io.opentelemetry.proto.profiles.v1experimental.Sample
All Implemented Interfaces:
com.google.protobuf.Message, com.google.protobuf.MessageLite, com.google.protobuf.MessageLiteOrBuilder, com.google.protobuf.MessageOrBuilder, SampleOrBuilder, Serializable
public final class Sample extends com.google.protobuf.GeneratedMessageV3 implements SampleOrBuilder
 Each Sample records values encountered in some program
 context. The program context is typically a stack trace, perhaps
 augmented with auxiliary information like the thread-id, some
 indicator of a higher level request being handled etc.
