Types

type Metric

type Metric struct {
	MetricCollector prometheus.Collector
	ID              string
	Name            string
	Description     string
	Type            string
	Args            []string
}

Metric is a definition for the name, description, type, ID, and prometheus.Collector type (i.e. CounterVec, Summary, etc) of each metric

type Prometheus

type Prometheus struct {
	ReqCnt     *prometheus.CounterVec // 请求量指标
	SrvErrCnt  *prometheus.CounterVec // 服务异常指标
	DurSummary *prometheus.SummaryVec // 耗时指标

	MetricsList []*Metric
	MetricsPath string
	// contains filtered or unexported fields
}

Prometheus contains the metrics gathered by the instance and its path
