How to Monitor AWS Elastic Beanstalk with Vigilmon

AWS Elastic Beanstalk abstracts infrastructure management but does not eliminate downtime risk. Deployments can fail, auto-scaling events cause brief outages, and environment health can degrade silently. This guide shows how to monitor Elastic Beanstalk with Vigilmon.

Why Elastic Beanstalk Needs External Monitoring

Beanstalk built-in health monitoring has critical gaps:

  • Health checks run from inside AWS, not from your users' locations
  • CloudWatch alarms do not verify actual HTTP responses
  • Deployment failures may leave degraded states without clear signals
  • Load balancer health checks test internal connectivity only

Create a Health Check Endpoint

Node.js / Express:

app.get('/health', (req, res) => {
  res.json({ status: 'ok', env: process.env.NODE_ENV });
});
Enter fullscreen mode Exit fullscreen mode

Python / Flask:

@app.route('/health')
def health():
    return jsonify({'status': 'ok'}), 200
Enter fullscreen mode Exit fullscreen mode

Java / Spring Boot:

@GetMapping("/health")
public ResponseEntity<Map<String, String>> health() {
    return ResponseEntity.ok(Map.of("status", "ok"));
}
Enter fullscreen mode Exit fullscreen mode

Setting Up Vigilmon Monitors

Monitor 1: Application Health

  • URL: https://your-beanstalk-url.com/health
  • Method: GET
  • Expected status: 200
  • Keyword check: ok
  • Interval: 60 seconds
  • Multi-region: Enabled

Monitor 2: SSL Certificate

  • URL: https://your-domain.com
  • SSL expiry alert: 30 days before expiration

Monitoring Deployments

During rolling deploys, Vigilmon detects 502/503 responses during instance rotation. If deployment fails, Vigilmon alerts immediately before Beanstalk rolls back.

Strategy: Set consecutive failures = 3 during deploy windows, tighten to 1 for normal operation.

Environment Health Mapping

Beanstalk Health HTTP Response Vigilmon Detection
Green 200 Up
Red 500/503 Down - alert fires
No data Timeout Down - alert fires

Multi-Region Benefits

Vigilmon checks from multiple regions simultaneously, catching:

  • Regional AWS outages
  • CDN routing issues preventing users in certain regions from connecting
  • DNS propagation failures after environment rebuilds

Best Practices

  1. Create a /health endpoint with no auth required
  2. Monitor your custom domain URL, not just the Beanstalk URL
  3. Set 30-second timeout for scale-up events
  4. Check the Vigilmon dashboard during every deployment
  5. Use multi-region to catch regional AWS incidents

Conclusion

Vigilmon fills the gap between Beanstalk internal health checks and real user experience, with external HTTP monitoring and instant alerts.
