Functions

func GetCompletedRequests 

func GetCompletedRequests(entityType entity.Type, result RequestResult) int64

GetCompletedRequests gets the value of completed requests filtered by entity type and result.

func GetOngoingRequests 

func GetOngoingRequests(entityType entity.Type) int64

GetOngoingRequests gets the value for ongoing metrics filtered by entity type.

func GetRequestResultsNames 

func GetRequestResultsNames() map[RequestResult]string

GetRequestResultsNames returns a map containing all possible request result types and their names. This is also used to iterate through the possible results.

func InitAPIMetrics
