Key Performance Metrics
System Metrics
| Metric | Target | Critical Threshold |
|---|---|---|
| CPU Usage | <70% average | >90% sustained |
| Memory Usage | <80% | >95% |
| Disk I/O | <80% capacity | >95% capacity |
| Network Bandwidth | <70% capacity | >90% capacity |
Node Metrics
| Metric | Target | Impact |
|---|---|---|
| Uptime | 99%+ | Direct reward multiplier |
| Response Time | <100ms | TrustFingerprint score |
| Task Completion Rate | 99%+ | Reward eligibility |
| Peer Connections | 20+ | Network health |
TrustFingerprint Components
The TrustFingerprint score is calculated from:
- Uptime (40% weight): Historical availability
- Performance (30% weight): Task completion speed and accuracy
- Reliability (20% weight): Consistency over time
- 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
- Identify process:
toporhtop - Check for runaway processes
- Verify node configuration
- Consider hardware upgrade
Memory Leaks
- Monitor memory over time
- Restart node if memory grows continuously
- Check for software updates
- Report issue if persistent
Network Latency
- Test connection:
ping 8.8.8.8 - Check bandwidth:
speedtest-cli - Verify router configuration
- Consider ISP upgrade
Low TrustFingerprint Score
- Review historical performance
- Identify periods of downtime
- Check task completion rate
- 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:
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
