Types

type Host

type Host string

type Info

type Info struct {
	// Public IP of the host. Nodes running in cloud usually
	// get assigned a public and an internal IP.
	PublicIP string
	// Internal IP of the host. This is the IP that heapster will
	// use to communicate with the host sinc Public IP access is usually
	// restricted behind firewalls.
	InternalIP string
	// An optional ID assigned to nodes by either the cloud provider or user.
	ExternalID string
	// Cpu capacity of node in millicores.
	CpuCapacity uint64
	// Memory capacity of node in bytes.
	MemCapacity uint64
}

type Node

type Node struct {
	// Hostname
	Name string
}

type NodeList

type NodeList struct {
	Items map[Host]Info
}

NodeList contains the nodes that an instance of heapster is required to monitor.

type NodesApi

type NodesApi interface {
	// Returns a list of nodes that needs to be monitores or error on failure.
	List() (*NodeList, error)

	// Returns a string that contains internal debug information.
	DebugInfo() string
}
