How to Monitor Scaleway Infrastructure with Vigilmon

Scaleway is Europe's leading cloud provider, offering compute instances, object storage, managed databases, container registries, and serverless functions — all at competitive prices. Whether you're running a single VPS or a multi-region Kubernetes cluster, monitoring your Scaleway infrastructure is critical for reliability.

This guide shows you how to monitor Scaleway-hosted applications using Vigilmon.

What to Monitor on Scaleway

Resource What to check
Instances (DEV1, GP1, etc.) HTTP availability, response time
Managed databases App-level DB health check
Kubernetes (Kapsule) Ingress endpoint availability
Serverless Functions HTTP endpoints
Load Balancers LB endpoint HTTP check
Object Storage (S3-compatible) API endpoint availability

Step 1: Monitor Your Scaleway Instance

For any application running on a Scaleway instance, add a health endpoint to your app (see framework-specific guides for Node.js, Python, Go, etc.) and then register it in Vigilmon.

Example for a simple Node.js app on a Scaleway DEV1-S:

// server.js
const http = require('http');

const server = http.createServer((req, res) => {
  if (req.url === '/health') {
    res.writeHead(200, { 'Content-Type': 'application/json' });
    res.end(JSON.stringify({ status: 'ok', timestamp: Date.now() }));
    return;
  }
  // ... your app logic
});

server.listen(3000, '0.0.0.0');
Enter fullscreen mode Exit fullscreen mode

In Scaleway's console, ensure port 3000 (or 80/443) is allowed in your Security Group.

Step 2: Monitor Scaleway Managed Database

Vigilmon can't connect directly to a Scaleway managed PostgreSQL or MySQL — but your application can report database health:

# Flask example on Scaleway
from flask import Flask, jsonify
import psycopg2
import os

app = Flask(__name__)

@app.route('/health')
def health():
    try:
        conn = psycopg2.connect(os.environ['DATABASE_URL'])
        conn.close()
        return jsonify({'status': 'ok', 'db': 'ok'})
    except Exception as e:
        return jsonify({'status': 'error', 'db': str(e)}), 503
Enter fullscreen mode Exit fullscreen mode

Step 3: Monitor Scaleway Kubernetes (Kapsule)

For Kubernetes clusters on Scaleway Kapsule, monitor your ingress endpoint:

# k8s/healthcheck-deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp
spec:
  template:
    spec:
      containers:
      - name: myapp
        image: rg.nl-ams.scw.cloud/myorg/myapp:latest
        livenessProbe:
          httpGet:
            path: /health
            port: 8080
          periodSeconds: 30
        readinessProbe:
          httpGet:
            path: /health
            port: 8080
          periodSeconds: 10
Enter fullscreen mode Exit fullscreen mode

Then register your Kapsule Load Balancer IP or domain in Vigilmon:

  • URL: https://your-kapsule-lb.k8s.fr-par.scw.cloud/health
  • Expected status: 200

Step 4: Monitor Scaleway Serverless Functions

Scaleway Serverless Functions get a unique HTTPS URL. Monitor it directly:

https://your-function.functions.fnc.fr-par.scw.cloud
Enter fullscreen mode Exit fullscreen mode

Add a health-check namespace to your function:

# handler.py
def handle(event, context):
    if event.get('path') == '/health':
        return {
            'statusCode': 200,
            'body': '{"status": "ok"}'
        }
    # ... main function logic
Enter fullscreen mode Exit fullscreen mode

Step 5: Add Monitors in Vigilmon

  1. Sign up at vigilmon.online
  2. For each Scaleway resource, add an HTTP Monitor:
    • Instance: http://YOUR_IP:PORT/health
    • Load Balancer: https://your-lb-domain/health
    • Serverless Function: https://your-fn.scw.cloud/health
  3. Set check interval: 1 minute
  4. Configure alerts: email + Slack (or webhook to your incident system)

Monitoring Multiple Scaleway Regions

Scaleway offers regions in Paris (fr-par), Amsterdam (nl-ams), and Warsaw (pl-waw). If you're running multi-region:

  • Add a monitor per region endpoint
  • Use Vigilmon's multi-location checking to detect region-specific outages
  • Compare response times across regions

Conclusion

Scaleway's European cloud infrastructure powers thousands of startups and enterprises. Vigilmon gives you simple, reliable external monitoring for any Scaleway-hosted workload — no agent required, no complex configuration.
