Package provides simple uniform interface for counters.
It is compatible with expvar package, that is also commonly used for monitoring.
Fork notes: this fork removes gauges and histograms and slightly changes the behaviour of frame roll logic.
// Create new metric. All metrics may take time frames if you want them to keep
// history. If no time frames are given the metric only keeps track of a single
// current value.
c := metric.NewCounter(15 * time.Minute, 10 * time.Second) // 15 minutes of history with 10 second precision
// Increment counter
c.Add(1)
// Return JSON with all recorded counter values
c.String() // Or json.Marshal(c)Metrics are thread-safe and can be updated from background goroutines.
