Package flags defines command line flags that are shared by several jaeger components. They are defined in this shared location so that if several components are wired into a single binary (e.g. a local container of complete Jaeger backend) they can all share the flags.

func NewAdminServer

func NewAdminServer(hostPort string) *AdminServer

NewAdminServer creates a new admin server.

func (*AdminServer) AddFlags

func (s *AdminServer) AddFlags(flagSet *flag.FlagSet)

AddFlags registers CLI flags.

func (*AdminServer) Close

func (s *AdminServer) Close() error

Close stops the HTTP server

func (*AdminServer) HC

HC returns the reference to HeathCheck.

func (*AdminServer) Handle

func (*AdminServer) Serve

func (s *AdminServer) Serve() error

type Service

type Service struct {
	// AdminPort is the HTTP port number for admin server.
	AdminPort int

	// NoStorage indicates that storage-type CLI flag is not applicable
	NoStorage bool

	// Admin is the admin server that hosts the health check and metrics endpoints.
	Admin *AdminServer

	// Logger is initialized after parsing Viper flags like --log-level.
	Logger *zap.Logger

	// MetricsFactory is the root factory without a namespace.
	MetricsFactory metrics.Factory
