Class TraceServiceClient (2.45.0)

Service Description: Service for collecting and viewing traces and spans within a trace.

A trace is a collection of spans corresponding to a single operation or a set of operations in an application.

A span is an individual timed event which forms a node of the trace tree. A single trace can contain spans from multiple services.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (TraceServiceClient traceServiceClient = TraceServiceClient.create()) {
   ProjectName name = ProjectName.of("[PROJECT]");
   List<Span> spans = new ArrayList<>();
   traceServiceClient.batchWriteSpans(name, spans);
 }
 

Note: close() needs to be called on the TraceServiceClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

See the individual methods for example code.

Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parse method to extract the individual identifiers contained within names that are returned.

This class can be customized by passing in a custom instance of TraceServiceSettings to create(). For example:

To customize credentials:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 TraceServiceSettings traceServiceSettings =
     TraceServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 TraceServiceClient traceServiceClient = TraceServiceClient.create(traceServiceSettings);
 

To customize the endpoint:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 TraceServiceSettings traceServiceSettings =
     TraceServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 TraceServiceClient traceServiceClient = TraceServiceClient.create(traceServiceSettings);
 

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire:

 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 TraceServiceSettings traceServiceSettings = TraceServiceSettings.newHttpJsonBuilder().build();
 TraceServiceClient traceServiceClient = TraceServiceClient.create(traceServiceSettings);
 

Please refer to the GitHub repository's samples for more quickstart code snippets.

Constructs an instance of TraceServiceClient with default settings.

Constructs an instance of TraceServiceClient, using the given settings. The channels are created based on the settings passed in, or defaults for any settings that are not set.

Constructs an instance of TraceServiceClient, using the given stub for making calls. This is for advanced usage - prefer using create(TraceServiceSettings).

Constructs an instance of TraceServiceClient, using the given settings. This is protected so that it is easy to make a subclass, but otherwise, the static factory methods should be preferred.

Batch writes new spans to new or existing traces. You cannot update existing spans.

   BatchWriteSpansRequest request =
       BatchWriteSpansRequest.newBuilder()
           .setName(ProjectName.of("[PROJECT]").toString())
           .addAllSpans(new ArrayList<Span>())
