Functions

func GetGlobalMetricRegistry 

func GetGlobalMetricRegistry() prometheus.Registerer

GetGlobalMetricRegistry returns the global metric registry where auto-registering metrics are registered. The register to it should be only be done by its derived factories from NewFactory4Master, ... And the returned registry can be only used for unregister.

HTTPHandlerForMetricImpl return http.Handler for prometheus metric

func NewOnlyRegRegister 

func NewOnlyRegRegister(r prometheus.Registerer) prometheus.Registerer

func UnregisterWorkerMetrics 

func UnregisterWorkerMetrics(workerID frameModel.WorkerID)

UnregisterWorkerMetrics unregisters all metrics of workerID IF 'worker' is a job master, use job id as workerID IF 'worker' is a worker, use worker id as workerID
