To read PC data as disk usage you needs node-exporter

Hm, that’s strange, I thought I did install node-exporter. I think I should try again.

If you installed, then you need to configure prometheus to read those metrics…

usually it runs on 9100 port so something like this should be in your prometheus.yml

 - job_name: "node"

    static_configs:
      - targets: ["producer.hostname.com:9100"]
        labels:
          alias: 'producer'
          type:  'cardano-node'

These is my full config file:

github.com

os11k/grafana-with-prometheus/blob/main/etc-prometheus/prometheus.yml

global:
  scrape_interval:     15s # By default, scrape targets every 15 seconds.

  # Attach these labels to any time series or alerts when communicating with
  # external systems (federation, remote storage, Alertmanager).
  external_labels:
    monitor: 'codelab-monitor'

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label job=<job_name> to any timeseries scraped from this config.
  - job_name: 'prometheus'

    static_configs:
      - targets: ['producer.hostname.com:12798']
        labels:
          alias: 'producer'
          type:  'cardano-node'
      - targets: ['relay1.hostname.com:12798']
