Functions

func GetServiceMountedName

func GetServiceMountedName(namespaceRoot, serviceName string) (string, error)

GetServiceMountedName gets the full mounted name for the given service.

func ResolveAndProcessServiceName

func ResolveAndProcessServiceName(v23ctx *context.T, ctx *tool.Context, serviceName, serviceMountedName string) (map[string]naming.MountEntry, error)

ResolveAndProcessServiceName resolves the given service name and groups the result entries by their routing ids.

Types

type ServiceLocation

type ServiceLocation struct {
	Instance string
	Zone     string
}

func GetServiceLocation

func GetServiceLocation(v23ctx *context.T, ctx *tool.Context, me naming.MountEntry) (*ServiceLocation, error)

GetServiceLocation returns the given service's location (instance and zone). If the service is replicated, the instance name is the pod name.

To make it simpler and faster, we look up service's location in hard-coded "zone maps" for both non-replicated and replicated services.

type StatValue

type StatValue struct {
	Name  string
	Value interface{}
}

StatValue stores the name and the value returned from the GetStat function.

func GetStat

func GetStat(v23ctx *context.T, ctx *tool.Context, me naming.MountEntry, pattern string) ([]*StatValue, error)

GetStat gets the given stat using rpc.

func (*StatValue) GetFloat64Value

func (sv *StatValue) GetFloat64Value() (float64, error)

func (*StatValue) GetStringValue

func (sv *StatValue) GetStringValue() string
