Reference documentation and code samples for the Cloud Logging V2 API class Google::Api::Distribution::Exemplar.
Exemplars are example points that may be used to annotate aggregated
distribution values. They are metadata that gives information about a
particular value added to a Distribution bucket, such as a trace ID that
was active when a value was added. They may contain further information,
such as a example values and timestamps, origin, etc.
