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:

 try (ProfilerServiceClient profilerServiceClient = ProfilerServiceClient.create()) {
   CreateProfileRequest request =
       CreateProfileRequest.newBuilder()
           .setParent("parent-995424086")
           .setDeployment(Deployment.newBuilder().build())
           .addAllProfileType(new ArrayList

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:

 ProfilerServiceSettings profilerServiceSettings =
     ProfilerServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 ProfilerServiceClient profilerServiceClient =
     ProfilerServiceClient.create(profilerServiceSettings);
 

To customize the endpoint:

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

Static Methods

create()

public static final ProfilerServiceClient create()

Constructs an instance of ProfilerServiceClient with default settings.

Returns

Type	Description
ProfilerServiceClient

Exceptions

Type	Description
IOException

create(ProfilerServiceSettings settings)

public static final ProfilerServiceClient create(ProfilerServiceSettings settings)

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

create(ProfilerServiceStub stub)

public static final ProfilerServiceClient create(ProfilerServiceStub stub)

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

stub	ProfilerServiceStub

Returns

Type	Description
ProfilerServiceClient

Constructors

ProfilerServiceClient(ProfilerServiceSettings settings)

protected ProfilerServiceClient(ProfilerServiceSettings settings)

Constructs an instance of ProfilerServiceClient, 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.

Parameter

close()

public final void close()

createOfflineProfile(CreateOfflineProfileRequest request)

public final Profile createOfflineProfile(CreateOfflineProfileRequest request)

CreateOfflineProfile creates a new profile resource in the offline mode. The client provides the profile to create along with the profile bytes, the server records it.

Sample code:

 try (ProfilerServiceClient profilerServiceClient = ProfilerServiceClient.create()) {
   CreateOfflineProfileRequest request =
       CreateOfflineProfileRequest.newBuilder()
           .setParent("parent-995424086")
           .setProfile(Profile.newBuilder().build())
           .build();
   Profile response = profilerServiceClient.createOfflineProfile(request);
 }
 

Parameter

Name	Description
request	CreateOfflineProfileRequest The request object containing all of the parameters for the API call.

Returns

Type	Description
Profile

createOfflineProfileCallable()

public final UnaryCallable<CreateOfflineProfileRequest,Profile> createOfflineProfileCallable()

CreateOfflineProfile creates a new profile resource in the offline mode. The client provides the profile to create along with the profile bytes, the server records it.

Sample code:

 try (ProfilerServiceClient profilerServiceClient = ProfilerServiceClient.create()) {
   CreateOfflineProfileRequest request =
       CreateOfflineProfileRequest.newBuilder()
           .setParent("parent-995424086")
           .setProfile(Profile.newBuilder().build())
           .build();
   ApiFuture<Profile> future =
       profilerServiceClient.createOfflineProfileCallable().futureCall(request);
   // Do something.
   Profile response = future.get();
 }
 

Returns

Type	Description
UnaryCallable<CreateOfflineProfileRequest,Profile>

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".

Sample code:

 try (ProfilerServiceClient profilerServiceClient = ProfilerServiceClient.create()) {
   CreateProfileRequest request =
       CreateProfileRequest.newBuilder()
           .setParent("parent-995424086")
           .setDeployment(Deployment.newBuilder().build())
           .addAllProfileType(new ArrayList

Parameter

Name	Description
request	CreateProfileRequest The request object containing all of the parameters for the API call.

Returns

Type	Description
