/**
 * 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. Sample code to get started:
 *
 * ```
 * $loggingServiceV2Client = new LoggingServiceV2Client();
 * try {
 *     $formattedLogName = $loggingServiceV2Client->logName('[PROJECT]', '[LOG]');
 *     $loggingServiceV2Client->deleteLog($formattedLogName);
 * } finally {
 *     $loggingServiceV2Client->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.

     * However, those log entries can still be exported with
     * [LogSinks](https://cloud.google.com/logging/docs/api/tasks/exporting-logs).
     *
     * To improve throughput and to avoid exceeding the

     * you should try to include several log entries in this list,

     * @param array $optionalArgs {

     *
     *     @type string $logName
     *          Optional. A default log resource name that is assigned to all log entries
     *          in `entries` that do not specify a value for `log_name`:
     *
     *              "projects/[PROJECT_ID]/logs/[LOG_ID]"
     *              "organizations/[ORGANIZATION_ID]/logs/[LOG_ID]"

     *
     *          `[LOG_ID]` must be URL-encoded. For example:

     *              "organizations/1234567890/logs/cloudresourcemanager.googleapis.com%2Factivity"
     *
     *          The permission <code>logging.logEntries.create</code> is needed on each

     *          new log entries, whether the resource is specified in
     *          <code>logName</code> or in an individual log entry.
     *     @type MonitoredResource $resource
     *          Optional. A default monitored resource object that is assigned to all log
     *          entries in `entries` that do not specify a value for `resource`. Example:
     *
     *              { "type": "gce_instance",

     *          See [LogEntry][google.logging.v2.LogEntry].
     *     @type array $labels
     *          Optional. Default labels that are added to the `labels` field of all log
     *          entries in `entries`. If a log entry already has a label with the same key
     *          as a label in this parameter, then the log entry's label is not changed.
     *          See [LogEntry][google.logging.v2.LogEntry].
     *     @type bool $partialSuccess
     *          Optional. Whether valid entries should be written even if some other
     *          entries fail due to INVALID_ARGUMENT or PERMISSION_DENIED errors. If any
     *          entry is not written, then the response status is the error associated
     *          with one of the failed entries and the response includes error details
     *          keyed by the entries' zero-based index in the `entries.write` method.
     *     @type bool $dryRun
     *          Optional. If true, the request should expect normal response, but the
     *          entries won't be persisted nor exported. Useful for checking whether the
     *          logging API endpoints are working properly before sending valuable data.
