Data Agent Installation Guide

This guide provides detailed instructions for installing a data agent on an Ubuntu 24.04 LTS (Noble Numbat) EC2 instance, incorporating the latest Ubuntu features and best practices.

Prerequisites

• EC2 instance running Ubuntu 24.04 LTS

• SSH access to your instance

• Appropriate IAM roles configured

• Sudo access on the instance

Step 1: Initial Server Setup

Connect to your Ubuntu 24.04 EC2 instance:

ssh -i your-key.pem ubuntu@your-instance-ip

Update the package manager to use the new Ubuntu 24.04 repositories:

sudo apt update && sudo apt full-upgrade -y

Enable automatic security updates (recommended for production):

sudo apt install -y unattended-upgrades
sudo dpkg-reconfigure -plow unattended-upgrades

Step 2: Install Dependencies

Install required packages (note: Ubuntu 24.04 comes with Python 3.12 by default):

sudo apt install -y \
    curl \
    wget \
    systemd \
    python3-pip \
    python3-venv \
    software-properties-common

Step 3: Install the Data Agent

Create required directories:

sudo mkdir -p /opt/dataagent
cd /opt/dataagent

Download and install the agent (using the new deb format for Ubuntu 24.04):

# Import the repository GPG key
curl -fsSL https://downloads.dataagent.com/gpg/key.gpg | sudo gpg --dearmor -o /usr/share/keyrings/dataagent-archive-keyring.gpg

# Add the repository
echo "deb [signed-by=/usr/share/keyrings/dataagent-archive-keyring.gpg] https://downloads.dataagent.com/apt noble main" | \
    sudo tee /etc/apt/sources.list.d/dataagent.list

# Update package list and install
sudo apt update
sudo apt install -y dataagent

Step 4: Configure the Agent

Create and secure the configuration directory:

sudo mkdir -p /etc/dataagent
sudo chmod 750 /etc/dataagent

Create the configuration file using the new YAML format:

sudo nano /etc/dataagent/config.yaml

Add the following configuration (updated for Ubuntu 24.04):

agent:
  id: "ec2-agent-{{INSTANCE_ID}}"
  api_key: "YOUR_API_KEY"

collection:
  interval: 60
  metrics_format: "opentelemetry"  # New in 24.04

endpoints:
  api: "https://api.dataagent.com"
  metrics: "https://metrics.dataagent.com"
  traces: "https://traces.dataagent.com"  # New in 24.04

logging:
  level: info
  path: /var/log/dataagent
  max_size: 100M
  max_files: 5
  format: "json"  # New in 24.04

security:
  tls:
    min_version: "TLS1.3"  # Required in 24.04
    verify_cert: true

Step 5: Configure Systemd Service

The service file is now managed by systemd generator in Ubuntu 24.04. Create an override:

sudo mkdir -p /etc/systemd/system/dataagent.service.d
sudo nano /etc/systemd/system/dataagent.service.d/override.conf

Add the following content:

[Service]
# Security enhancements for Ubuntu 24.04
SystemCallFilter=@system-service
SystemCallErrorNumber=EPERM
NoNewPrivileges=yes
ProtectSystem=strict
ProtectHome=yes
PrivateTmp=yes
PrivateDevices=yes
ProtectKernelTunables=yes
ProtectKernelModules=yes
ProtectControlGroups=yes
RestrictNamespaces=yes
LockPersonality=yes
RestrictRealtime=yes
RestrictSUIDSGID=yes
CapabilityBoundingSet=CAP_NET_BIND_SERVICE

# Resource limits
LimitNOFILE=65536
LimitNPROC=4096

# Environment
Environment=LANG=C.UTF-8

Step 7: Start and Enable Services

Reload and start services:

sudo systemctl daemon-reload
sudo systemctl start dataagent
sudo systemctl enable dataagent

Troubleshooting

Ubuntu 24.04-specific troubleshooting:

1. Check systemd service status:

sudo systemctl status dataagent

2. View structured logs:

journalctl -u dataagent -o json-pretty
