Export Go Module information to Prometheus.
Should work with any recent version of Go. Tested with Go versions starting 1.10.
go get github.com/povilasv/prommod
With modules:
GO111MODULE=on; go get github.com/povilasv/prommod
import (
"fmt"
"log"
"net/http"
"github.com/povilasv/prommod"
"github.com/prometheus/client_golang/prometheus"
"github.com/prometheus/client_golang/prometheus/promhttp"
)
func main() {
prometheus.Register(prommod.NewCollector("app_name"))
http.Handle("/metrics", promhttp.Handler())
log.Fatal(http.ListenAndServe(":8080", nil))
}
