Hello all One of my servers has an internal and an external ip address. The hostname belongs to the external address, while the prometheus server should connect to the internal address. myserver.domain.com -> 10.0.0.1 external example myserver.domain -> 192.168.0.1 internal example Hostname defined in Uyuni = myserver.domain.com IP Address defined in Uyuni = 192.168.0.1 The server has only one ip - the external ip ends on the firewall (NAT) and is forwarded to the internal ip. When I activate the prometheus node exporter formula on this server, the prometheus server tries to connect the external ip with this error: Get "http://myserver.domain.com:9100/metrics": dial tcp 10.0.0.1:9100: connect: connection refused What can I do to change the connection string to: http://myserver.domain:9100/metrics or http://192.168.0.1:9100/metrics that is accessible from the prometheus server? I tried to change the prometheus_exporter Address: field from :9100 to myserver.domain:9100 and the Argument field from --web.listen-address=":9100" to --web.listen-address="myserver.domain:9100", but that changes nothing. The prometheus server catches the mgr-clients from the uyuni server: # -------------------- # Auto discover clients of uyuni # -------------------- - job_name: 'mgr-clients' uyuni_sd_configs: - host: https://uyuni.domain username: admin password: <password> Same problem with the apache Exporter :) Some ideas?
