Grafana at http://XXX.XXX.XXX.XXX:3000/, replacing XXX.XXX.XXX.XXX with the IP address of your server. If you do not know the IP address, run ifconfig.Default username admin. Default password admin. Grafana will ask you to set a new password.Optional Service AliasOptionally edit the grafana-server.service file to add "grafana" as an alias to "grafana-server". I generally forget that the default name for this service is grafana-server.sudo nano /lib/systemd/system/grafana-server.serviceAt the end of this file, in the [Install] section, add the following line:Setup Prometheus Data SourceOn the left-hand menu, hover over the gear menu and click on Data Sources.Then click on the Add Data Source button.Hover over the Prometheus card on screen, then click on the Select button.Enter http://127.0.0.1:9090/ into the URL field, then click Save & Test.Install Grafana DashboardHover over the plus symbol icon in the left-hand menu, then click on Import.Copy and paste the dashboard at https://raw.githubusercontent.com/metanull-operator/eth2-grafana/master/eth2-grafana-dashboard-single-source-beacon_node.json into the "Import via panel json" text box on the screen.Then click the Load button.Then click the Import button.Note: At this point in the process, any widgets showing details from the validator will show "N/A", because the validator still has no keys configured.
