Returns the traces Resource.

Sends new traces to Stackdriver Trace or updates existing traces. If the ID

### Method Details

`patchTraces(projectId, body=None, x__xgafv=None)`

    Sends new traces to Stackdriver Trace or updates existing traces. If the ID
    of a trace that you send matches that of an existing trace, any fields
    in the existing trace and its spans are overwritten by the provided values,
    and any new fields provided are merged with the existing trace data. If the
    ID does not match, a new trace is created.
    In this case, writing traces is not considered an active developer
    method since traces are machine generated.

    Args:
      projectId: string, Required. ID of the Cloud project where the trace data is stored. (required)
      body: object, The request body.
        The object takes the form of:

    { # List of new or updated traces.
        "traces": [ # List of traces.
          { # A trace describes how long it takes for an application to perform an
              # operation. It consists of a set of spans, each of which represent a single
              # timed event within the operation.
            "projectId": "A String", # Project ID of the Cloud project where the trace data is stored.
            "spans": [ # Collection of spans in the trace.
              { # A span represents a single timed event within a trace. Spans can be nested
                  # and form a trace tree. Often, a trace contains a root span that describes the
                  # end-to-end latency of an operation and, optionally, one or more subspans for
                  # its suboperations. Spans do not need to be contiguous. There may be gaps
                  # between spans in a trace.

    Returns:
      An object of the form:

        { # A generic empty message that you can re-use to avoid defining duplicated
          # empty messages in your APIs. A typical example is to use it as the request
          # or the response type of an API method. For instance:
          #
          #     service Foo {
          #       rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty);
          #     }
          #
          # The JSON representation for `Empty` is empty JSON object `{}`.
