                ``identifier_case`` refers to which option in the identifier oneof is
                populated. For example, the filter ``identifier_case = "CUSTOM"`` would
                match all services with a value for the ``custom`` field. Valid options
                are "CUSTOM", "APP\_ENGINE", "CLOUD\_ENDPOINTS", and "CLUSTER\_ISTIO".
            page_size (int): The maximum number of resources contained in the

                resource, this parameter does not affect the return value. If page

                ``projects/{project_id}/services/{service_id}``.
            filter_ (str): A filter specifying what ``ServiceLevelObjective``\ s to return.
            page_size (int): The maximum number of resources contained in the
                underlying API response. If page streaming is performed per-
                resource, this parameter does not affect the return value. If page
                streaming is performed per-page, this determines the maximum number
                of resources in a page.
            view (~google.cloud.monitoring_v3.types.View): View of the ``ServiceLevelObjective``\ s to return. If ``DEFAULT``,
                return each ``ServiceLevelObjective`` as originally defined. If
                ``EXPLICIT`` and the ``ServiceLevelObjective`` is defined in terms of a

                spelling out how the SLI is computed.
            retry (Optional[google.api_core.retry.Retry]):  A retry object used

            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.api_core.page_iterator.PageIterator` instance.
            An iterable of :class:`~google.cloud.monitoring_v3.types.ServiceLevelObjective` instances.
