Workflow Creation metrics

Functions

func NewWorkflowServiceWrapper

func NewWorkflowServiceWrapper(service workflowserviceclient.Interface, scope tally.Scope) workflowserviceclient.Interface

NewWorkflowServiceWrapper creates a new wrapper to WorkflowService that will emit metrics for each service call.

func WrapScope

func WrapScope(isReplay *bool, scope tally.Scope, clock Clock) tally.Scope

WrapScope wraps a scope and skip recording metrics when isReplay is true. This is designed to be used by only by workflowEnvironmentImpl so we suppress metrics while replaying history events. Parameter isReplay is a pointer to workflowEnvironmentImpl.isReplay which will be updated when replaying history events.

Types

type Clock

type Clock interface {
	Now() time.Time
}

Clock defines interface used as time source
