Grafana + Graphite

This is a way to setup a Grafana + Graphite in your local machine or VPS like the one from Hetzner.

Installation

On your local machine

• Copy docker-compose.yml to your desired folder
• Open docker-compose.yml and modify GF_SECURITY_ADMIN_USER and GF_SECURITY_ADMIN_PASSWORD to your desired values. These are your grafana login credentials.
• Run docker compose -p my-grafana-project up -d
• IMPORTANT: run docker compose -p my-grafana-project down to turn it off immediately
• Open ./graphite_data/graphite_conf/storage-aggregation.conf with your favorite text editor and change all xFilesFactor values to 0
• Save file and quit the text editor
• Run docker compose -p my-grafana-project up -d

Open the browser and visit http://localhost:3001. Login with the username and password from docker-compose.yml file.

When grafana website is loaded, go to Menu -> Connections -> Add new connection -> Search for "graphite" -> Click on it -> Click on "Add new data source" -> HTTP -> URL -> Enter host.docker.internal:2002 -> Scroll to the bottom -> Click "Save & test"

Don't forget to put new grafana and graphite folders to .gitignore:

grafana_data
graphite_data

And that's it!

On Hetzner

Sending stats

On your local machine

Ruby:

def measure(path, value, statsd_type)
  sock = UDPSocket.new
  message = "#{path}:#{value}|#{statsd_type}"

  sock.send(message, 0, "localhost", 8125)
  sock.close
end

measure("worker.my_worker.execution_time", 123, 'ms')

On Hetzner

Same as on your local machine, just use your Hetzner server's IP address instead of localhost.
