Functions

func PublishLastProcessTimestampMetrics

func PublishLastProcessTimestampMetrics(process string)

PublishLastProcessTimestampMetrics publishes the last timestamp of the provided process

func PublishPSCProcessMetrics

func PublishPSCProcessMetrics(process string, err error, start time.Time)

PublishLastProcessTimestampMetrics calculates and publishes the process latency

func RegisterMetrics

func RegisterMetrics()

Types

type PSCMetricsCollector

type PSCMetricsCollector interface {
	SetServiceAttachment(saKey string, state PSCState)
	DeleteServiceAttachment(saKey string)
	SetService(serviceKey string)
	DeleteService(serviceKey string)
}

PSCMetricsCollector is used to publish usage metrics

type PSCState

type PSCState struct {
	// InSuccess specifies if the ServiceAttachment was successfully created
	InSuccess bool
}

PSCState tracks service attachment and psc feautre usage
