Random Useless Values shown in Dashboard about chia-monitor HOT 3 OPEN

I had the same problem, even though I selected the correct source, dashboard was showing random values. Mine solved setting my "Prometheus-1" (the instance monitoring chia-monitor) as the default datasource:

from chia-monitor.

Hey @InvaderDolan, the data source in Grafana needs to point to the Prometheus instance and not to the /metrics page of the monitor. By default, the Prometheus server will use port 9090, so yours is probably running on localhost:9090.

Does changing the Prometheus data source URL in your Grafana to localhost:9090 fix your dashboard?

Thank you for you answer. But I reinstalled grafana, tried everything from zero and then did your steps. I still have configured prometheus.yaml as before and tried http://localhost:9090 but now I get an error "Bad Gateway" and there is nothing now at all on this address. But 8000 and 8000/metrics still show some values.
What did I do wrong? Thank you for your attention.
