          # The AlertPolicyService API is used to manage (list, create, delete,
          # edit) alert policies in Cloud Monitoring. An alerting policy is
          # a description of the conditions under which some aspect of your
          # system is considered to be "unhealthy" and the ways to notify
          # people or services about this state. In addition to using this API, alert
          # policies can also be managed through
          # [Cloud Monitoring](https://cloud.google.com/monitoring/docs/),
          # which can be reached by clicking the "Monitoring" tab in
          # [Cloud console](https://console.cloud.google.com/).

            # Configuration class for the AlertPolicyService API.
            #
            # This class represents the configuration for AlertPolicyService,
            # providing control over timeouts, retry behavior, logging, transport
            # parameters, and other low-level controls. Certain parameters can also be
            # applied individually to specific RPCs. See
            # {::Google::Cloud::Monitoring::V3::AlertPolicyService::Client::Configuration::Rpcs}
            # for a list of RPCs that can be configured independently.
            #
            # Configuration can be applied globally to all clients, or to a single client
            # on construction.
            #
            # @example
            #
            #   # Modify the global config, setting the timeout for
            #   # list_alert_policies to 20 seconds,
            #   # and all remaining timeouts to 10 seconds.
            #   ::Google::Cloud::Monitoring::V3::AlertPolicyService::Client.configure do |config|
            #     config.timeout = 10.0
            #     config.rpcs.list_alert_policies.timeout = 20.0
            #   end
            #
            #   # Apply the above configuration only to a new client.
            #   client = ::Google::Cloud::Monitoring::V3::AlertPolicyService::Client.new do |config|
            #     config.timeout = 10.0
