Stackdriver Monitoring V3 Client - Class GroupServiceClient (1.2.2)

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

Service Description: The Group API lets you inspect and manage your groups.

A group is a named filter that is used to identify a collection of monitored resources. Groups are typically used to mirror the physical and/or logical topology of the environment. Because group membership is computed dynamically, monitored resources that are started in the future are automatically placed in matching groups. By using a group to name monitored resources in, for example, an alert policy, the target of that alert policy is updated automatically as monitored resources are added and removed from the infrastructure.

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:

$groupServiceClient = new Google\Cloud\Monitoring\V3\GroupServiceClient();
try {
    $name = 'name';
    $group = new Google\Cloud\Monitoring\V3\Group();
    $response = $groupServiceClient->createGroup($name, $group);
} finally {
    $groupServiceClient->close();
}

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 parseName method to extract the individual identifiers contained within formatted names that are returned by the API.

__construct

Constructor.

Parameters
Name	Description
`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.

`optionalArgs`	`array` Optional.
`↳ validateOnly`	`bool` If true, validate this request but do not create the group.
`↳ 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.
