Exploring APM traces (OpenTelemetry spans)
PostHog captures distributed traces from OpenTelemetry. Each trace is a tree of spans representing a request's path through services.
Disambiguation: This skill is for APM / OpenTelemetry traces. Do not confuse with AI observability traces (agent/model $ai_* events) or logs (posthog:query-logs, posthog:logs-*).
Governed metric first
When the question asks for SLO burn, call posthog:metric-list before the APM tools and look for slo_explicit_burn_by_operation. Run an approved, non-drifted match with posthog:data-catalog-metric-run for the canonical headline. If the user also asks which operation drives the burn, answer the headline first, then use the aggregate and trace workflows below for a noncanonical breakdown. If no governed metric matches, say so and label the derived measure noncanonical.
