Constants

const (
	DomainStatsVersion = "v1"
)

For versioning of the virt-handler and -launcher communication, you need to increase the Version const when making changes, and make necessary changes in the cmd rpc implementation!

Types

type DomainStats

type DomainStats struct {
	// the following aren't really needed for stats, but it's practical to report
	// OTOH, the whole "Domain" is too much data to be unconditionally reported
	Name string

	// omitted from libvirt-go: Domain
	// omitted from libvirt-go: State
	Cpu *DomainStatsCPU
	// new, see below
	Memory *DomainStatsMemory

	Net   []DomainStatsNet
	Block []DomainStatsBlock
