Observability and request traces

Choose trace fields

A useful trace connects the application request to the work performed by the model infrastructure. Consider a request identifier, workload name, environment, policy version, route identifier, attempt number, status category, elapsed time, and available usage measurements. Use consistent field names across services. Include the stage that failed, such as validation, provider request, output parsing, or downstream processing.

Avoid storing credentials, full request bodies, or response content in routine telemetry. Metadata can still be sensitive when combined, so classify it, limit access, and set retention according to the organization’s policy. If payload sampling is needed for a defined evaluation or incident purpose, make it explicit, restricted, and time bounded.

Separate traces, metrics, and review data

Traces help follow an individual operation. Metrics summarize patterns across many operations, such as latency distributions, error rates, request volume, and fallback frequency. Quality review data supports evaluation of task outcomes and may require a separate collection process. Keeping these purposes distinct makes it easier to set appropriate access and retention for each dataset.

Label measurement sources. A count reported by a provider, an application estimate, and a billing record are different facts. Preserve the time window and aggregation method with a metric. Avoid adding high-cardinality identifiers to every dashboard dimension; use a trace lookup for individual requests and aggregate metrics for trends.

Respond to operational signals

Choose alerts that lead to an action. For example, a sustained provider timeout increase may prompt an availability check, while a rise in invalid structured output may require review of a prompt or route change. Set thresholds from the workload’s service expectations and normal patterns. Name the owner and runbook for each alert so an operator knows where to begin.

Record route and policy changes alongside operational events. When investigating an issue, compare affected workloads, environments, and time ranges. After resolution, add missing fields or improve a runbook only when the change answers a real diagnostic gap. More telemetry is not automatically more useful.

Privacy and retention review

Before enabling any content capture, identify why it is needed, who can access it, how long it remains, and how deletion or access requests are handled. Test redaction on representative examples and document the cases it may miss. Do not treat a scrubbed prompt as automatically anonymous. Apply the same care to exports, support bundles, and copied incident notes.

It makes no claim about a product’s logging implementation, provider data handling, or compliance status. Verify the behavior of each system and contract used in your environment.
