Derived Types

Namespace

Google.Cloud.Monitoring.V3

Assembly

Type Description
string

DefaultScopes

public static IReadOnlyList<string> DefaultScopes { get; }

The default QueryService scopes.

Property Value
Type Description
IReadOnlyListstring
Remarks

The default QueryService scopes are:

GrpcClient

public virtual QueryService.QueryServiceClient GrpcClient { get; }

The underlying gRPC QueryService client

Property Value
Type Description
QueryServiceQueryServiceClient

ServiceMetadata

public static ServiceMetadata ServiceMetadata { get; }

The service metadata associated with this client type.

Methods

Create()

public static QueryServiceClient Create()

Synchronously creates a QueryServiceClient using the default credentials, endpoint and settings. To specify custom credentials or other settings, use QueryServiceClientBuilder.

Returns
Type Description
QueryServiceClient

The created QueryServiceClient.

CreateAsync(CancellationToken)

public static Task<QueryServiceClient> CreateAsync(CancellationToken cancellationToken = default)

Asynchronously creates a QueryServiceClient using the default credentials, endpoint and settings. To specify custom credentials or other settings, use QueryServiceClientBuilder.

Parameter
Name Description
cancellationToken CancellationToken

The CancellationToken to use while creating the client.
Returns
Type Description
TaskQueryServiceClient

The task representing the created QueryServiceClient.

QueryTimeSeries(QueryTimeSeriesRequest, CallSettings)

public virtual PagedEnumerable<QueryTimeSeriesResponse, TimeSeriesData> QueryTimeSeries(QueryTimeSeriesRequest request, CallSettings callSettings = null)

Queries time series using Monitoring Query Language.

Parameters
Name Description
request QueryTimeSeriesRequest

The request object containing all of the parameters for the API call.
callSettings CallSettings

If not null, applies overrides to this RPC call.
Returns
Type Description
PagedEnumerableQueryTimeSeriesResponseTimeSeriesData

A pageable sequence of TimeSeriesData resources.
Example 
// Create client
QueryServiceClient queryServiceClient = QueryServiceClient.Create();
// Initialize request argument(s)
QueryTimeSeriesRequest request = new QueryTimeSeriesRequest { Name = "", Query = "", };
// Make the request
PagedEnumerable<QueryTimeSeriesResponse, TimeSeriesData> response = queryServiceClient.QueryTimeSeries(request);

// Iterate over all response items, lazily performing RPCs as required
foreach (TimeSeriesData item in response)
{
    // Do something with each item
    Console.WriteLine(item);
}

// Or iterate over pages (of server-defined size), performing one RPC per page
foreach (QueryTimeSeriesResponse page in response.AsRawResponses())
{
    // Do something with each page of items
    Console.WriteLine("A page of results:");
    foreach (TimeSeriesData item in page)
    {
        // Do something with each item
        Console.WriteLine(item);
    }
}

// Or retrieve a single page of known size (unless it's the final page), performing as many RPCs as required
int pageSize = 10;
Page<TimeSeriesData> singlePage = response.ReadPage(pageSize);
// Do something with the page of items
Console.WriteLine($"A page of {pageSize} results (unless it's the final page):");
foreach (TimeSeriesData item in singlePage)
{
    // Do something with each item
    Console.WriteLine(item);
}
// Store the pageToken, for when the next page is required.
string nextPageToken = singlePage.NextPageToken;

QueryTimeSeriesAsync(QueryTimeSeriesRequest, CallSettings)

public virtual PagedAsyncEnumerable<QueryTimeSeriesResponse, TimeSeriesData> QueryTimeSeriesAsync(QueryTimeSeriesRequest request, CallSettings callSettings = null)

Queries time series using Monitoring Query Language.

Parameters
Name Description
request QueryTimeSeriesRequest

The request object containing all of the parameters for the API call.
callSettings CallSettings

If not null, applies overrides to this RPC call.
Returns
Type Description
PagedAsyncEnumerableQueryTimeSeriesResponseTimeSeriesData

A pageable asynchronous sequence of TimeSeriesData resources.
Example 
// Create client
QueryServiceClient queryServiceClient = await QueryServiceClient.CreateAsync();
// Initialize request argument(s)
QueryTimeSeriesRequest request = new QueryTimeSeriesRequest { Name = "", Query = "", };
// Make the request
PagedAsyncEnumerable<QueryTimeSeriesResponse, TimeSeriesData> response = queryServiceClient.QueryTimeSeriesAsync(request);

// Iterate over all response items, lazily performing RPCs as required
await response.ForEachAsync((TimeSeriesData item) =>
{
    // Do something with each item
    Console.WriteLine(item);
});

// Or iterate over pages (of server-defined size), performing one RPC per page
await response.AsRawResponses().ForEachAsync((QueryTimeSeriesResponse page) =>
{
    // Do something with each page of items
    Console.WriteLine("A page of results:");
    foreach (TimeSeriesData item in page)
    {
        // Do something with each item
        Console.WriteLine(item);
    }
});

// Or retrieve a single page of known size (unless it's the final page), performing as many RPCs as required
int pageSize = 10;
Page<TimeSeriesData> singlePage = await response.ReadPageAsync(pageSize);
// Do something with the page of items
Console.WriteLine($"A page of {pageSize} results (unless it's the final page):");
foreach (TimeSeriesData item in singlePage)
{
    // Do something with each item
    Console.WriteLine(item);
}
// Store the pageToken, for when the next page is required.
string nextPageToken = singlePage.NextPageToken;

ShutdownDefaultChannelsAsync()

public static Task ShutdownDefaultChannelsAsync()

Shuts down any channels automatically created by Create() and CreateAsync(CancellationToken). Channels which weren't automatically created are not affected.

Returns
Type Description
Task

A task representing the asynchronous shutdown operation.
Remarks

After calling this method, further calls to Create() and CreateAsync(CancellationToken) will create new channels, which could in turn be shut down by another call to this method.
