func (*Collector) Collect ¶

func (c *Collector) Collect(ch chan<- prometheus.Metric)

Collect prometheus metrics

func (*Collector) Describe ¶

func (c *Collector) Describe(ch chan<- *prometheus.Desc)

Describe prometheus metrics

func (*Collector) Remove ¶

func (c *Collector) Remove(t Statable)

Remove removes the provided cgroup by id from the collector

func (*Collector) RemoveAll ¶

func (c *Collector) RemoveAll()

RemoveAll statable items from the collector

type Statable ¶

type Statable interface {
	ID() string
	Namespace() string
	Stats(context.Context) (*types.Any, error)
}
