Types

type Collector

type Collector interface {
	Destroy()
	UpdateStats(*info.ContainerStats) error
}

Collector can update ContainerStats by adding more metrics.

type Manager

type Manager interface {
	Destroy()
	GetCollector(deviceCgroup string) (Collector, error)
}

This is supposed to store global state about an cAdvisor metrics collector. cAdvisor manager will call Destroy() when it stops. For each container detected by the cAdvisor manager, it will call GetCollector() with the devices cgroup path for that container. GetCollector() is supposed to return an object that can update accelerator stats for that container.
