Mario Macias
After falling in love with programming at age 12, Mario has spent 20 years in software engineering, as a scientific researcher, PhD student, university teacher, backend developer, and book writer. During the last 7 years Mario has been focused on monitoring and observability at different layers.
Session
This beginner-friendly, three-hour hands-on workshop guides developers and SREs through instrumenting applications using OpenTelemetry and exporting telemetry data (metrics, logs, and traces) to the Grafana LGTM stack. Participants will explore various instrumentation approaches—including code-level OpenTelemetry SDKs, infrastructure metric collection via the Collector, and zero-code eBPF instrumentation for cross-service communication—alongside optimization techniques like span sampling and metrics tuning. By the end of the session, attendees will gain a clear, practical roadmap for implementing and customizing scalable observability patterns within their own Docker-based environments.
