Gets a logs-based metric.

        Example:
            >>> from google.cloud import logging_v2
            >>>
            >>> client = logging_v2.MetricsServiceV2Client()

            >>> metric_name = client.metric_path('[PROJECT]', '[METRIC]')
            >>>
            >>> response = client.get_log_metric(metric_name)

        Args:
            metric_name (str): The resource name of the desired metric:

                ::

                     "projects/[PROJECT_ID]/metrics/[METRIC_ID]"
            retry (Optional[google.api_core.retry.Retry]):  A retry object used
                to retry requests. If ``None`` is specified, requests will not
                be retried.
            timeout (Optional[float]): The amount of time, in seconds, to wait
                for the request to complete. Note that if ``retry`` is
                specified, the timeout applies to each individual attempt.
            metadata (Optional[Sequence[Tuple[str, str]]]): Additional metadata
                that is provided to the method.

        Returns:
            A :class:`~google.cloud.logging_v2.types.LogMetric` instance.

        Raises:
            google.api_core.exceptions.GoogleAPICallError: If the request
                    failed for any reason.
            google.api_core.exceptions.RetryError: If the request failed due
                    to a retryable error and retry attempts failed.
            ValueError: If the parameters are invalid.
