Observabilité de l'IA

It connects requests with retrieval, model calls, tools, and final outcomes. The aim is to investigate real behavior without treating a generated explanation as a reliable trace of internal computation.

Points clés à retenir

• Connect metrics, traces, and events.
• Measure task outcomes as well as uptime.
• Minimize and protect logged content.

Use complementary signals. Metrics show patterns such as latency, error rate, and resource use. Traces connect stages of a request. Logs describe events that help explain failures or decisions. Stable request and version identifiers make these signals more useful together. Add task-level measurements where possible. A technically successful model call can still return unsupported information or fail to complete the requested action. Track evidence coverage, validation failures, escalations, and verified outcomes alongside transport health. Protect sensitive content in telemetry. Recording every prompt and response can create a new private-data store. Collect the minimum needed for the diagnostic purpose, apply access and retention controls, and prefer redacted or aggregate information where it serves the same need. Make alerts actionable. Identify the owner, relevant threshold, diagnostic context, and recovery procedure. Avoid pages of noisy events that never lead to a decision. Test that a deliberately induced failure appears in the expected signal and that an operator can trace it to the affected release.

1. Imagine users reporting slow answers while model-generation time remains unchanged.
2. A request trace shows that document retrieval rose from 100 ms to 2 seconds after an index change.
3. Investigate that dependency and confirm recovery with fresh traces rather than replacing the model without evidence.

The invented timings demonstrate the value of connected measurements.
