# Add the Prometheus package repository to your list of software sources
wget -q -O - https://packages.cloud.google.com/apt/doc/apt-key.gpg | sudo apt-key add -
echo "deb https://packages.cloud.google.com/apt/prometheus-bionic/ stable main" | sudo tee /etc/apt/sources.list.d/prometheus.list

# Update your package lists
sudo apt update

# Enable and start the Prometheus service

Prometheus listens on port 9090 by default. The web interface can be accessed by entering the server's IP address followed by port 9090 into your web browser's address bar. http://<IP_address>:9090

  1. Extract the downloaded file:
1

tar xvf prometheus.tar.gz


  1. Move into the extracted directory:
1

cd prometheus-*


  1. Copy the necessary configuration files:
1
2

sudo cp prometheus /usr/local/bin/
sudo cp promtool /usr/local/bin/

sudo mkdir /etc/prometheus
sudo mkdir /var/lib/prometheus
sudo chown prometheus:prometheus /etc/prometheus
sudo chown prometheus:prometheus /var/lib/prometheus


  1. Move the configuration files to the appropriate directories:
1

sudo cp -r consoles/ console_libraries/ /etc/prometheus/


  1. Assign ownership of the directories and files to the prometheus user:
1
2

sudo chown -R prometheus:prometheus /etc/prometheus/consoles
sudo chown -R prometheus:prometheus /etc/prometheus/console_libraries


  1. Configure Prometheus:

  - job_name: 'prometheus'
    static_configs:
