Setting Up Dashboards
- Prometheus is a monitoring platform that collects metrics from monitored targets by scraping metrics HTTP endpoints on these targets. Official documentation is available here.
- Grafana is a dashboard used to visualize the collected data.
Install prometheus and prometheus node exporter.
relaynode1
block producer node
sudo apt-get install -y prometheus prometheus-node-exporter
sudo apt-get install -y prometheus-node-exporter
Install grafana.
relaynode1
sudo apt-get install -y apt-transport-https
sudo apt-get install -y software-properties-common wget
sudo wget -q -O /usr/share/keyrings/grafana.key https://apt.grafana.com/gpg.key
relaynode1
echo "deb [signed-by=/usr/share/keyrings/grafana.key] https://apt.grafana.com stable main" | sudo tee -a /etc/apt/sources.list.d/grafana.list
relaynode1
sudo apt-get update && sudo apt-get install -y grafana
Enable services so they start automatically.
relaynode1
block producer node
sudo systemctl enable grafana-server.service
sudo systemctl enable prometheus.service
sudo systemctl enable prometheus-node-exporter.service
sudo systemctl enable prometheus-node-exporter.service
Update prometheus.yml located in
/etc/prometheus/prometheus.ymlChange the <block producer ip address> in the following command.
relaynode1
cat > prometheus.yml << EOF
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: ['localhost:9100']
labels:
alias: 'relaynode1'
type: 'cardano-node'
- targets: ['<block producer ip address>:9100']
labels:
alias: 'block-producer-node'
type: 'cardano-node'
- targets: ['<block producer ip address>:12798']
labels:
alias: 'block-producer-node'
type: 'cardano-node'
- targets: ['localhost:12798']
labels:
alias: 'relaynode1'
type: 'cardano-node'
EOF
sudo mv prometheus.yml /etc/prometheus/prometheus.yml
Finally, restart the services.
relaynode1
sudo systemctl restart grafana-server.service
sudo systemctl restart prometheus.service
sudo systemctl restart prometheus-node-exporter.service
Verify that the services are running properly:
relaynode1
sudo systemctl status grafana-server.service prometheus.service prometheus-node-exporter.service
Update
config.json config files with new hasEKG and hasPrometheus ports.block producer node
relaynodeN
cd $NODE_HOME
sed -i config.json -e "s/127.0.0.1/0.0.0.0/g"
cd $NODE_HOME
sed -i config.json -e "s/127.0.0.1/0.0.0.0/g"
A note on port forwarding and firewall configuration.
Block producer node ports 12798 and 9100 should be reachable from the relaynode1, which is hosting Prometheus and Grafana.
- Port 12798 is for Cardano-Node's prometheus metrics.
- Port 9100 is for node-exporter metrics.
Stop and restart your stake pool.
block producer node
relaynode1
sudo systemctl restart cardano-node
sudo systemctl restart cardano-node
Verify the metrics are working by querying the prometheus port.
block producer and relaynodes
curl -s 127.0.0.1:12798/metrics
# Example output:
# rts_gc_par_tot_bytes_copied 123
# rts_gc_num_gcs 345
# rts_gc_max_bytes_slop 4711111
# cardano_node_metrics_served_block_count_int 8112
# cardano_node_metrics_Stat_threads_int 8
# cardano_node_metrics_density_real 4.67
Do not expose Grafana (port 3000) to the public internet as this invites a new attack surface! A secure solution would be to access Grafana through a ssh tunnel.
Example of how to create a ssh tunnel in Linux or MacOS:
ssh -N -v <user>@<staking.node.ip.address> -L 3000:localhost:3000
Navigate to Connection > SSH > Tunnels > Enter Source Port
3000 > Enter Destination localhost:3000 > Click Add
Now you can access Grafana on your local machine by pointing a web browser to http://localhost:3000
- 1.Open http://localhost:3000 (if using ssh tunnel or on relaynode1) or http://<your relaynode1 ip address>:3000 in your local browser.
- 2.Login with admin / admin
- 3.Change password
- 4.Click the configuration gear icon, then Add data Source
- 5.Select Prometheus
- 6.Set Name to "Prometheus"
- 7.Set URL to http://localhost:9090
- 8.Click Save & Test
- 9.
- 10.Click Create + icon > Import
- 11.Add dashboard by Upload JSON file
- 12.Click the Import button.
