Types

type Entry

type Entry interface {
	// WithFields allows the caller to set metric metadata. Once an entry object is
	// created (typically using a meaningful metrics name), its properties can be
	// manipulated using WithFields. Example:
	//
	// m := m.WithFields(map[string]interface{"timestamp": time.Now()})
	WithFields(f map[string]interface{}) Entry
	// WithCount allows the caller to set metric counts. This is useful for determining
	// if a particular operation has occurred or not. Example:
	//
	// item, ok := lookup(key)
	// if ok {
	//   lookupSuccessMetric = lookupSuccessMetric.WithCount(1)
	//   // Use item
	// } else {
	//   lookupSuccessMetric = lookupSuccessMetric.WithCount(0))
	// }
	WithCount(count int) Entry
	// WithGauge allows the caller to associate a specific value to the metric. This is useful
	// for reporting numerical values related to any operation, for instance the data transfer
	// rate for an image pull operation.
	WithGauge(value interface{}) Entry
	// Done makes a metric operation as complete. It records the end time of the operation and
	// flushes the metric to a persistent store.
	Done(err error)
}

Entry specifies methods that need to be implemented by a metrics entry object.

type EntryFactory

type EntryFactory interface {
	New(op string) Entry
	Flush()
}

EntryFactory specifies the factory interface for creating new Metric Entry objects.

func NewNopEntryFactory

func NewNopEntryFactory() EntryFactory

NewNopEntryFactory creates a metric log entry factory that doesn't log any metrics.
