L7 metadata on current kernels *(0.30.0)* | TLS SNI, HTTP Host and DNS names load again on Linux 6.8+ (they were rejected by the verifier), using bpf_loop on Linux 5.17+. Docs → |
| Netlink change recorder | Which link, address, route or neighbor changed on a node, and when, across every routing table. Docs → |
| Netlink findings and alerts | Default route removed, gateway unreachable, uplink down, MTU changed, derived from the recorded changes. |
| Who made the change | An fentry on rtnetlink_rcv_msg attributes each modifying netlink request to the process that sent it. |
| BPF attachment inventory | Netra notices when its own hooks have silently gone, for example after a NIC or bond is recreated. Docs → |
| One UX contract | Dashboard and docs site follow one design contract; Apple light by default, dark one click away. |
| Stable controller certificate | tls.existingSecret serves a kubernetes.io/tls Secret so clients can pin the controller certificate. |
| When this happens… | Netra gives you… |
|---|---|
| Traffic disappears and nobody can say where | Kernel drop attribution: the connection, the reason, and the kernel function that dropped it |
| You need to act now, but enforcement is scary | Leased deny that reverts by itself, previewed against live traffic first |
| Your CNI is not Cilium, or you cannot change it | cgroup v2 hooks that work on any CNI, with no kernel module and no app changes |
| "The network is slow" with no evidence | TCP path diagnostics and a Congestion Map that colors every layer of the Linux network stack by its worst finding |
| A chart spiked and you need to know why | Per-second metrics with anomaly detection, where every spike links to the flows, drop reasons and captures from that window |
| You need packets from one node, now | Filtered, time-bounded live capture with a Wireshark-style layered decode, one click from a finding |
| Your AI agent should investigate without breaking things | An MCP server with 190 tools; mutations stay behind NETRA_MCP_ALLOW_MUTATIONS |
Netra does not require Cilium. The node agent owns its own programs and maps below /sys/fs/bpf/netra. If Cilium/Hubble exists, Netra can manage CiliumNetworkPolicy and display Hubble flows, but both integrations are opt-in.
| Netra | Cilium + Hubble | |
|---|---|---|
| What it is | Observability and emergency control that runs next to your CNI | A CNI with Hubble observability built on its datapath |
| Adoption | Helm install of a controller and a node agent DaemonSet; no CNI change | Cilium becomes the cluster's CNI |
| Kernel hooks | cgroup skb, connect/sendmsg, sockops; optional kfree_skb, TCX and XDP | Cilium's own eBPF datapath |
| Enforcement model | Leased deny that returns to observe when the lease expires or the controller loses state | Network policies persist until removed |
| Drop diagnosis | Kernel drop reason and dropping function per connection, plus Drop Explain | Hubble flow verdicts and drop reasons from the Cilium datapath |
| Plain Linux hosts | The same agent and hooks | Built around Cilium-managed networking |
| Works together | Optional CiliumNetworkPolicy authoring and Hubble Relay flows | — |
| Choose Cilium + Hubble when | You want a full CNI with policy enforcement and Hubble observability built in, and can make it your CNI |
Netra never modifies or pins over Cilium-owned BPF maps, so the two can share a cluster.

netractl install --namespace netra-system # Helm install: controller + node agent DaemonSet netractl status
Then open https:// :30870 and sign in. The dashboard sits behind a login screen — see Signing in (the nav bar and login screen carry the Zyvor mark).
Requires Linux with cgroup v2 and bpffs; practical baseline Linux 5.8+ (TCX 6.6+). Run netra-doctor first. Full steps, Helm values, Cilium/Hubble and CLI examples: [Install guide](docs/install.md).
Flows with pod and owner attribution, TCP health, DNS, TLS SNI and HTTP Host metadata, behavior baselines and drift. Live Hubble flows when Cilium is present. Capabilities →
TCP path diagnostics measure connect latency and transport pressure per workload, plus edge-observed handshake and RTT histograms that see NAT'd flows. Path → · Edge intel →
Congestion Map colors every layer of the Linux network stack by its worst finding, cluster-wide. One click jumps to a capture on the offending node. Kernel diagnostics →
Packet Capture streams a filtered, time-bounded capture live, color-coded by protocol, with a Wireshark-style layered decode and hex dump. Opt-in auto-capture persists PCAPs on critical findings. Capture →
A Congestion Map finding to a live, decoded, color-coded capture on the offending node:
Drop Explain answers "why was this dropped?" with kernel reasons and policy context. Drop diagnostics → · Drop info →
More: DNS, ICMP, behavior and rate insights.
Per-second metrics, zero config. Every node streams host, network stack, conntrack, cgroup, process-group, eBPF datapath and per-workload RED series to the controller, kept at 1 s for an hour, 1 min for two weeks and 1 h for a year. The Metrics page charts every context live, with an anomaly ribbon on each chart. Metrics →
