	go func() {
	http.Handle("/metrics", promhttp.Handler())
	listenOn := net.JoinHostPort(
	config.PrometheusConfig.ListenAddress,
	config.PrometheusConfig.ListenPort,
	)
	log.Infof("Serving metrics at %s", listenOn+"/metrics")
	log.Error(http.ListenAndServe(listenOn, nil))
	}()

Noticed within metrics code review should this run inside the group context so gets cancelled once the original context is cancelled.
