Gauge

See Gauge for the concept.

Call Set() with a value:

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

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

    registry.Gauge("server.queueSize", nil).Set(10)

    queueSize := registry.NewId("server.queueSize", nil)
    registry.GaugeWithId(queueSize).Set(10)
}

Gauges will report the last set value for 15 minutes. This done so that updates to the values do not need to be collected on a tight 1-minute schedule to ensure that Atlas shows unbroken lines in graphs. A custom TTL may be configured for gauges. SpectatorD enforces a minimum TTL of 5 seconds.

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

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

    registry.GaugeWithTTL("server.queueSize", nil, 120 * time.Second).Set(10)

    queueSize := registry.NewId("server.queueSize", nil)
    registry.GaugeWithIdWithTTL(queueSize, 120 * time.Second).Set(10)
}
