Hi,
Yes, I have prometheus running.

In the block-producing node I just run with:

 -e PROMETHEUS_HOST="0.0.0.0"
 -e PROMETHEUS_PORT="12798"
 -p 1798:1798

You can for example look in your config.json file for your node, to make sure that the Prometheus part looks as following:

 "hasPrometheus": [
  "0.0.0.0",
  12798
 ],

If you have already initialized your node without having the correct prometheus parameter, the config.json has been created without them. The container will not replace an already initialized configuration.

Then I've set up firewall rules so its only the LAN IP of the relay nodes, and the prometheus node which can connect to port 12798 and port 3000 on the block-producing node. All other traffic is blocked.

On another host (lets call it the prometheus host), i run the following containers:

docker run -d \
    --restart=unless-stopped \
    --network=cardano \
    --name prometheus \
    -v $PWD/config/prometheus/:/config/ \
    prom/prometheus:latest


docker run -d \
    --restart=unless-stopped \
    --network=cardano  \
    --name grafana \
    -p 9000:3000 \
    grafana/grafana

My Prometheus config.yml located in $PWD/config/prometheus/config.yml, on the prometheus host, looks as following:

global:
  scrape_interval:     15s

  external_labels:
    monitor: 'codelab-monitor'

scrape_configs:
  - job_name: 'cardano'  # To scrape data from the cardano node
    scrape_interval: 5s
    static_configs:
      - targets: ['<LAN IP of relay>:12798']
        labels:
          alias: 'relay1'
          type:  'cardano-node'  
      - targets: ['<LAN ip of block-producing>:12798']
        labels:
          alias: 'block-producing1'
          type:  'cardano-node'

  - job_name: 'node' # To scrape data from a node exporter to monitor your linux host metrics.
    scrape_interval: 5s
    static_configs:
    - targets: ['<LAN IP of relay>:9100']
      labels:
        alias: 'relay1'
        type:  'node'  
    - targets: ['<LAN ip of block-producing>:9100']
      labels:
        alias: 'block-producing1'
        type:  'node'

Then I configure Grafana to fetch data from the prometheus container running besides the Grafana container, and add the dashboard settings that IOHK has published, with a few modifications. I can share my grafana dashboard if you want, when you get it running.
