Features
Nine probe types today, a full platform around them, and an honest roadmap for the rest.
Probe types
Available nowHTTP
Availability + full httptrace timing breakdown, status codes, redirects, TLS expiry.
TCP
Basic port / connectivity checks.
DNS
Resolution against arbitrary servers with DNSSEC and full record-type coverage.
Path / ICMP
Ping (unprivileged) latency/loss and raw-socket hop-by-hop traceroute.
Agent-to-agent
Node-to-node loss & latency; the building block of auto-mesh.
BGP
Receive-only session monitoring: FSM state, uptime, RIB-in counts, UPDATE tally.
Browser page-load
Headless Chromium: Navigation Timing phases, paint metrics, transfer cost.
Transactions
Closed step-list multi-step browser flows (navigate / click / fill / wait / assert).
Voice / SIP
Single-ended OPTIONS/REGISTER with digest auth. Signaling health only.
Platform
Available nowAlerting
Threshold + N-of-M with mandatory hysteresis and a live alert SSE stream.
Event correlation
Groups simultaneous incidents by shared target / hop / ASN into incident groups.
Dashboards
Ordered widget boards; soft-referenced test tiles in a responsive grid.
Shareable snapshots
Frozen, token-gated incident windows viewable without an account.
Auto-mesh
Declare a mesh; FourEyes keeps one a2a test per ordered pair wired automatically.
GitOps (foureyesctl)
Declare tests/alerts/dashboards as YAML; apply / diff / export.
Prometheus /metrics
Per-test series with dynamic labels on the standard pull endpoint.
OTLP metrics & traces
Push the same metrics, plus per-probe-round spans, to any OTel collector.
Signed self-update
ed25519-verified, atomic node updates with jittered, gradual rollouts.
Storage backends
SQLite (relational + time-series, pure Go default) or DuckDB (CGO opt-in).
On the roadmap
Not yet shippedFourEyes is upfront about what isn't built yet. These items are planned — see the roadmap for detail.
- ○ PostgreSQL + ClickHouse scale backends
- ○ External alert routing (email / Slack / PagerDuty / Alertmanager / webhook)
- ○ One-line installers (curl | sh, PowerShell, apt / dnf packages)
- ○ Multi-tenant RBAC (a default-org scope is the current stand-in)
- ○ Full RTP / E-model MOS voice validation (needs a far-end peer)
- ○ BGP per-prefix route-event log, RIB dump, and AS-path topology UI
