// AUTO-GENERATED DOCUMENTATION AND CLASS.
/**
* Service Description: The QueryService API is used to manage time series data in Cloud Monitoring.
* Time series data is a collection of data points that describes the time-varying values of a
* metric.
*
* 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:
*
*
{@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
* try (QueryServiceClient queryServiceClient = QueryServiceClient.create()) {
* QueryTimeSeriesRequest request =
* QueryTimeSeriesRequest.newBuilder()
* .setName("name3373707")
* .setQuery("query107944136")
* .setPageSize(883849137)
* .setPageToken("pageToken873572522")
* .build();
* for (TimeSeriesData element : queryServiceClient.queryTimeSeries(request).iterateAll()) {
* // doThingsWith(element);
* }
* }
* }
*
* Note: close() needs to be called on the QueryServiceClient 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
*
*
* QueryTimeSeries
Queries time series using Monitoring Query Language.
* Request object method variants only take one parameter, a request object, which must be constructed before the call.
*
* queryTimeSeries(QueryTimeSeriesRequest request)
*
* Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.
*
* queryTimeSeriesPagedCallable()
*
queryTimeSeriesCallable()
*
*
*
*
*
* 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 QueryServiceSettings to
* create(). For example:
*
*
To customize credentials:
*
*
{@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
* QueryServiceSettings queryServiceSettings =
* QueryServiceSettings.newBuilder()
* .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
* .build();
* QueryServiceClient queryServiceClient = QueryServiceClient.create(queryServiceSettings);
* }
*
* To customize the endpoint:
*
*
{@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
* QueryServiceSettings queryServiceSettings =
* QueryServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
* QueryServiceClient queryServiceClient = QueryServiceClient.create(queryServiceSettings);
* }
*
* Please refer to the GitHub repository's samples for more quickstart code snippets.
