Functions

func RegisterPrometheusExporter

func RegisterPrometheusExporter(registry *prom.Registry) (http.Handler, error)

RegisterPrometheusExporter register a prometheus exporter to OpenCensus with a given prometheus metric registry. It will automatically add go runtime and process metrics using default prometheus collectors. The function return an http.handler that you can use to expose the prometheus endpoint.

func RegisterStackdriverExporter

func RegisterStackdriverExporter(projectID string) (sd *stackdriver.Exporter, err error)

RegisterStackdriverExporter register a Stackdriver exporter to OpenCensus. It will add Agones metrics into Stackdriver on Google Cloud.

func SetReportingPeriod

func SetReportingPeriod(prometheus, stackdriver bool)

SetReportingPeriod set appropriate reporting period which depends on exporters we are going to use

Types

type Controller

type Controller struct {
	// contains filtered or unexported fields
}

Controller is a metrics controller collecting Agones state metrics

func NewController

func NewController(
	kubeClient kubernetes.Interface,
	agonesClient versioned.Interface,
	kubeInformerFactory informers.SharedInformerFactory,
	agonesInformerFactory externalversions.SharedInformerFactory) *Controller

NewController returns a new metrics controller

func (*Controller) Run

func (c *Controller) Run(workers int, stop <-chan struct{}) error

Run the Metrics controller. Will block until stop is closed. Collect metrics via cache changes and parse the cache periodically to record resource counts.

type GameServerCount

type GameServerCount map[stablev1alpha1.GameServerState]map[string]int64

GameServerCount is the count of gameserver per current state and per fleet name
