Signals

• Traces: span around the function operation and each critical provider call.
• Logs: concise structured OTLP log records for critical outcomes.
• Metrics: tenant-tagged counters/histograms for critical operations.
• LLM calls: capture

  llm.tokens.input

  /

  llm.tokens.output

  only when provider instrumentation is unavailable; tag explicit token counters with tenant, provider, model, use case, call site, and outcome. Do not calculate LLM cost in edge function code; Superlog estimates it centrally from provider/model/token data.
