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
]);
}
}Key Metrics to Track
| Metric | Source | Alert Threshold |
|---|---|---|
| API response time (p95) | Application logs | > 2s |
| Failed jobs count | pg-boss archive | > 10/hour |
| Commission processing lag | Job queue age | > 5 min |
| Database connections | PostgreSQL | > 80% pool |
| Error rate (5xx) | HTTP logs | > 1% |
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
