## Installation (Per Server)

### One-Line Install

**On each server:**

```bash
# Install Netdata
bash <(curl -Ss https://my-netdata.io/kickstart.sh)

# The installer will:
# - Auto-detect your OS
# - Install dependencies
# - Compile and install Netdata
# - Start the service
# - Open port 19999
```

**Installation takes:** 2-5 minutes per server

---

## Step-by-Step Deployment

### Phase 1: Install on Command Center (10 min)

```bash
# SSH to Command Center
ssh root@63.143.34.217

# Run installer
bash <(curl -Ss https://my-netdata.io/kickstart.sh)

# Wait for installation to complete
# Answer prompts (usually just press Enter for defaults)

# Verify installation
systemctl status netdata

# Should show: active (running)

# Test dashboard
curl http://localhost:19999

# Should return HTML
```

**Open in browser:** `http://63.143.34.217:19999`

You should see the Netdata dashboard!

---

bash <(curl -Ss https://my-netdata.io/kickstart.sh)

# Verify
systemctl status netdata

# Test
curl http://localhost:19999
```

**Open in browser:** `http://38.68.14.26:19999`

---

### Phase 3: Install on NC1 (5 min)

```bash
# SSH to NC1
ssh root@216.239.104.130

# Run installer
bash <(curl -Ss https://my-netdata.io/kickstart.sh)

# Verify
systemctl status netdata

# Test

# Test
curl http://localhost:19999
```

**Open in browser:** `http://64.50.188.14:19999`

---

## Post-Installation Configuration

### 1. Configure UFW Firewall

**On each server:**

```bash
# Allow Netdata port from Michael's management IP only
ufw allow from MICHAEL_MANAGEMENT_IP to any port 19999 proto tcp

# Verify
ufw status | grep 19999
```

**Security note:** Netdata dashboards contain sensitive server information. Only allow access from trusted IPs.

---

### 2. Set Up Parent-Child Streaming (Optional)

**Benefit:** View all servers from one dashboard (Command Center)

**On Command Center (parent):**

```bash
# Edit config
nano /etc/netdata/stream.conf

# Add:
[11111111-2222-3333-4444-555555555555]
    enabled = yes
    default history = 3600
    default memory mode = save
    health enabled = yes
```

**On TX1, NC1, Ghost (children):**

```bash
# Edit config
nano /etc/netdata/stream.conf

# Add:
[stream]
    enabled = yes
    destination = 63.143.34.217:19999
    api key = 11111111-2222-3333-4444-555555555555
    
# Restart netdata
systemctl restart netdata
```

**Result:** All server metrics visible on Command Center dashboard

---

### 3. Configure Alerts

**Edit alert config:**

```bash
nano /etc/netdata/health.d/custom.conf
```

**Example alerts:**

```yaml
# Alert when CPU usage > 80% for 5 minutes
alarm: cpu_usage
    on: system.cpu
  calc: $user + $system
 every: 1m
  warn: $this > 80
  crit: $this > 95
 delay: up 5m down 15m
  info: CPU usage is too high

# Alert when RAM usage > 90%
alarm: ram_usage
    on: system.ram
  calc: $used * 100 / ($used + $free)
 every: 1m
  warn: $this > 90
  crit: $this > 95
 delay: up 5m down 15m
  info: RAM usage is too high

# Alert when disk space < 20%
alarm: disk_space
    on: disk.space
  calc: $avail * 100 / ($avail + $used)
 every: 1m
  warn: $this < 20
  crit: $this < 10
 delay: up 5m down 15m
  info: Disk space is running low
```

**Reload config:**

```bash
killall -USR2 netdata
```

---

### 4. Discord Integration (Optional)

**Set up Discord webhook for alerts:**

```bash
# Edit alarm notification config
nano /etc/netdata/health_alarm_notify.conf

# Find Discord section and configure:
SEND_DISCORD="YES"
DISCORD_WEBHOOK_URL="YOUR_DISCORD_WEBHOOK_URL_HERE"
DEFAULT_RECIPIENT_DISCORD="network-alerts"
```

**Test alert:**

```bash
# Trigger test alert
/usr/libexec/netdata/plugins.d/alarm-notify.sh test
```

Check Discord for test notification.

## Dashboard Access

### Quick Access Links

**Save these bookmarks:**

- Command Center: http://63.143.34.217:19999
- TX1: http://38.68.14.26:19999
- NC1: http://216.239.104.130:19999

---

### Key Metrics to Monitor

**CPU:**
- User % (application load)
- System % (kernel load)
- IOWait % (disk bottleneck indicator)

**RAM:**
- Used vs Available
- Cache (should be high, that's good!)
- Swap usage (should be low)

**Disk:**
- Disk space remaining
- Read/write speeds
- IOPs

**Network:**
- Bandwidth usage
- Packet drops
- Connection count

**Minecraft Servers (TX1/NC1):**
- Java heap usage
- GC activity
- Thread count

---

## Maintenance

### Daily

- Quick glance at dashboards (bookmark all 4)
- Check for any red alerts

### Weekly

- Review CPU/RAM trends
- Check disk space projections
- Verify alerts working

### Monthly

- Review historical data
- Adjust alert thresholds if needed
- Update Netdata if new version available

---

## Updates

**Check for updates:**

```bash
# On each server
netdata-updater.sh
```

**Or auto-update (recommended):**

Updates automatically check daily and install automatically.

---

## Troubleshooting

### Dashboard won't load

**Check service:**
```bash
systemctl status netdata
```

**Restart if needed:**
```bash
systemctl restart netdata
```

**Check firewall:**
```bash
ufw status | grep 19999
telnet localhost 19999
```

---

### High CPU usage from Netdata

Netdata should use < 3% CPU normally.

**Check what's using resources:**
```bash
# Disable some plugins if needed
nano /etc/netdata/netdata.conf

# Under [plugins], disable unused:
python.d = no
node.d = no
```

---

### Streaming not working

**Verify:**
- Parent (Command Center) has stream.conf with API key
- Children have correct parent IP
- Port 19999 accessible from children to parent
- API keys match exactly

**Debug:**
```bash
# On child
tail -f /var/log/netdata/error.log | grep stream
```

---

### Alerts not sending to Discord

**Check:**
- Discord webhook URL correct
- `SEND_DISCORD="YES"` set
- Test alert sent successfully

**Debug:**
```bash
/usr/libexec/netdata/plugins.d/alarm-notify.sh test debug
```

---
