    public final class Metric
    extends com.google.protobuf.GeneratedMessageV3
    implements MetricOrBuilder
     Defines a Metric which has one or more timeseries.  The following is a
     brief summary of the Metric data model.  For more details, see:
       https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/metrics/datamodel.md
     The data model and relation between entities is shown in the
     diagram below. Here, "DataPoint" is the term used to refer to any
     one of the specific data point value types, and "points" is the term used
     to refer to any one of the lists of points contained in the Metric.
     - Metric is composed of a metadata and data.
     - Metadata part contains a name, description, unit.
     - Data is one of the possible types (Sum, Gauge, Histogram, Summary).
     - DataPoint contains timestamps, attributes, and one of the possible value type
       fields.

     Each distinct type of DataPoint represents the output of a specific
     aggregation function, the result of applying the DataPoint's
     associated function of to one or more measurements.
     All DataPoint types have three common fields:
     - Attributes includes key-value pairs associated with the data point
     - TimeUnixNano is required, set to the end time of the aggregation
     - StartTimeUnixNano is optional, but strongly encouraged for DataPoints
       having an AggregationTemporality field, as discussed below.
     Both TimeUnixNano and StartTimeUnixNano values are expressed as
     UNIX Epoch time in nanoseconds since 00:00:00 UTC on 1 January 1970.
     # TimeUnixNano
     This field is required, having consistent interpretation across
     DataPoint types.  TimeUnixNano is the moment corresponding to when
     the data point's aggregate value was captured.
     Data points with the 0 value for TimeUnixNano SHOULD be rejected
     by consumers.
     # StartTimeUnixNano
     StartTimeUnixNano in general allows detecting when a sequence of
     observations is unbroken.  This field indicates to consumers the
     start time for points with cumulative and delta
     AggregationTemporality, and it should be included whenever possible
     to support correct rate calculation.  Although it may be omitted
     when the start time is truly unknown, setting StartTimeUnixNano is
     strongly encouraged.
