`kind` string	`MetricListOptions`
`labelSelector` `string`	A selector to restrict the list of returned objects by their labels. Defaults to everything.

`MetricValue`

Appears in:

MetricValueList

MetricValue is the metric value for some object

Field	Description
`apiVersion` string	`custom.metrics.k8s.io/v1beta2`
`kind` string	`MetricValue`
`describedObject` [Required] `core/v1.ObjectReference`	a reference to the described object
`metric` [Required] `MetricIdentifier`	No description provided.
`timestamp` [Required] `meta/v1.Time`	indicates the time at which the metrics were produced
`windowSeconds` [Required] `int64`	indicates the window ([Timestamp-Window, Timestamp]) from which these metrics were calculated, when returning rate metrics calculated from cumulative metrics (or zero for non-calculated instantaneous metrics).
`value` [Required] `k8s.io/apimachinery/pkg/api/resource.Quantity`	the value of the metric for this

`MetricValueList`

MetricValueList is a list of values for a given metric for some set of objects

Field	Description
