Functions

func Prefixes

func Prefixes(topology []ID) []string

Prefixes return all application node prefixes for a given topology

Types

type HMNComponent

type HMNComponent struct {
	Source              string `json:"Source"`
	SourceRack          string `json:"SourceRack"`
	SourceLocation      string `json:"SourceLocation"`
	SourceParent        string `json:"SourceParent,omitempty"`
	SourceSubLocation   string `json:"SourceSubLocation,omitempty"`
	DestinationRack     string `json:"DestinationRack,omitempty"`
	DestinationLocation string `json:"DestinationLocation,omitempty"`
	DestinationPort     string `json:"DestinationPort,omitempty"`
}

HMNComponent is an individual component in the HMNConnections slice

type HMNConnections

type HMNConnections []HMNComponent

HMNConnections type is the go equivalent structure of hmn_connections.json

type ID

type ID struct {
	Architecture string   `json:"architecture"`
	CommonName   string   `json:"common_name"`
	ID           int      `json:"id"`
	Location     Location `json:"location"`
	Model        string   `json:"model"`
	Ports        []Port   `json:"ports"`
	Type         string   `json:"type"`
	Vendor       string   `json:"vendor"`
}

The ID type represents all of the information needed for each entry in the array

func FilterByType

func FilterByType(topology []ID, idType string) []ID

FilterByType loop over the topology and return all items found in a give type.

func (ID) GenerateNCNRoleSubrole

func (id ID) GenerateNCNRoleSubrole() (r string, sr string)

GenerateNCNRoleSubrole generates the appropriate role and subrole based on the ncn-* name

func (ID) GenerateSourceName

func (id ID) GenerateSourceName() string

GenerateSourceName crafts and prints the switch types that hmn_connections.json expects

func (ID) GenerateSwitchType

func (id ID) GenerateSwitchType() (st string)

GenerateSwitchType crafts and prints the switch types that switch_metadata.csv expects

func (ID) GenerateXname

func (id ID) GenerateXname() (xn string)

GenerateXname crafts and prints the xname of a give ID type in the SHCD

type Location

type Location struct {
	Elevation   string `json:"elevation"`
	Rack        string `json:"rack"`
	Parent      string `json:parent,omitempty`
	SubLocation string `json:sub_location,omitempty`
}

The Location type defines where the server physically exists in the datacenter.

type NCNMetadata

type NCNMetadata []NcnMacs

NCNMetadata type is the go equivalent structure of ncn_metadata.csv

type NcnMacs

type NcnMacs struct {
	Xname        string
	Role         string

	DestPort   int    `json:"destination_port"`
	DestSlot   string `json:"destination_slot"`
	Port       int    `json:"port"`
	Slot       string `json:"slot"`
	Speed      int    `json:"speed"`
}

The Port type defines where things are plugged in

type Shcd

type Shcd struct {
	Architecture string `json:"architecture"`
