Start with the failing request or workflow, use traces, logs, and metrics to establish what actually happened, then ask AI to compare plausible causes and suggest checks. Confirm the fix with a reproducible test or runtime observation.
How do I debug a problem that appears across multiple services?
Begin with the affected behavior, not a model-generated root cause. Record what failed, what should have happened, the approximate time window, the affected request or workflow, and the deployment or configuration context. This gives you a boundary for the investigation and helps distinguish the incident from nearby noise.
- Find the request’s distributed trace. A trace follows one request through services; its spans represent work along the path and show parent-child relationships. OpenTelemetry’s Observability Primer describes distributed tracing as a way to observe requests as they propagate through complex, distributed systems.
- Locate the first meaningful deviation. Follow the spans and look for an error, unexpected delay, missing operation, or change in the path. A downstream span associated with the failing request can narrow the search to a service or operation, but it does not by itself prove why that operation behaved as it did.
- Inspect related logs. Filter for the relevant service and time range. Logs are timestamped messages that can add detail about the operation represented in a trace.
- Compare relevant metrics. Metrics summarize system behavior. Check whether the symptom coincides with a broader change or appears limited to a particular request, service, or operation.
- Test a cause against the evidence. Reproduce the behavior if possible, or add a focused diagnostic or test that distinguishes the leading explanation from alternatives.
Traces, logs, and metrics answer different questions: traces connect work to a request, logs record events, and metrics summarize behavior. Correlating them helps move from a symptom to the operation and context that need closer inspection. OpenTelemetry is a vendor-neutral framework for instrumenting, generating, collecting, and exporting these signals. Its documentation index, modified August 29, 2025, states that the project is supported by more than 90 observability vendors; that is OpenTelemetry’s published figure, not an independently verified current market count.
Can AI find the root cause from logs and traces?
AI can help interpret evidence and generate testable explanations, but the available documentation does not establish that AI debugging is universally more accurate or faster, or provide a general success rate. Treat model output as a guide for investigation, not as confirmation that a root cause has been found.

Give the model a bounded evidence set: the relevant trace details, sanitized logs, the affected code path, the expected behavior, and the observed behavior. Ask it to separate observations from inferences, identify assumptions, offer competing explanations, and suggest concrete checks that could rule each one in or out. Avoid sending a large, unfiltered incident dump when a smaller time-bounded slice will answer the question.
For example, ask: “Given this request path and these sanitized error logs, list two plausible causes of the missing downstream operation. For each, state what evidence supports it, what you are assuming, and one check that would distinguish it from the other.” Then perform the checks yourself. A confident explanation is not a substitute for matching the proposed cause to runtime evidence or a reproducible test.
How do I debug an AI agent’s tool calls?
Trace the orchestration path, not just the final response. Capture the model call, tool invocation, retrieval step where applicable, and the result returned at each boundary. This makes it possible to compare an explanation of what the agent did with the recorded execution path.
GenAI telemetry conventions describe recording model identity and token counts, and can also include prompts, completions, tool calls, and results when content capture is explicitly enabled. Traces can help investigate problems such as failed API requests, execution loops, or latency bottlenecks in agent workflows. A trace may expose where the workflow diverged, but engineers still need to inspect the relevant inputs, outputs, and system behavior to establish the cause.

What should I instrument: automatic capture or application code?
Automatic instrumentation is a useful starting point where the language and libraries are supported. It can capture common library activity such as requests, database calls, and message-queue calls, often without source edits. Coverage and installation mechanisms vary by language, and automatic capture generally does not reveal application-specific decisions or internal state.
| Approach | Useful for | Limit to account for |
|---|---|---|
| Automatic or zero-code instrumentation | Common supported library operations, such as network requests, database calls, and queue activity | Language- and library-specific coverage; usually does not expose domain decisions or internal transitions |
| Code-based instrumentation | Application-specific decisions, business rules, and in-process transitions that explain why a path was taken | Requires changes to application code and careful selection of useful events and attributes |
Use code-level instrumentation when the automatically captured spans show where work occurred but not why the application chose that work or skipped another step. For agent systems, make sure context is carried across model, tool, and retrieval boundaries; otherwise, the execution path may be difficult to follow as one workflow.
How should I handle prompt and tool data in telemetry?
Content-level telemetry can make an AI workflow easier to diagnose, but prompts and tool results may contain sensitive information, and captured records may be large. OpenTelemetry’s 2026 walkthrough describes a Copilot example in which prompt-content capture is disabled by default; opting in can add prompts, system instructions, tool schemas, arguments, and results to telemetry attributes. Those details are specific to that example and should not be assumed to describe every tool or current configuration.
- Decide which fields are genuinely needed to diagnose the failure; capture model identity, token counts, and operation metadata where those answer the question without storing content.
- If content capture is necessary, define who may access it and how long it will be retained.
- Redact or omit sensitive content that is not needed, including secrets and personal or confidential information.
- Verify the current tool’s configuration and defaults before enabling capture; defaults and field names can differ across implementations.
How do I verify a proposed fix?
Choose a check that directly tests the observed failure condition. Reproduce the issue where feasible; otherwise, use a focused test, diagnostic, or interactive runtime debugger. Debug2Fix describes interactive debugging as complementary to static code analysis, not a replacement for it. After changing the system, test the original condition and nearby behavior that could be affected by the change.
Keep an incident record another engineer can follow: the relevant request or trace identifiers, the hypothesis, the check performed, and its outcome. That record should make clear which parts were observed and which were inferred.
How should teams compare debugging and observability options?
There is no independently established head-to-head ranking in the available documentation. Compare options against the requirements of your stack and workflow rather than assuming a vendor or AI feature is best:
- Coverage: supported languages, frameworks, services, databases, queues, and agent components.
- Context continuity: whether request or trace context follows work across services and tool boundaries.
- Signal correlation: how easily engineers can move between a trace and its related logs and metrics.
- Instrumentation depth: automatic library coverage and the ability to capture application-specific decisions.
- Privacy controls: content-capture defaults, selective capture, redaction, access management, and retention.
- Debugging interaction: whether developers can inspect live or recorded runtime state as well as static code.
- Portability and maturity: use of standard telemetry formats and the stability of conventions and integrations for the chosen stack.
OpenTelemetry’s documentation describes support from more than 90 observability vendors, but that published count does not establish equivalent coverage, privacy controls, or debugging quality across those options.
