This lets you add a custom feed for Prometheus / Grafana for crypto projects.
If you havent yet set up prometheus/grafana check out this guide here Avax Node Monitoring Guide
sudo apt-get install nodejs
Edit your prometheus yml file with
sudo nano /etc/prometheus/prometheus.yml adding in the content of prometheus yml under you other jobs. After updating and saving use to restart prometheus sudo systemctl restart prometheus. Then do sudo systemctl status prometheus to see if prometheus is working fine. If it isnt then you need to redo the config and make sure your spacing is correct.
If you want to open your ports to view the prometheus dashboard/jobs use
sudo ufw allow 9090/tcp replace your port # for each job
Run avax-app.js script to pull these data feeds on port 9800
run with nohup to keep running after terminal is closed
nohup node avax-app.js & or nohup node generalized-app.js & depending on which script you want to use.
Automatically start the script on reboot by editing your crontab with crontab -e and adding the line @reboot sh -c 'cd /home/app/directory && pm2 start avax-app.js' (or generalized-app.js)
sudo lsof -i :9800 Find PID of program using port 9800
kill -9 pid Kill via PID
