Is there any way to stop UpdatePrometheusMetrics?

[nickylogan]

I'm trying to collect metrics of my service into prometheus using this rough implementation:

pc := prometheusmetrics.NewPrometheusProvider(someRegistry, someNameSpace, someSubSystem, prometheus.DefaultRegisterer, time.Second)
go pc.UpdatePrometheusMetrics()

http.Handle("/metrics", promhttp.Handler())
err := http.ListenAndServe(":8080", nil)
if err != nil {
	// stop UpdatePrometheusMetrics
}

Is there any way to stop UpdatePrometheusMetrics()? I don't want to leak an unnecessary goroutine if the endpoint is not even accessible.

Hey @nickylogan . So basically it's a goroutine. If you want to stop it you could do something like that

Hi @deathowl, thanks for replying. I don't think my question is understood quite correctly.

Internally, pc.UpdatePrometheusMetrics() runs an infinite ticker calling UpdatePrometheusMetricsOnce(). What I'm saying is, is there a method to stop the infinite ticker?

Ah thanks for the clarification. I'll add that tonight
