Prometheus :

Installation des paquets nécessaires : 

apt-get install prometheus curl

Remplir le fichier /etc/prometheus/prometheus.yml comme ci-dessous : 

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:
  - job_name:       'node'

    scrape_interval: 5s

    static_configs:
      - targets: ['172.31.65.70:9090', '172.31.65.70:3000', '172.31.64.10:53', '172.31.64.30:53', '172.31.64.30:25', '172.31.65.10:80', '172.31.65.20:80', '172.31.65.50:21', '172.31.64.60:3306', '172.31.64.40:80']
