Class TraceServiceClient (1.8.0)

TraceServiceClient(*, credentials: Optional[google.auth.credentials.Credentials] = None, transport: Optional[Union[str, google.cloud.trace_v2.services.trace_service.transports.base.TraceServiceTransport]] = None, client_options: Optional[Union[google.api_core.client_options.ClientOptions, dict]] = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

This file describes an API for collecting and viewing traces and spans within a trace. 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.

Properties

transport

Returns the transport used by the client instance.

Returns

Type	Description
`TraceServiceTransport`	The transport used by the client instance.

Methods

TraceServiceClient

TraceServiceClient(*, credentials: Optional[google.auth.credentials.Credentials] = None, transport: Optional[Union[str, google.cloud.trace_v2.services.trace_service.transports.base.TraceServiceTransport]] = None, client_options: Optional[Union[google.api_core.client_options.ClientOptions, dict]] = None, client_info: google.api_core.gapic_v1.client_info.ClientInfo = <google.api_core.gapic_v1.client_info.ClientInfo object>)

Instantiates the trace service client.

Parameters

Name	Description
`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.
`transport`	`Union[str, TraceServiceTransport]` The transport to use. If set to None, a transport is chosen automatically.
`client_options`	`Optional[Union[google.api_core.client_options.ClientOptions, dict]]` Custom options for the client. It won't take effect if a `transport` instance is provided. (1) The `api_endpoint` property can be used to override the default endpoint provided by the client. GOOGLE_API_USE_MTLS_ENDPOINT environment variable can also be used to override the endpoint: "always" (always use the default mTLS endpoint), "never" (always use the default regular endpoint) and "auto" (auto switch to the default mTLS endpoint if client certificate is present, this is the default value). However, the `api_endpoint` property takes precedence if provided. (2) If GOOGLE_API_USE_CLIENT_CERTIFICATE environment variable is "true", then the `client_cert_source` property can be used to provide client certificate for mutual TLS transport. If not provided, the default SSL client certificate will be used if present. If GOOGLE_API_USE_CLIENT_CERTIFICATE is "false" or not set, no client certificate will be used.
`client_info`	`google.api_core.gapic_v1.client_info.ClientInfo` The client info used to send a user-agent string along with API requests. If `None`, then default info will be used. Generally, you only need to set this if you're developing your own client library.

Exceptions

Type	Description
`google.auth.exceptions.MutualTLSChannelError`	If mutual TLS transport creation failed for any reason.

exit

__exit__(type, value, traceback)

Releases underlying transport's resources.

batch_write_spans

batch_write_spans(request: Optional[Union[google.cloud.trace_v2.types.tracing.BatchWriteSpansRequest, dict]] = None, *, name: Optional[str] = None, spans: Optional[MutableSequence[google.cloud.trace_v2.types.trace.Span]] = None, retry: Union[google.api_core.retry.Retry, google.api_core.gapic_v1.method._MethodDefault] = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: Union[float, object] = <_MethodDefault._DEFAULT_VALUE: <object object>>, metadata: Sequence[Tuple[str, str]] = ())

Sends new spans to new or existing traces. You cannot update existing spans.

Name	Description
`request`	`Union[google.cloud.trace_v2.types.BatchWriteSpansRequest, dict]` The request object. The request message for the `BatchWriteSpans` method.
`name`	`str` Required. The name of the project where the spans belong. The format is `projects/[PROJECT_ID]`. This corresponds to the `name` field on the `request` instance; if `request` is provided, this should not be set.
`spans`	`MutableSequence[google.cloud.trace_v2.types.Span]` Required. A list of new spans. The span names must not match existing spans, or the results are undefined. This corresponds to the `spans` field on the `request` instance; if `request` is provided, this should not be set.

Parameters

Name	Description
`request`	`Union[google.cloud.trace_v2.types.Span, dict]` 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.
`retry`	`google.api_core.retry.Retry` Designation of what errors, if any, should be retried.
`timeout`	`float` The timeout for this request.
`metadata`	`Sequence[Tuple[str, str]]` Strings which should be sent along with the request as metadata.

Returns
