The log track payload format is defined in [MOQLOG]. Each MOQT Object contains a single JSON-formatted log entry. The log entry structure includes optional fields such as severity, timestamp, hostname, application name, process ID, message ID, and the log message itself. Additional structured data fields support distributed tracing integration with TraceID, SpanID, and InstrumentationScope aligned with OpenTelemetry specifications. Implementations MUST follow the object payload format specified in Section 4 of [MOQLOG].
