I can see Prometheus list the pods using service discovery but it can’t scrape metrics from each pod, it says down. Do i have to install kube-state-metrics to get each pod metrics rather than using service discovery?

Prometheus kuberentes-pods Get “https:// xx.xx.xx:443 /metrics”: dial tcp xx.xx.xx:443: connect: connection refused

I have configured Prometheus on one of the kubernetes cluster node using this How To Install And Configure Prometheus Monitoring System On Linux after that I added following prometheus.yml file. I can list nodes and apiservers but for pods, all the pods shows down and error Get “https:// xx.xx.xx:443 /metrics”: dial tcp xx.xx.xx:443: connect: connection refused and for some pods the status is unknown. when i can list the nodes and api servers? why it shows connection refused? is it a bug or some…

Are those pods instrumented and are running the metrics listener on port 443?

These are our application pods, Isn’t prometheus temporarily saves metrics in /metrics with random port?
