Unified signal stream
Metrics, distributed traces, structured logs, and real-user monitoring flow into one timeline. Correlate a spike in p99 latency with the deploy that caused it — in two clicks.
Ambient observability for distributed systems
Your whole system, in one light.
Lumen collects metrics, traces, logs, and user signals — correlates them in real time — and surfaces the exact insight your team needs before the pager fires.
- ✓No instrumentation tax
- ✓SOC 2 Type II
- ✓Sub-10s signal ingestion

Capabilities
One platform. Every signal unified.
Metrics, traces, logs, and real-user data correlated in real time — so the answer is already on screen when the question arrives.
live · <10s lag · embeddable
Ambient dashboards
Boards that update in near-real-time without a refresh. Surface the KPIs that matter on wall screens, in Slack, or embedded in your incident command channel.
adaptive · ML baseline · dedup
Intelligent alerting
Adaptive thresholds that learn your traffic shape — so Monday morning scale-ups stop paging the on-call team. Alert on anomaly, not on threshold guesses.
OTel · flame graph · service map
Deep trace explorer
Flame graphs and service maps rendered from OpenTelemetry spans. Drill from a slow HTTP endpoint down to the exact SQL statement adding 400ms.
auto-correlate · root cause · RCA
Incident timeline
Every alert, deploy, feature flag, and anomaly on a single timeline. Stop reconstructing incidents from Slack. The evidence is already correlated.

Teams that stopped reacting. Started seeing.
From four-person startups to infrastructure teams running at scale.
"We cut mean time to detect from 22 minutes to under 90 seconds. The correlated incident timeline alone justified the migration."
Yuki Tanaka
VP Engineering, Spectral
"Lumen replaced four separate tools — APM, logging, dashboards, and alerting. One bill, one UI, and the on-call rotation finally sleeps."
Amara Diallo
Head of Platform, Driftmark
"The adaptive alert baseline removed 80% of our false-positive pages in the first week. Engineers trust the pager again."
Marcus Heidegger
SRE Lead, Ironveil
