Observability

The Problem

Observability tools are either expensive (Datadog), limited (free tiers), or require heavy instrumentation. And none of them know about your multi-tenant architecture — so filtering by customer requires custom work.

How Flux Handles It

Every Flux SDK operation is automatically instrumented:

• Auto-tracing: Auth checks, flag evaluations, billing queries — all traced
• Tenant-aware: Filter dashboards and alerts by organization
• Structured logs: Every Flux event is a structured, queryable log entry
• Custom metrics: Add your own metrics alongside Flux’s built-in ones
• OpenTelemetry export: Send data to your existing stack if you prefer

What Makes It Different

You don’t instrument Flux. Flux instruments itself. Every auth decision, every flag evaluation, every billing event — traced, logged, and queryable by tenant.

And because Flux owns the full stack, correlation is free. See the auth check that led to the flag evaluation that led to the billing query — in one trace.
