EverOS Observability

Use this sub-skill when a task asks about structured logs, request IDs, Prometheus metrics, OpenTelemetry/OTLP export, Langfuse traces/scores, privacy controls, or tracing demo workflows.

Read/run map

• Read observability for logging, /metrics, OTel configuration, trace lifecycle, and privacy settings.
• Read Langfuse for Langfuse-specific endpoint/key mapping, recall scores, demo/replay choices, and credential boundaries.
• Read troubleshooting for missing extras, rejected keys, no spans, score issues, content capture surprises, and noisy logs.
• Run trace_demo_driver.py against a running server. It defaults to health/config guidance; use --run-flow only when you intentionally want a tiny memory write/search to generate traces.

Key facts

• Structlog and stdlib logging are configured into one console-rendered format.
• Every request gets a request ID before handlers run.
• /metrics exposes the Prometheus registry.
• OpenTelemetry is optional and no-op-safe when disabled or the otel extra is absent.
• Langfuse integration uses native OTLP/HTTP plus optional Langfuse scores; EverOS does not require a Langfuse SDK.
• capture_content=false by default; set it true only after considering privacy.
