DB_USER=ubec_admin
DB_PASSWORD=<secure-password>
DB_POOL_MIN=5
DB_POOL_MAX=20

# Stellar Network Configuration
STELLAR_NETWORK=public
STELLAR_HORIZON_URL=https://horizon.stellar.org

# Rate Limiting
STELLAR_RATE_LIMIT=3000  # requests per hour

Service Management

Understanding the Service Registry

The Service Registry is the heart of the system architecture. It manages all services, handles initialization order, and provides health monitoring.

Key Principles: - Services are initialized only when first requested (lazy loading) - Dependencies are automatically resolved via topological sorting - All services implement standardized health checks - Services are properly shut down in reverse dependency order

Service Lifecycle

# Service lifecycle managed by context manager
async with registry:
    # Services auto-initialize on first access
    db = await registry.get('database')
    stellar = await registry.get('stellar_client')

    # Perform operations
    await db.execute("SELECT 1")

    # Services auto-cleanup on exit

Registered Services

Service Name Purpose Dependencies Critical
database PostgreSQL connection pool None ✅ Yes
config Configuration management database ✅ Yes
stellar_client Blockchain API client config ✅ Yes
air Air element protocol database, config Yes
water Water element protocol database, config Yes
earth Earth element protocol database, config Yes
fire Fire element protocol database, config Yes
synchronizer Blockchain sync database, stellar_client ✅ Yes
analytics Token analytics database No
distribution Balance management database No
distribution_evaluator Compliance checking database No
holonic_evaluator Ubuntu assessment database No
visualizer Reporting database No
audit Audit logging database Yes
monitoring System health database Yes

Starting the System

The system does NOT run as a daemon by default. All operations are executed via main.py commands:

# System health check
python main.py health --detailed

# Synchronize blockchain data
python main.py sync --full

# Run holonic evaluation
python main.py evaluate --accounts all

# Generate reports
python main.py report --type holonic --format html --output /var/reports/

Creating a Systemd Service (Optional)

For continuous monitoring or scheduled operations, create a systemd service:

# Create service file
sudo nano /etc/systemd/system/ubec-monitor.service

Service File Contents:

[Unit]
Description=UBEC Protocol Monitoring Service
After=network.target postgresql.service

[Service]
Type=simple
User=ubec
Group=ubec
WorkingDirectory=/opt/ubec-protocol
Environment="PATH=/opt/ubec-protocol/venv/bin"
ExecStart=/opt/ubec-protocol/venv/bin/python main.py monitor --continuous
Restart=on-failure
RestartSec=10s
StandardOutput=journal
StandardError=journal

[Install]
WantedBy=multi-user.target
# Enable and start service
sudo systemctl daemon-reload
sudo systemctl enable ubec-monitor.service
sudo systemctl start ubec-monitor.service

# Check status
sudo systemctl status ubec-monitor.service

Monitoring and Health Checks

Health Check Architecture

Every service implements a standardized health check pattern using the ServiceHealthCheck utility (Design Principle #12 - Method Singularity).

Health Status Levels: - HEALTHY - Service operational, all checks passed - DEGRADED - Service functional but experiencing issues - UNHEALTHY - Service not operational - INITIALIZING - Service starting up - UNKNOWN - Health check unavailable

Running Health Checks

# Quick health check
python main.py health

# Detailed health check with service metrics
python main.py health --detailed

# JSON output for monitoring systems
python main.py health --format json > /var/monitoring/ubec-health.json

# Check specific service
python main.py health --service database

Backup Locations: - Primary: /var/backups/ubec/ - Secondary: Network storage (NFS/SMB) - Archive: Offsite/cloud storage

Database Backup

Automated Backup Script:

#!/bin/bash
# /opt/ubec-protocol/scripts/backup-database.sh

BACKUP_DIR=/var/backups/ubec
TIMESTAMP=$(date +%Y%m%d-%H%M%S)
DB_NAME=ubec
DB_USER=ubec_admin

# Create backup directory
mkdir -p $BACKUP_DIR

# Perform backup
pg_dump -U $DB_USER -F c -b -v -f $BACKUP_DIR/ubec-${TIMESTAMP}.dump $DB_NAME

# Compress backup
gzip $BACKUP_DIR/ubec-${TIMESTAMP}.dump

# Remove backups older than 30 days
find $BACKUP_DIR -name "ubec-*.dump.gz" -mtime +30 -delete

# Log completion
echo "$(date): Backup completed: ubec-${TIMESTAMP}.dump.gz" >> /var/log/ubec/backup.log

Schedule via Cron:

Troubleshooting

Common Issues and Solutions

Issue 1: Database Connection Failures

Symptoms:

ERROR - database - Failed to connect: connection refused

Diagnosis:

# Check PostgreSQL status
sudo systemctl status postgresql

# Test connection manually
psql -U ubec_admin -d ubec -h localhost -c "SELECT 1;"

# Check connection pool
python main.py database --pool-status

Resolution:

# Restart PostgreSQL
sudo systemctl restart postgresql

# Check firewall
sudo ufw status

# Verify credentials in .env
cat /opt/ubec-protocol/.env | grep DB_

Issue 2: Stellar Horizon API Rate Limiting

Symptoms:

WARNING - stellar_client - Rate limit exceeded: 3000/3000

Diagnosis:

# Check current rate limit status
python main.py stellar --rate-limit-status

# Review recent API usage
grep "rate_limit" /var/log/ubec/application.log | tail -20

Resolution:

# Wait for rate limit window to reset (logs show reset time)
# Increase rate limit window in .env:
STELLAR_RATE_LIMIT_WINDOW=7200  # 2 hours instead of 1

# Implement exponential backoff (already built-in)
# Reduce synchronization frequency

Issue 3: Synchronization Lag

Symptoms:

WARNING - synchronizer - Sync lag: 45 minutes behind blockchain

Diagnosis:

# Check sync status
python main.py sync --status

# Review synchronizer logs
grep "synchronizer" /var/log/ubec/application.log | tail -50

# Check Stellar Horizon status
curl https://horizon.stellar.org/

Resolution:

# Run incremental sync
python main.py sync --incremental --force

# If persistent, run full sync (during off-peak hours)
python main.py sync --full

# Check system resources
htop
df -h

Issue 4: Service Health Degraded

Symptoms:

⚠️  synchronizer - DEGRADED - Last sync: 25 minutes ago

Diagnosis:

# Check service-specific health
python main.py health --service synchronizer --detailed

# Review service logs
tail -f /var/log/ubec/application.log | grep synchronizer

# Check dependencies
python main.py health --service database
python main.py health --service stellar_client

Resolution:

# Restart application (if using systemd service)
sudo systemctl restart ubec-monitor.service

# Manual sync operation
python main.py sync --incremental

# Check for configuration issues
python main.py config --validate
