- Add CloudWatch metrics emitter (api_latency, api_requests, api_errors) - Add request monitoring middleware for API (latency, error rate, throughput) - Register error-handling, logging, and monitoring middleware in server.ts - Add Datadog log forwarding via HTTP intake API - Add application-level CloudWatch alarms for P99 latency, error rate, throughput - Inject Datadog/Sentry env vars and secrets into ECS task definitions - Add DD_API_KEY and SENTRY_DSN to ECS secrets - Create CloudWatch log groups for datadog and sentry services - Update .env.example with AWS_REGION and monitoring variables - Add @aws-sdk/client-cloudwatch dependency to monitoring package Co-Authored-By: Paperclip <noreply@paperclip.ing>
