Types

type MetricContext

type MetricContext struct {
	Start      time.Time
	Attributes []string
	Metrics    *OpenstackMetrics
}

MetricContext indicates the context for OpenStack metrics.

func NewMetricContext

func NewMetricContext(resource string, request string) *MetricContext

NewMetricContext creates a new MetricContext.

func (*MetricContext) Observe

func (mc *MetricContext) Observe(om *OpenstackMetrics, err error) error

ObserveRequest records the request latency and counts the errors.

func (*MetricContext) ObserveReconcile

func (mc *MetricContext) ObserveReconcile(err error) error

ObserveReconcile records the request reconciliation duration

func (*MetricContext) ObserveRequest

func (mc *MetricContext) ObserveRequest(err error) error

ObserveRequest records the request latency and counts the errors.

type OpenstackMetrics

type OpenstackMetrics struct {
	Duration *metrics.HistogramVec
	Total    *metrics.CounterVec
	Errors   *metrics.CounterVec
}
