Variables

var DefaultConfig = Config{
	Host:    "localhost",
	Port:    8080,
	Refresh: 5 * time.Second,
}

DefaultConfig contains default settings for the dashboard.

Functions

func Asset

func Asset(name string) ([]byte, error)

Asset loads and returns the asset for the given name. It returns an error if the asset could not be found or could not be loaded.

func AssetDigest

func AssetDigest(name string) ([sha256.Size]byte, error)

AssetDigest returns the digest of the file with the given name. It returns an error if the asset could not be found or the digest could not be loaded.

func AssetDir

func AssetDir(name string) ([]string, error)

AssetDir returns the file names below a certain directory embedded in the file by go-bindata. For example if you run go-bindata on data/... and data contains the following hierarchy:

data/
  foo.txt
  img/
    a.png
    b.png

then AssetDir("data") would return []string{"foo.txt", "img"}, AssetDir("data/img") would return []string{"a.png", "b.png"}, AssetDir("foo.txt") and AssetDir("notexist") would return an error, and AssetDir("") will return []string{"data"}.

func AssetInfo

func AssetInfo(name string) (os.FileInfo, error)

AssetInfo loads and returns the asset info for the given name. It returns an error if the asset could not be found or could not be loaded.

func AssetNames

func AssetNames() []string

AssetNames returns the names of the assets.

func AssetString

func AssetString(name string) (string, error)

AssetString returns the asset contents as a string (instead of a []byte).

func Digests

func Digests() (map[string][sha256.Size]byte, error)

Digests returns a map of all known files and their checksums.

func MustAsset

func MustAsset(name string) []byte

MustAsset is like Asset but panics when Asset would return an error. It simplifies safe initialization of global variables.

func MustAssetString

func MustAssetString(name string) string

MustAssetString is like AssetString but panics when Asset would return an error. It simplifies safe initialization of global variables.

func RestoreAsset

func RestoreAsset(dir, name string) error

RestoreAsset restores an asset under the given directory.

func RestoreAssets

func RestoreAssets(dir, name string) error

RestoreAssets restores an asset under the given directory recursively.

Types

type ChainMessage

type ChainMessage struct {
}

type ChartEntries

type ChartEntries []*ChartEntry

type ChartEntry

type ChartEntry struct {
	Time  time.Time `json:"time,omitempty"`
	Value float64   `json:"value,omitempty"`
}

type Config

type Config struct {
	// Host is the host interface on which to start the dashboard server. If this
	// field is empty, no dashboard will be started.
	Host string `toml:",omitempty"`

	// Port is the TCP port number on which to start the dashboard server. The
	// default zero value is/ valid and will pick a port number randomly (useful
	// for ephemeral nodes).
	Port int `toml:",omitempty"`

	// Refresh is the refresh rate of the data updates, the chartEntry will be collected this often.
	Refresh time.Duration `toml:",omitempty"`
}

Config contains the configuration parameters of the dashboard.

type Dashboard

type Dashboard struct {
	// contains filtered or unexported fields
}

Dashboard contains the dashboard internals.

func New

func New(config *Config, commit string) (*Dashboard, error)

New creates a new dashboard instance with the given configuration.

func (*Dashboard) APIs

func (db *Dashboard) APIs() []rpc.API

APIs is a meaningless implementation of node.Service.

func (*Dashboard) Protocols

func (db *Dashboard) Protocols() []p2p.Protocol

Protocols is a meaningless implementation of node.Service.

func (*Dashboard) Start

func (db *Dashboard) Start(server *p2p.Server) error

Start implements node.Service, starting the data collection thread and the listening server of the dashboard.

func (*Dashboard) Stop

func (db *Dashboard) Stop() error

Stop implements node.Service, stopping the data collection thread and the connection listener of the dashboard.
