Class ProfilerServiceClient (2.3.5) 

public class ProfilerServiceClient implements BackgroundResource

Service Description: Manage the collection of continuous profiling data provided by profiling agents running in the cloud or by an offline provider of profiling data.

General guidelines:

  • Profiles for a single deployment must be created in ascending time order.
  • Profiles can be created in either online or offline mode, see below.

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 (ProfilerServiceClient profilerServiceClient = ProfilerServiceClient.create()) {
   CreateProfileRequest request =
       CreateProfileRequest.newBuilder()
           .setParent("parent-995424086")
           .setDeployment(Deployment.newBuilder().build())
           .addAllProfileType(new ArrayList<ProfileType>())
           .build();
   Profile response = profilerServiceClient.createProfile(request);
 }

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

The surface of this class includes several types of Java methods for each of the API's methods:

  1. A "flattened" method. With this type of method, the fields of the request type have been converted into function parameters. It may be the case that not all fields are available as parameters, and not every API method will have a flattened method entry point.
  2. A "request object" method. This type of method only takes one parameter, a request object, which must be constructed before the call. Not every API method will have a request object method.
  3. A "callable" method. This type of method takes no parameters and returns 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 ProfilerServiceSettings 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
 ProfilerServiceSettings profilerServiceSettings =
     ProfilerServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 ProfilerServiceClient profilerServiceClient =
     ProfilerServiceClient.create(profilerServiceSettings);

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
 ProfilerServiceSettings profilerServiceSettings =
     ProfilerServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 ProfilerServiceClient profilerServiceClient =
     ProfilerServiceClient.create(profilerServiceSettings);

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
 ProfilerServiceSettings profilerServiceSettings =
     ProfilerServiceSettings.newBuilder()
         .setTransportChannelProvider(
             ProfilerServiceSettings.defaultHttpJsonTransportProviderBuilder().build())
         .build();
 ProfilerServiceClient profilerServiceClient =
     ProfilerServiceClient.create(profilerServiceSettings);

createProfile(CreateProfileRequest request)

public final Profile createProfile(CreateProfileRequest request)

CreateProfile creates a new profile resource in the online mode.

The server ensures that the new profiles are created at a constant rate per deployment, so the creation request may hang for some time until the next profile session is available.

The request may fail with ABORTED error if the creation is not available within ~1m, the response will indicate the duration of the backoff the client should take before attempting creating a profile again. The backoff duration is returned in google.rpc.RetryInfo extension on the response status. To a gRPC client, the extension will be return as a binary-serialized proto in the trailing metadata item named "google.rpc.retryinfo-bin".
