Netra

See every packet's story. Contain the bad ones. Let go automatically.

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

📖 [Read the full docs](https://zyvorai.github.io/zyvor-netra/) — quickstart, architecture, security model, and a product tour.

What's new

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.

Why Netra

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 vs Cilium + Hubble

	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.

See it live

Overview, the Firewall page's unified rules table and NetPol v2 allow-list, then a real in-browser VNC console connected to a running KubeVirt VM — captured against a live lab deployment, not a mockup:

*The Overview page.* More screens follow in Observe, Diagnose and Contain.

How it fits together

                        Browser / netractl

netrad serves HTTPS on :30870 by default. Hook model, visibility boundaries and the optional Cilium/Hubble integration: docs/architecture.md · Standalone eBPF.

Quickstart

make install                              # netractl → /usr/local/bin (or PREFIX=$HOME/.local)

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).

Observe

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 →

Diagnose

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.

Monitor

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 →

Anomaly detection on every dimension (unsupervised k-means, stdlib Go), plus "what changed here" ranking for any time range you drag across. Anomalies →
Metric alerts with Netdata-style rules and hysteresis, over 40 built in (CPU, memory, disk, interfaces, TCP, conntrack, workload RED, eBPF drops), sent through your existing Slack, webhook or PagerDuty channels. Alerts →
Evidence behind every chart: a spike links straight to the flows, drop reasons, TCP/DNS/HTTP boards and captures from the same window. Metrics and packets in one place.
App collectors for nginx, Apache, HAProxy, Redis, memcached, Envoy, CoreDNS, etcd and any Prom
