Stackdriver Logging V2 Client - Class LoggingServiceV2Client (1.31.0)

Reference documentation and code samples for the Stackdriver Logging V2 Client class LoggingServiceV2Client.

Service Description: Service for ingesting and querying logs.

This class provides the ability to make remote calls to the backing service through method calls that map to API methods.

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.

Namespace

Google \ Cloud \ Logging \ V2 \ Client

Methods

__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 Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper 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 Google\ApiCore\CredentialsWrapper::build() .
`↳ 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 Google\ApiCore\Transport\TransportInterface 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 Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() 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.

deleteLog

Deletes all the log entries in a log for the _Default Log Bucket. The log reappears if it receives new entries. Log entries written shortly before the delete operation might not be deleted. Entries received after the delete operation with a timestamp before the operation will be deleted.

The async variant is Google\Cloud\Logging\V2\Client\LoggingServiceV2Client::deleteLogAsync() .

Parameters
Name	Description
`request`	`Google\Cloud\Logging\V2\DeleteLogRequest` A request to house fields associated with the call.
`callOptions`	`array` Optional.

writeLogEntries

Writes log entries to Logging. This API method is the only way to send log entries to Logging. This method is used, directly or indirectly, by the Logging agent (fluentd) and all logging libraries configured to use Logging.

A single request may contain log entries for a maximum of 1000 different resources (projects, organizations, billing accounts or folders)

The async variant is Google\Cloud\Logging\V2\Client\LoggingServiceV2Client::writeLogEntriesAsync() .

Parameters
Name	Description
`request`	`Google\Cloud\Logging\V2\WriteLogEntriesRequest` A request to house fields associated with the call.
`callOptions`	`array` Optional.
`↳ retrySettings`	`RetrySettings\|array` Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage.

`Google\Cloud\Logging\V2\WriteLogEntriesResponse`

Example

use Google\Cloud\Logging\V2\WriteLogEntriesRequest;

 * @param string $entriesLogName The resource name of the log to which this log entry belongs:
 *
 *                               "projects/[PROJECT_ID]/logs/[LOG_ID]"
 *                               "organizations/[ORGANIZATION_ID]/logs/[LOG_ID]"
 *                               "billingAccounts/[BILLING_ACCOUNT_ID]/logs/[LOG_ID]"
 *                               "folders/[FOLDER_ID]/logs/[LOG_ID]"
 *
 *                               A project number may be used in place of PROJECT_ID. The project number is
 *                               translated to its corresponding PROJECT_ID internally and the `log_name`
 *                               field will contain PROJECT_ID in queries and exports.
 *
 *                               `[LOG_ID]` must be URL-encoded within `log_name`. Example:
 *                               `"organizations/1234567890/logs/cloudresourcemanager.googleapis.com%2Factivity"`.
 *
 *                               `[LOG_ID]` must be less than 512 characters long and can only include the
 *                               following characters: upper and lower case alphanumeric characters,
 *                               forward-slash, underscore, hyphen, and period.
 *
 *                               For backward compatibility, if `log_name` begins with a forward-slash, such
 *                               as `/projects/...`, then the log entry is ingested as usual, but the
 *                               forward-slash is removed. Listing the log entry will not show the leading
 *                               slash and filtering for a log name with a leading slash will never return
 *                               any results.
