Types

type NoOpMetrics

type NoOpMetrics struct{}

NoOpMetrics is a no-op implementation

func (*NoOpMetrics) ObserveAPICall

func (m *NoOpMetrics) ObserveAPICall(call, status string, duration float64)

ObserveAPICall must be called on every API call made with the operation performed, the status code received and the duration of the call. This No-op implementation will perform no metrics accounting in return.

func (*NoOpMetrics) ObserveRateLimit

func (m *NoOpMetrics) ObserveRateLimit(operation string, duration time.Duration)

ObserveRateLimit must be called in case an API call was subject to rate limiting. This No-op implementation will perform no metrics accounting in return.

type PrometheusMetrics

type PrometheusMetrics struct {
	APIDuration *prometheus.HistogramVec
	RateLimit   *prometheus.HistogramVec
	// contains filtered or unexported fields
}

PrometheusMetrics is an implementation of Prometheus metrics for external API usage

func NewPrometheusMetrics

func NewPrometheusMetrics(namespace, subsystem string, registry metrics.RegisterGatherer) *PrometheusMetrics

NewPrometheusMetrics returns a new metrics tracking implementation to cover external API usage.

func (*PrometheusMetrics) ObserveAPICall

func (p *PrometheusMetrics) ObserveAPICall(operation, status string, duration float64)

ObserveAPICall must be called on every API call made with the operation performed, the status code received and the duration of the call

func (*PrometheusMetrics) ObserveRateLimit

func (p *PrometheusMetrics) ObserveRateLimit(operation string, delay time.Duration)

ObserveRateLimit must be called in case an API call was subject to rate limiting
