Class TraceServiceClient (2.45.0)

GitHub RepositoryProduct Reference

Service Description: 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. Spans for a single trace may span 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()) {
   String projectId = "projectId-894832108";
   String traceId = "traceId-1067401920";
   Trace response = traceServiceClient.getTrace(projectId, traceId);
 }
 

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().

Methods
Method Description Method Variants

ListTraces

Returns of a list of traces that match the specified filter conditions.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • listTraces(ListTracesRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • listTraces(String projectId)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • listTracesPagedCallable()

  • listTracesCallable()

GetTrace

Gets a single trace by its ID.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • getTrace(GetTraceRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • getTrace(String projectId, String traceId)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • getTraceCallable()

PatchTraces

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.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • patchTraces(String projectId, Traces traces)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

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);
