// AUTO-GENERATED DOCUMENTATION AND CLASS.
/**
* Settings class to configure an instance of {@link MetricsServiceV2Stub}.
*
* The default instance has everything set to sensible defaults:
*
*
* - The default service address (logging.googleapis.com) and default port (443) are used.
*
- Credentials are acquired automatically through Application Default Credentials.
*
- Retries are configured for idempotent methods but not for non-idempotent methods.
*
*
* The builder of this class is recursive, so contained classes are themselves builders. When
* build() is called, the tree of builders is called to create the complete settings object.
*
*
For example, to set the total timeout of getLogMetric to 30 seconds:
*
*
{@code
* // 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
* MetricsServiceV2StubSettings.Builder metricsSettingsBuilder =
* MetricsServiceV2StubSettings.newBuilder();
* metricsSettingsBuilder
* .getLogMetricSettings()
* .setRetrySettings(
* metricsSettingsBuilder
* .getLogMetricSettings()
* .getRetrySettings()
* .toBuilder()
* .setTotalTimeout(Duration.ofSeconds(30))
* .build());
* MetricsServiceV2StubSettings metricsSettings = metricsSettingsBuilder.build();
