Detailed Description
A log record with trace correlation.
This represents a single log entry that can be correlated with a trace and span. By including trace_id and span_id, logs can be filtered and associated with specific operations in the distributed trace.
This structure follows the OpenTelemetry log data model.

◆ observed_timestamp
| std::optional<std::chrono::system_clock::time_point> observed_timestamp |
