Types

type ConnMetrics

type ConnMetrics struct {
	Requests  *prometheus.CounterVec
	Responses *prometheus.CounterVec
}

ConnMetrics represents metrics of an individual conn or a collection of conns.

func (*ConnMetrics) Collect

func (cm *ConnMetrics) Collect(ch chan<- prometheus.Metric)

Collect implements prometheus.Collector.

func (*ConnMetrics) Describe

func (cm *ConnMetrics) Describe(ch chan<- *prometheus.Desc)

Describe implements prometheus.Collector.

func (*ConnMetrics) GetResponses

func (cm *ConnMetrics) GetResponses() map[string]map[string]map[string]commandMetrics

GetResponses returns a map with all response metrics:

opcode (e.g. "OP_MSG", "OP_QUERY") -> command (e.g. "find", "aggregate") -> argument that caused an error (e.g. "sort", "$count (stage)"; or "unknown") -> result (e.g. "NotImplemented", "InternalError"; or "ok") -> count.

type ListenerMetrics

type ListenerMetrics struct {
	Accepts     *prometheus.CounterVec
	Durations   *prometheus.HistogramVec
	ConnMetrics *ConnMetrics
}

ListenerMetrics represents listener metrics.

func NewListenerMetrics

func NewListenerMetrics() *ListenerMetrics

NewListenerMetrics creates new listener metrics.

func (*ListenerMetrics) Collect

func (lm *ListenerMetrics) Collect(ch chan<- prometheus.Metric)

Collect implements prometheus.Collector.

func (*ListenerMetrics) Describe

func (lm *ListenerMetrics) Describe(ch chan<- *prometheus.Desc)

Describe implements prometheus.Collector.
