Age Gauge

See Age Gauge for the concept.

To Set() a specific time as the last success:

import (
    "github.com/Netflix/spectator-go/v2/spectator"
)

func main() {
    config, _ := spectator.NewConfig("udp", nil, nil)
    registry, _ := spectator.NewRegistry(config)

    registry.AgeGauge("time.sinceLastSuccess", nil).Set(1611081000)

    lastSuccess := registry.NewId("time.sinceLastSuccess", nil)
    registry.AgeGaugeWithId(lastSuccess).set(1611081000)
}

To set Now() as the last success:

import (
    "github.com/Netflix/spectator-go/v2/spectator"
)

func main() {
    config, _ := spectator.NewConfig("udp", nil, nil)
    registry, _ := spectator.NewRegistry(config)

    registry.AgeGauge("time.sinceLastSuccess", nil).Now()

    lastSuccess := registry.NewId("time.sinceLastSuccess", nil)
    registry.AgeGaugeWithId(lastSuccess).Now()
}
