type PrometheusCollector

PrometheusCollector implements the metricCollector interface and exposes metrics for Prometheus.

type PrometheusCollector struct {
    // contains filtered or unexported fields
}

func NewPrometheusCollector

func NewPrometheusCollector(namespace string, reg prometheus.Registerer, durationBuckets []float64) *PrometheusCollector

NewPrometheusCollector creates a new PrometheusCollector. The namespace is used as the prefix for all metrics. If the namespace is empty, the prefix will be "hystrix". The durationBuckets are used for the totalDuration and runDuration metrics. If the durationBuckets are nil, the default buckets will be used.

func (*PrometheusCollector) Collector

func (pc *PrometheusCollector) Collector(name string) metricCollector.MetricCollector
