I got to grafana servers first one is monitoring kubernetes installed on the master the second is on a separate Vm both are pinging !
I need to merge both of them in order to access them with the same URL
I tried to added kubernetes prometheus ( my first Grafana server) as a data source on the second one but i got an ‘’ error gateway’’ !
some help please !

Hi,
I suggest looking at the Grafana logs. Also try accessing your data
source URL of the problematic Prometheus instance from your Grafana
server via curl. Maybe there is some firewall restriction in place (ping
is not sufficient, you will need tcp access on the relevant port [9090,
by default]).

Kind regards,
Christian
