In a world of microservices, distributed systems, and ever-growing complexity, understanding what your Python applications are doing under the hood is no longer a luxury—it’s a necessity. This talk introduces OpenTelemetry, the CNCF project that is fast becoming the global standard for observability.

We’ll explore how to instrument Python applications with OpenTelemetry to capture traces, metrics, and logs, and how to export this data to popular backends like Prometheus, Jaeger, or Elastic. Whether you're building a Flask API or a machine learning pipeline, you'll leave this talk understanding how observability can help you debug faster, monitor better, and sleep easier. All these, relying on an open-source, community driven project without the fear of vendor lock-in.

We will wrap up the session with a live demo, putting into action OpenTelemetry + Python.
