Package ratecounter provides a thread-safe rate-counter, for tracking counts
|
||
|
|
in an interval
|
||
|
|
|
||
|
|
Useful for implementing counters and stats of 'requests-per-second' (for example).
|
||
|
|
|
||
|
|
// We're recording marks-per-1second
|
||
|
|
counter := ratecounter.NewRateCounter(1 * time.Second)
|
||
|
|
|
||
|
|
// Record an event happening
|
||
|
|
counter.Mark()
|
||
|
|
|
||
|
|
// get the current requests-per-second
|
||
|
|
counter.Rate()
|
||
|
|
|
||
|
|
To record an average over a longer period, you can:
|
||
|
|
|
||
|
|
// Record requests-per-minute
|
||
|
|
counter := ratecounter.NewRateCounter(60 * time.Second)
|
||
|
|
|
||
|
|
// Calculate the average requests-per-second for the last minute
|
||
|
|
counter.Rate() / 60
|
||
|
