Counter

See Counter for the concept.

Call Increment() when an event occurs:

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

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

    registry.Counter("server.numRequests", nil).Increment()

    numRequests := registry.NewId("server.numRequests", nil)
    registry.CounterWithId(numRequests).Increment()
}

You can also pass a value to Add(int64), or AddFloat(float64). This is useful when a collection of events happens together:

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

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

    registry.Counter("queue.itemsAdded", nil).Add(10)

    numRequests := registry.NewId("server.numRequests", nil)
    registry.CounterWithId(numRequests).Add(10)
}
