Getting Started with NebulaImage Monitoring

NebulaImage Monitoring provides a pre-wired observability stack on Ubuntu 24.04 LTS: Prometheus collects metrics, Node Exporter exposes system metrics, and Grafana provides dashboards — all configured and started automatically at launch.

Prerequisites

  • An active AWS account
  • An EC2 key pair in your target region
  • A security group allowing port 22 (SSH) from your IP

Launch

  1. Find NebulaImage Monitoring on AWS Marketplace and subscribe
  2. Launch an EC2 instance (t3.small or larger)
  3. SSH in:
ssh -i your-key.pem ubuntu@<ec2-ip>

Verify services are running

sudo systemctl status prometheus
sudo systemctl status grafana-server
sudo systemctl status node_exporter

All three should show active (running).

Access the interfaces

Open your EC2 security group to allow the following ports from your IP only:

| Service | Port | URL | |---------------|------|----------------------------------| | Grafana | 3000 | http://<ec2-ip>:3000 | | Prometheus | 9090 | http://<ec2-ip>:9090 | | Node Exporter | 9100 | http://<ec2-ip>:9100/metrics |

First login to Grafana

  1. Navigate to http://<ec2-ip>:3000
  2. Log in with username admin
  3. You will be prompted to set a new admin password on first login

The Node Exporter dashboard is pre-imported. You should immediately see CPU, memory, disk, and network metrics.

Next steps

  • Configuration — Add more scrape targets and dashboards
  • Security — Secure Grafana and Prometheus before production use
