## From the publisher

Workers Logs and OpenTelemetry spans for Durable Object requests include the Durable Object instance ID. Use $workers.durableObjectId to filter logs for a specific instance. Root and child spans include the same ID in cloudflare.durable\_object.id. Use these fields to isolate a specific instance and correlate its logs and traces. For more information, refer to Durable Objects metrics and analytics and Workers tracing spans and attributes.
