### 1. Install Netdata (if not already installed)

```bash
# Basic installation
bash <(curl -Ss https://get.netdata.cloud/kickstart.sh)

# Or with automatic updates enabled
bash <(curl -Ss https://get.netdata.cloud/kickstart.sh) --auto-update
```

### 2. Install Prometheus PVE Exporter (for Proxmox VE monitoring)

```bash
# Install dependencies
apt-get update
apt-get install -y python3-pip python3-dev

# Install the exporter
pip3 install prometheus-pve-exporter

# Create a service file for the exporter
cat > /etc/systemd/system/pve_exporter.service << 'END'
[Unit]
Description=Prometheus PVE Exporter
After=network.target

[Service]
Type=simple
User=root
ExecStart=/usr/local/bin/pve_exporter
Restart=always
RestartSec=10

[Install]
WantedBy=multi-user.target
END

# Create config file
mkdir -p /etc/pve_exporter
cat > /etc/pve_exporter/pve.yml << 'END'
default:
  user: root@pam
  password: your_password
  verify_ssl: false
END

# Set appropriate permissions
chmod 600 /etc/pve_exporter/pve.yml

# Start and enable the service
systemctl daemon-reload
systemctl enable pve_exporter
systemctl start pve_exporter
```

### 3. Configure Netdata Components

#### For Proxmox VE Monitoring:
```bash
cd /etc/netdata
sudo ./edit-config go.d/prometheus.conf
```

Add the configuration shown in the "Proxmox VE Configuration Example" section.

#### For ZFS Pools Monitoring:
```bash
cd /etc/netdata
sudo ./edit-config go.d/zfspool.conf
```

Add the configuration shown in the "ZFS Pool Configuration Example" section.

#### For S.M.A.R.T. Monitoring:
```bash
cd /etc/netdata
# Make sure smartmontools is installed
apt-get install -y smartmontools

# Configure Netdata S.M.A.R.T. monitoring
sudo ./edit-config go.d/smartctl.conf
```

Add the configuration shown in the "S.M.A.R.T. Configuration Example" section.

### 4. Restart Netdata to Apply Changes

```bash
sudo systemctl restart netdata
```

### 5. Verify Monitoring is Working

Visit the Netdata dashboard at:
```
http://your_server_ip:19999
```

You should see sections for:
- Proxmox VE metrics (under "prometheus/proxmox" or similar)
- ZFS pools metrics
- S.M.A.R.T. metrics for your storage devices

### 6. Troubleshooting

If any component is not showing up:

#### Check Netdata Logs:
```bash
journalctl -u netdata -f
```

#### Check Prometheus PVE Exporter:
```bash
# Test if the exporter is providing metrics
curl http://localhost:9221/metrics | head

# Check the exporter logs
journalctl -u pve_exporter -f
```

#### Test S.M.A.R.T. Capabilities:
```bash
# Check if smartctl can access your drives
smartctl -i /dev/sda
```

#### Debug Netdata Collectors:
```bash
# For ZFS pools collector
/usr/libexec/netdata/plugins.d/go.d.plugin -d -m zfspool

# For S.M.A.R.T. collector
/usr/libexec/netdata/plugins.d/go.d.plugin -d -m smartctl

# For Prometheus collector (Proxmox)
/usr/libexec/netdata/plugins.d/go.d.plugin -d -m prometheus
```
