      # @return [Boolean] Indicates whether warnings are treated with the same
      # severity as errors. Default value: false .
      attr_accessor :consider_warning_as_error

      # @return [Integer] The maximum allowed percentage of unhealthy nodes
      # before reporting an error. For example, to allow 10% of nodes to be
      # unhealthy, this value would be 10.
      #
      # The percentage represents the maximum tolerated percentage of nodes
      # that can be unhealthy before the cluster is considered in error.
      # If the percentage is respected but there is at least one unhealthy
      # node, the health is evaluated as Warning.
      # The percentage is calculated by dividing the number of unhealthy nodes
      # over the total number of nodes in the cluster.
      # The computation rounds up to tolerate one failure on small numbers of
      # nodes. Default percentage is zero.
      #
      # In large clusters, some nodes will always be down or out for repairs,
      # so this percentage should be configured to tolerate that. Default
      # value: 0 .

      # @return [Integer] The maximum allowed percentage of unhealthy
      # applications before reporting an error. For example, to allow 10% of
      # applications to be unhealthy, this value would be 10.

      # The percentage represents the maximum tolerated percentage of
      # applications that can be unhealthy before the cluster is considered in
      # error.
      # If the percentage is respected but there is at least one unhealthy
      # application, the health is evaluated as Warning.
      # This is calculated by dividing the number of unhealthy applications
      # over the total number of application instances in the cluster,
      # excluding applications of application types that are included in the
      # ApplicationTypeHealthPolicyMap.
      # The computation rounds up to tolerate one failure on small numbers of
      # applications. Default percentage is zero. Default value: 0 .
      attr_accessor :max_percent_unhealthy_applications

      # @return [Array<ApplicationTypeHealthPolicyMapItem>] Defines a map with
      # max percentage unhealthy applications for specific application types.
      # Each entry specifies as key the application type name and as value an
      # integer that represents the MaxPercentUnhealthyApplications percentage
      # used to evaluate the applications of the specified application type.
      #
      # The application type health policy map can be used during cluster
      # health evaluation to describe special application types.
      # The application types included in the map are evaluated against the
      # percentage specified in the map, and not with the global
      # MaxPercentUnhealthyApplications defined in the cluster health policy.
      # The applications of application types specified in the map are not
      # counted against the global pool of applications.
      # For example, if some applications of a type are critical, the cluster
      # administrator can add an entry to the map for that application type
      # and assign it a value of 0% (that is, do not tolerate any failures).
      # All other applications can be evaluated with
      # MaxPercentUnhealthyApplications set to 20% to tolerate some failures
      # out of the thousands of application instances.
      # The application type health policy map is used only if the cluster
      # manifest enables application type health evaluation using the
      # configuration entry for
      # HealthManager/EnableApplicationTypeHealthEvaluation.
