A Go package that provides a simple time series implementation. This can be used to track the number of events that occur in a given time period.
import "github.com/blizzy78/gotimeseries"now := time.Now()
// construct a new time series that tracks 10 minutes
const buckets = 10
series := gotimeseries.New(time.Minute, buckets, now)
// ... time passes ...
now = now.Add(20 * time.Second)
// update the time series to account for the time that has passed
series.Update(now)
// track an event
series.Increase()
// ... time passes ...
now = now.Add(5*time.Minute + 40*time.Second)
// update the time series to account for the time that has passed
series.Update(now)
// track an event
series.Increase()
// ... time passes ...
now = now.Add(35 * time.Second)
// update the time series to account for the time that has passed
series.Update(now)
total := series.Total()
fmt.Printf("events in the last %dm: %d\n", buckets, total)
fmt.Printf("events/min: %.2f\n", float64(total)/float64(buckets))
// Output:
// events in the last 10m: 2
// events/min: 0.20This package is licensed under the MIT license.
