A Trace is a collection of spans corresponding to a single operation or set of operations for an application. A span is an individual timed event which forms a node of the trace tree. A single trace may contain span(s) from multiple services.

credentials | 
        
          Optional[google.auth.credentials.Credentials]
          The authorization credentials to attach to requests. These credentials identify the application to the service; if none are specified, the client will attempt to ascertain the credentials from the environment.  |

          Union[str, 
          The transport to use. If set to None, a transport is chosen automatically.  |

          Designation of what errors, if any, should be retried.  |

          float
          The timeout for this request.  |

| Name | Description | 
request | 
        
          
          The request object. A span represents a single operation within a trace. Spans can be nested to form a trace tree. Often, a trace contains a root span that describes the end-to-end latency, and one or more subspans for its sub-operations. A trace can also contain multiple root spans, or none at all. Spans do not need to be contiguous—there may be gaps or overlaps between spans in a trace.  |
