🔴 High Priority (Immediate Actions)

Cloudflare Tunnel

• Monitor Cloudflare tunnel metrics for patterns and connection issues
• Investigate network latency between Cloudflare edge and origin
• Review Cloudflare tunnel configuration for potential issues
• Consider increasing Cloudflare tunnel connection pool size

Web3Signer Configuration

• Import signing keys to Web3Signer service (VMID 107)
• Configure Web3Signer key management policies
• Test transaction signing via RPC Translator
• Document Web3Signer key rotation procedures
• Set up Web3Signer key backup procedures

---

🟡 Medium Priority (Short-term)

Monitoring & Observability

• Configure monitoring for success rate trends over time
• Set up tracking for response time patterns and anomalies
• Configure alerts for service downtime (RPC Translator, Besu, Nginx)
• Set up monitoring for Cloudflare tunnel health status
• Track error rates by endpoint and RPC method
• Monitor system resource usage (CPU, memory, disk) with alerts
• Set up alerts for Besu sync issues and block height problems

Health Check & Metrics

• Add /metrics endpoint for health check metrics

Error Logging

• Implement logging for all 502 errors with full request context
• Track error patterns and timing (time-based analysis)
• Correlate errors with system metrics (CPU, memory, network)
• Add request ID tracking for error correlation
• Log Cloudflare tunnel errors separately from application errors
• Add error rate metrics and trending
• Implement error categorization (502, timeout, connection, etc.)

Security & Configuration

• Identify authorized wallet addresses for production
• Add wallet addresses to WALLET_ALLOWLIST in .env files
• Update Vault configuration if using dynamic allowlist
• Test transactions from allowed addresses (verify success)
• Test transactions from non-allowed addresses (verify rejection)
• Document wallet allowlist management procedures
• Configure Redis password authentication on VMID 106
• Update REDIS_PASSWORD in .env files on all translator VMIDs
• Test Redis connectivity with password authentication
• Update connection strings in translator configuration
• Document Redis password management and rotation procedures

🟢 Low Priority (Long-term)

Metrics Collection

• Set up metrics collection system (Prometheus/Grafana recommended)
• Track RPC request rates by method (eth_chainId, eth_sendTransaction, etc.)
• Monitor response times (p50, p95, p99 percentiles)
• Track error rates by type (502, timeout, validation errors)
• Monitor transaction success rates for eth_sendTransaction
• Track nonce management metrics (locks, conflicts, retries)
• Monitor Web3Signer signing times and success rates
• Track Redis connection health and operation metrics

Log Aggregation

• Set up centralized log aggregation system
• Configure log rotation and retention policies
• Implement structured logging (JSON format)
• Add log correlation IDs for request tracing
• Set up log search and analysis tools

Load Testing

• Design load testing scenarios for concurrent RPC requests
• Test concurrent request handling (100, 500, 1000 concurrent)
• Test high transaction volumes with eth_sendTransaction
• Identify bottleneck points under load (translator, Besu, Redis)
• Measure response times under various load conditions
• Test Redis nonce locking under concurrent transaction load
• Document maximum concurrent connections and capacity limits

High Availability

• Set up secondary Cloudflare tunnel endpoint
• Configure load balancing between multiple tunnel endpoints
• Implement automatic failover between tunnel endpoints
• Configure DNS for multiple tunnel endpoints
• Test failover scenarios and recovery procedures

Alternative Access

• Design direct IP access solution for trusted clients
• Set up VPN or private network access option
• Configure alternative routing paths bypassing Cloudflare
• Implement authentication for direct access
• Document direct access procedures and setup

WebSocket Support

• Configure Nginx for WebSocket upgrade (proxy_set_header Upgrade, Connection)
• Update RPC Translator to handle WebSocket connections
• Test WebSocket endpoint functionality and subscriptions
• Verify WebSocket subscriptions work correctly
• Test WebSocket under load conditions
• Document WebSocket usage and API

Documentation

• Create operational runbook for common tasks and procedures
• Write incident response procedures and escalation paths
• Create disaster recovery plan and procedures
• Document capacity planning guide and scaling procedures
• Enhance troubleshooting guide with common issues and solutions
