Monitoring

Health Checks

typescript
// NestJS Terminus for health checks
@Controller("health")
export class HealthController {
  constructor(
    private health: HealthCheckService,
    private db: PrismaHealthIndicator,
  ) {}

  @Get()
  check() {
    return this.health.check([() => this.db.pingCheck("database")]);
  }

  @Get("ready")
  ready() {
    return this.health.check([
      () => this.db.pingCheck("database"),
      // Add pg-boss check
    ]);
  }
}

Simple Logging Strategy

typescript
// Structured JSON logging with Pino
{
  "level": "info",
  "time": "2024-01-15T10:30:00Z",
  "requestId": "abc-123",
  "userId": "user-456",
  "action": "commission.calculated",
  "data": { "amount": 150.00, "partnerId": "partner-789" }
}

Production Monitoring Stack

  • Metrics: Prometheus + Grafana (self-hosted) or Datadog
  • Logs: Structured JSON to CloudWatch Logs or Loki
  • Alerts: Grafana Alerting or PagerDuty for critical thresholds
  • Tracing: Correlation IDs in all requests for debugging multi-layer operations
