span_id

Unique identifier of a span within a trace, an 8-byte array.

time_unix_nano

trace_id

Unique identifier of a trace, a 16-byte array.

otel_resource reference

The resource describes the entity that produced the log record. It contains a set of attributes (key-value pairs) that must have unique keys. For example, it can contain the hostname and the name of the cluster.

otel_scope reference

Describes the instrumentation scope that sent the message. It may contain simple key-value pairs (strings or integers), but also arbitrary nested objects, such as lists and arrays. It usually contains a name and a version field.
