I have one more cluster and there grafana is working fine. I thing i observe there is: https://<hostname>:8443 --- my ambari address
And when i click on Grafana UI link its: http://<hostname>:3000 so the difference here is grafana is going to http here not on https.
can you tell me how can we resolve this?
