Class HealthCheckServiceClient
- All Implemented Interfaces:
BackgroundResource,AutoCloseable
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 (HealthCheckServiceClient healthCheckServiceClient = HealthCheckServiceClient.create()) {
HealthCheckRequest request =
HealthCheckRequest.newBuilder()
.setCluster(ClusterName.of("[PROJECT]", "[LOCATION]", "[CLUSTER]").toString())
.build();
HealthCheckResponse response = healthCheckServiceClient.healthCheck(request);
}
Note: close() needs to be called on the HealthCheckServiceClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().
| Method | Description | Method Variants |
|---|---|---|
HealthCheck |
HealthCheck method checks the health status of the cluster. |
Request object method variants only take one parameter, a request object, which must be constructed before the call.
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.
|
ListLocations |
Lists information about the supported locations for this service. |
Request object method variants only take one parameter, a request object, which must be constructed before the call.
Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.
|
GetLocation |
Gets information about a location. |
Request object method variants only take one parameter, a request object, which must be constructed before the call.
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 HealthCheckServiceSettings 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
HealthCheckServiceSettings healthCheckServiceSettings =
HealthCheckServiceSettings.newBuilder()
.setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
.build();
HealthCheckServiceClient healthCheckServiceClient =
HealthCheckServiceClient.create(healthCheckServiceSettings);
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
HealthCheckServiceSettings healthCheckServiceSettings =
HealthCheckServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
HealthCheckServiceClient healthCheckServiceClient =
HealthCheckServiceClient.create(healthCheckServiceSettings);
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
HealthCheckServiceSettings healthCheckServiceSettings =
HealthCheckServiceSettings.newHttpJsonBuilder().build();
HealthCheckServiceClient healthCheckServiceClient =
HealthCheckServiceClient.create(healthCheckServiceSettings);
