README

an opinionated wrapper around metric client libraries

imported from Grafana ffcc807ed34f853a8bc9600bcf7801547a5feb4f

supports:

• statsd (recommended!)
• dogstatsd

and later maybe more, like go-metrics

Why?

• make it easy to switch between libraries.
• some libraries just take in string arguments for gauge names etc, but it's nicer to have variables per object for robustness, especially when used in multiple places, and gives a central overview.
• allows you to set deleteGauges and deleteStats in your statsd servers ( a good thing for stateless servers), cause we will automatically keep a gauge sending.

Types

type Backend

type Backend interface {
	NewCount(key string) Count
	NewGauge(key string, val int64) Gauge
	NewMeter(key string, val int64) Meter
	NewTimer(key string, val time.Duration) Timer
}

type Count

type Count interface {
	Inc(val int64)
}

Count is a type that counts how many hits it's seen in each given interval and computes the rate per second it's not a long-running counter. values are explicit

type Gauge

type Gauge interface {
	Dec(val int64)
	Inc(val int64)
	Value(val int64)
}

gauge makes sure its value is explicit (i.e. for statsd, keep sending)

type Meter

type Meter interface {
	Value(val int64)
}

like a timer, but not just for timings

type Timer

type Timer interface {
	Value(val time.Duration)
}

computes stasticical summaries
