    Monitoring & Metrics

    Track performance and health of your cloud instances

    The Cloud Control Panel provides basic performance metrics for your instances. For advanced monitoring, you can deploy third-party monitoring solutions on your instances.

    Built-in Metrics

    The Cloud Control Panel displays basic metrics for each instance:

    CPU Usage

    Percentage of CPU utilization over time

    Network Traffic

    Inbound and outbound bandwidth usage

    Disk I/O

    Read/write operations

    Viewing Metrics

    1
    Log into the Cloud Control Panel
    2
    Select your instance from the Instances tab
    3
    Click the Metrics or Overview tab
    4
    View graphs showing historical performance data

    Installing Monitoring Agents

    For more detailed monitoring, install monitoring agents on your instances:

    1. Netdata (Free, Open Source)

    Real-time performance monitoring with beautiful dashboards:

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

# Access at http://your-ip:19999

    2. Grafana + Prometheus

    Industry-standard monitoring stack:

    # Install Prometheus
wget https://github.com/prometheus/prometheus/releases/download/v2.45.0/prometheus-2.45.0.linux-amd64.tar.gz
tar xvfz prometheus-*.tar.gz

# Install Grafana
apt-get install -y adduser libfontconfig1
wget https://dl.grafana.com/oss/release/grafana_10.0.0_amd64.deb
dpkg -i grafana_10.0.0_amd64.deb
systemctl start grafana-server

    3. Uptime Kuma

    Monitor service availability:

    # Install with Docker
docker run -d --restart=always \
  -p 3001:3001 \
  -v uptime-kuma:/app/data \
  --name uptime-kuma \
  louislam/uptime-kuma:1

    See our Uptime Kuma deployment guide for detailed instructions.

    Key Metrics to Monitor

    CPU Usage

    # Monitor CPU usage over time
top
htop

# Check average CPU load
uptime
cat /proc/loadavg

    Memory Usage

    # Check memory usage
free -h

# View top memory consumers
ps aux --sort=-%mem | head

    Disk Space

    # Check disk usage
df -h

# Find large directories
du -sh /* | sort -h

    Network Traffic

    # Install iftop for real-time network monitoring
apt install iftop
iftop -i eth0

    Setting Up Alerts

    Simple Email Alerts with Cron

    # Create monitoring script
cat > /usr/local/bin/disk-check.sh << 'EOF'
#!/bin/bash
USAGE=$(df / | tail -1 | awk '{print $5}' | sed 's/%//')
if [ $USAGE -gt 80 ]; then
  echo "Disk usage is above 80%: $USAGE%" | mail -s "Disk Alert" admin@example.com
fi
EOF

chmod +x /usr/local/bin/disk-check.sh

# Add to crontab (run hourly)
echo "0 * * * * /usr/local/bin/disk-check.sh" | crontab -

    Log Management

    System Logs

    # View system logs
journalctl -xe

# Follow logs in real-time
journalctl -f

# View specific service logs
journalctl -u nginx

    Application Logs

    Common log locations:

    • /var/log/nginx/ - Nginx web server logs
    • /var/log/apache2/ - Apache web server logs
    • /var/log/mysql/ - MySQL database logs

    Performance Testing

    Network Speed Test

    # Install speedtest-cli
apt install speedtest-cli

# Run speed test
speedtest-cli

    Disk Performance Test

    # Write test
dd if=/dev/zero of=/tmp/test bs=1G count=1 oflag=direct

# Read test
dd if=/tmp/test of=/dev/null bs=1G count=1 iflag=direct

# Clean up
rm /tmp/test

    Pro Tip

    Start with simple monitoring using built-in tools and free solutions like Netdata. Add more sophisticated monitoring as your needs grow and you understand your application's behavior better.
