Convert Span Events to Log Records

Dash0 has introduced an opt-in feature enabling automatic conversion of span events into correlated log records during data ingestion. This addresses OpenTelemetry's deprecation of span events in favor of log records linked with trace context.

Background: OpenTelemetry has deprecated span events now that logs have become a stable, fully-implemented signal across SDKs.

How it works:

• Admins can enable this setting per-dataset in the Dataset settings page
• No instrumentation changes required — Dash0 automatically "fixes your telemetry" during ingestion
• Converted log records retain proper trace context
• A dash0.span_event.converted = true attribute tags converted records

Pricing impact: No change to overall costs. Span events and log records have always been priced equivalently — the bill simply shifts from "Spans and span events" to "Logs" based on conversion volume.

UI adjustments: The "Span events" column in the Tracing view is hidden when conversion is enabled, but can be restored via custom views.

Migration support: Dash0 published agent skills on GitHub to assist users who want to update their instrumentation directly rather than rely on automatic conversion.
