README

metermod

metermod exports metrics to the otel endpoint and flushes buffers before the application exits. By default it also collects Go runtime metrics.

	"github.com/go-srvc/mods/metermod"
	"github.com/go-srvc/mods/sigmod"
	"github.com/go-srvc/srvc"
)

func main() {
	srvc.RunAndExit(
		metermod.New(),
		sigmod.New(os.Interrupt),
		httpmod.New(
			httpmod.WithAddr(":8080"),
			httpmod.WithHandler(http.HandlerFunc(hello)),
		),
	)
}

func hello(w http.ResponseWriter, r *http.Request) {
	fmt.Fprint(w, "ok")
}
