@gustavosr98 Bravo! Thanks for the feedback!

The metrics in these dashboards are metrics exposed via the node exporter which lives inside grafana-agent . To see them select Grafana Agent from the applications (image one)

To view CPU usage then scroll back to the dashbord (image two)

Right now I am talking to ob11y to see if we can configure grafana agent and MongoDB so that the dashboard can be populated automatically
