Stackdriver Monitoring V3 Client - Class QueryServiceClient (1.2.2)

Reference documentation and code samples for the Stackdriver Monitoring V3 Client class QueryServiceClient.

Service Description: The QueryService API is used to manage time series data in Stackdriver 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:

$queryServiceClient = new QueryServiceClient();
try {
    $name = 'name';
    $query = 'query';
    // Iterate over pages of elements
    $pagedResponse = $queryServiceClient->queryTimeSeries($name, $query);
    foreach ($pagedResponse->iteratePages() as $page) {
        foreach ($page as $element) {
            // doSomethingWith($element);
        }
    }
    // Alternatively:
    // Iterate through all elements
    $pagedResponse = $queryServiceClient->queryTimeSeries($name, $query);
    foreach ($pagedResponse->iterateAllElements() as $element) {
        // doSomethingWith($element);
    }
} finally {
    $queryServiceClient->close();
}

Methods

__construct

Constructor.

Parameters
NameDescription
options array

Optional. Options for configuring the service API wrapper.

↳ apiEndpoint string

The address of the API remote host. May optionally include the port, formatted as "

↳ credentials string|array|FetchAuthTokenInterface|CredentialsWrapper

The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage: In addition, this option can also accept a pre-constructed {@see} object or {@see} object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored.

↳ credentialsConfig array

Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see {@see} .

↳ disableRetries bool

Determines whether or not retries defined by the client configuration should be disabled. Defaults to false.

↳ clientConfig string|array

Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder.

↳ transport string|TransportInterface

The transport used for executing network requests. May be either the string rest or grpc. Defaults to grpc if gRPC support is detected on the system. Advanced usage: Additionally, it is possible to pass in an already instantiated {@see} object. Note that when this object is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored.

↳ transportConfig array

Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport. For example: $transportConfig = [ 'grpc' => [...], 'rest' => [...], ]; See the {@see} and {@see} methods for the supported options.

↳ clientCertSource callable

A callable which returns the client cert as a string. This can be used to provide a certificate and private key to the transport layer for mTLS.

queryTimeSeries

Queries time series using Monitoring Query Language. This method does not require a Workspace.

Parameters
NameDescription
name string

Required. The project on which to execute the request. The format is: projects/[PROJECT_ID_OR_NUMBER]

query string

Required. The query in the Monitoring Query Language format. The default time zone is in UTC.

optionalArgs array

Optional.

↳ pageSize int

The maximum number of resources contained in the underlying API response. The API may return fewer values in a page, even if there are additional values to be retrieved.

↳ pageToken string

A page token is used to specify a page of values to be returned. If no page token is specified (the default), the first page of values will be returned. Any page token used here must have been generated by a previous call to the API.

↳ retrySettings RetrySettings|array

Retry settings to use for this call. Can be a {@see} object, or an associative array of retry settings parameters. See the documentation on {@see} for example usage.
