Performance Monitoring

Overview

Effective performance monitoring is essential for maintaining high TrustFingerprint™ scores and maximizing node rewards. This guide covers monitoring tools, key metrics, and optimization strategies.

Monitoring Stack

Recommended Tools

• Prometheus: Metrics collection and storage
• Grafana: Visualization and dashboards
• Alertmanager: Alert routing and management
• Node Exporter: System metrics collection

Installation

See Setup Guide for installation instructions.

Key Performance Metrics

System Metrics

Node Metrics

TrustFingerprint™ Components

The TrustFingerprint™ score is calculated from:

1. Uptime (40% weight): Historical availability
2. Performance (30% weight): Task completion speed and accuracy
3. Reliability (20% weight): Consistency over time
4. Participation (10% weight): Governance and network engagement

Monitoring Dashboards

System Dashboard

Monitor system health:

- CPU usage by core
- Memory usage and swap
- Disk I/O and space
- Network traffic
- System load average

Node Dashboard

Track node-specific metrics:

- Node uptime
- Task completion rate
- Reward earnings
- TrustFingerprint™ score
- Peer connections
- Block/transaction processing

Alert Dashboard

Configure alerts for:

- High CPU/memory usage
- Low disk space
- Network connectivity issues
- Node offline
- Low TrustFingerprint™ score
- Missed tasks

Alert Configuration

Critical Alerts

Immediate action required:

• Node offline >5 minutes
• CPU >95% for >10 minutes
• Memory >98%
• Disk space <5%
• Network disconnected

Warning Alerts

Investigation needed:

• CPU >80% for >1 hour
• Memory >85%
• Disk space <20%
• TrustFingerprint™ score declining
• Task completion rate <95%

Info Alerts

Awareness only:

• Software updates available
• Reward distribution completed
• Governance proposals active
• Network announcements

Performance Optimization

CPU Optimization

# Check CPU frequency scaling
cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
# Set to performance modeecho performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor

Memory Optimization

# Adjust swappiness
sudo sysctl vm.swappiness=10
# Clear cache if needed
sudo sync && sudo sysctl -w vm.drop_caches=3

Network Optimization

# Increase network buffer sizes
sudo sysctl -w net.core.rmem_max=134217728
sudo sysctl -w net.core.wmem_max=134217728

Disk Optimization

# Enable TRIM for SSDs
sudo fstrim -v /
# Check disk health
sudo smartctl -a /dev/sda

Troubleshooting Performance Issues

High CPU Usage

1. Identify process: top or htop
2. Check for runaway processes
3. Verify node configuration
4. Consider hardware upgrade

Memory Leaks

1. Monitor memory over time
2. Restart node if memory grows continuously
3. Check for software updates
4. Report issue if persistent

Network Latency

1. Test connection: ping 8.8.8.8
2. Check bandwidth: speedtest-cli
3. Verify router configuration
4. Consider ISP upgrade

Low TrustFingerprint™ Score

1. Review historical performance
2. Identify periods of downtime
3. Check task completion rate
4. Improve system reliability

Best Practices

Daily Tasks

• Check dashboard for alerts
• Verify node is online
• Review overnight performance
• Check reward earnings

Weekly Tasks

• Review performance trends
• Update software if needed
• Check disk space
• Backup configuration

Monthly Tasks

• Analyze TrustFingerprint™ trends
• Optimize system performance
• Review and update alerts
• Plan hardware upgrades if needed

Performance Benchmarking

Baseline Metrics

Record baseline performance after setup:

# CPU benchmark
sysbench cpu run
# Memory benchmark
sysbench memory run
# Disk benchmark
fio --name=random-write --ioengine=libaio --rw=randwrite --bs=4k --size=1G
# Network benchmark
iperf3 -c speedtest.net

Regular Testing

Run benchmarks monthly to detect degradation.

Reporting Issues

If you experience persistent performance issues:

1. Collect diagnostic data:

   # System info
   uname -a
   lscpu
   free -h
   df -h
   # Node logs
   docker-compose logs --tail=1000 > node-logs.txt
   # Metrics export
   curl http://localhost:8080/metrics > metrics.txt
   

2. Report to Discord or GitHub
