func MetadataDecoder(raw json.RawMessage) (common.Getter, error)

MetadataDecoder implements a json message raw decoder

Types

type Address

type Address struct {
	Type     string `xml:"type,attr,omitempty"`

}

Address describes the XML coding of the pci address of an interface in libvirt

type Domain

type Domain struct {
	Interfaces  []Interface `xml:"devices>interface"`
	HostDevices []HostDev   `xml:"devices>hostdev"`
}

Domain is the subset of XML coding of a domain in libvirt

type DomainState

type DomainState = libvirt.DomainState

DomainState describes the state of a domain

type HostDev

type HostDev struct {
	Managed string `xml:"managed,attr,omitempty"`
	Mode    string `xml:"mode,attr,omitempty"`

}

Interface is XML coding of an interface in libvirt

func (*Interface) ProcessNode

func (itf *Interface) ProcessNode(g *graph.Graph, node *graph.Node) bool

}

Metadata describes the informations stored for a libvirt domain easyjson:json gendecoder

type Probe

type Probe struct {
	sync.Mutex
	// contains filtered or unexported fields
}

Probe is the libvirt probe

func NewProbe

func NewProbe(g *graph.Graph, uri string, root *graph.Node) *Probe

NewProbe creates a libvirt topology probe

func NewProbeFromConfig

func NewProbeFromConfig(g *graph.Graph, root *graph.Node) (*Probe, error)

NewProbeFromConfig initializes the probe

func (*Probe) Start

func (probe *Probe) Start()
