v4 · OpenTelemetry-native ingest

See everything
the moment
it happens.

Flux unifies event streams, metrics, and traces into one real-time query engine. Ingest millions of events per second, and ask anything of your production systems in single-digit milliseconds.

01 — One platform

Three signals, one query engine.

Stop stitching a logging tool to a metrics tool to a tracing tool. Flux correlates all three on a single timeline, so a spike in one is a click away from the cause in another.

// STREAMS

Live event streams

Structured logs and raw events, searchable the instant they land. Full-text and field filters over billions of rows without a sampling tax.

  • Sub-second index-to-searchable
  • Live tail with saved filters
  • Schema-on-read, no pre-defined columns
// METRICS

High-cardinality metrics

Every dimension, every tag, no rollups thrown away. Group by user, pod, or build SHA at read time and keep the resolution you paid to collect.

  • Unbounded label cardinality
  • PromQL & native FluxQL support
  • 1-second granularity, 13-month hot
request /checkout · 214ms

notify.enqueue · 28ms
// TRACES

Distributed traces

Follow one request across every service, queue, and database call. 100% of spans retained — no head-based sampling deciding what you get to debug.

  • Tail-based, 100% span retention
  • Flame graphs & service maps
  • One click from trace to its logs
02 — The engine

From wire to answer in one hop.

A columnar, log-structured engine built for write-heavy telemetry. No ETL, no downsampling job, no second system to keep in sync.

01

Ingest

OTLP, StatsD, Kafka, or raw HTTP land on the write path. Back-pressure-free, exactly-once, with per-tenant quotas.

→ write ack in ~2ms
02

Index

Events are columnar-encoded and indexed on ingest — every field searchable without a schema declared up front.

→ searchable in <800ms
03

Query

A vectorized engine scans compressed columns in parallel across the fleet. Dashboards, alerts, and ad-hoc — one path.

→ p99 42ms · p50 6ms
03 — Query anything

Ask in FluxQL. Answer before you blink.

04 — Fits your stack

05 — Enterprise-ready

Your telemetry is
evidence. We treat it that way.

Encrypted end to end, isolated per tenant, and audited independently. Deploy in our cloud, your VPC, or fully on-prem.

SOC 2 Type II
HIPAA
GDPR
ISO 27001
/01

AES-256 at rest, TLS 1.3 in flight

Customer-managed keys via KMS. Zero-trust internal service mesh with mTLS everywhere.

/02

Tenant isolation by default

Every query is scoped to your org at the storage layer — not a WHERE clause you have to trust.

/03

Immutable audit log

Every access, export, and config change is recorded and streamable to your own SIEM.

/04

Data residency & deletion

Pin storage to US, EU, or APAC. Field-level PII redaction and enforced TTLs on ingest.

06 — Pricing

Priced on events, not host count.

You never get billed for a machine sitting idle. Pay for what you ingest and query — and stop paying the instant traffic drops.
