// if you use middleware, AutoTrigger is usually false
AutoTrigger() bool
Metrics() []*Metric
// Interval the interval of the Update() to collect metrics
Interval() time.Duration
Middleware(c *gin.Context)
// contains filtered or unexported methods
}
Collector can collect many metrics by one Update()
