Monitoring SAP Cloud Foundry Applications with Prometheus and Python

Yogananda — Sat, 08 Aug 2026 06:15:43 GMT

Running applications on SAP BTP Cloud Foundry is easy, but operating them efficiently requires good observability. One of the most popular approaches is exposing application metrics using Prometheus and visualizing them with tools such as Grafana.

In this blog, we'll build a simple Python application that exposes Prometheus metrics and deploy it to SAP Cloud Foundry using a manifest.yml.

Why Prometheus?

Prometheus provides:

Real-time monitoring
Application health insights
Custom business metrics
Alerting integration
Grafana dashboard support

For SAP Cloud Foundry applications, exposing a /metrics endpoint allows Prometheus to scrape key runtime statistics.

Battery

pip install flask prometheus-client

Sample Application

from flask import Flask from prometheus_client import Counter, generate_latest app = Flask(__name__) request_counter = Counter( "app_requests_total", "Total number of requests" ) @app.route("/") def home(): request_counter.inc() return "Hello SAP Cloud Foundry!" @app.route("/metrics") def metrics(): return generate_latest(), 200, { "Content-Type": "text/plain" } if __name__ == "__main__": app.run(host="0.0.0.0", port=8080)

Requirements File

flask prometheus-client gunicorn

Manifest

applications: - name: prometheus-python-demo memory: 256M disk_quota: 512M instances: 1 buildpacks: - python_buildpack command: gunicorn app:app routes: - route: prometheus-python-demo.cfapps.eu10.hana.ondemand.com health-check-type: port env: PYTHONUNBUFFERED: "true"

Deploy to Cloud Foundry

cf login --sso cf push cf apps

Best Practices for SAP Cloud Foundry

Expose only the /metrics endpoint.
Avoid exposing sensitive business data.
Use HTTPS routes.
Monitor memory and instance count.
Add custom metrics for business KPIs.
Integrate Prometheus with Grafana dashboards.
Use alerting rules for application failures.

Conclusion

By combining Python, Prometheus, and SAP Cloud Foundry, you can quickly establish a lightweight monitoring solution. Exposing application metrics through a /metrics endpoint and deploying with a simple Cloud Foundry manifest.yml provides a solid foundation for operational visibility and proactive monitoring on SAP BTP.
