PROFILE
Lubos Mjachky
Worked on the pulpcore repository to overhaul telemetry by replacing built-in OpenTelemetry metrics with a custom middleware solution, introducing an OTEL_ENABLED feature flag to allow opt-in observability across API and content services. The approach included removing CI-based OpenTelemetry tests to streamline continuous integration and updating documentation for improved developer onboarding. Using Python, Django, and configuration management skills, addressed a reliability issue in artifact size metrics reporting by ensuring accurate counter increments regardless of caching state. These changes enhanced system monitoring, analytics accuracy, and capacity planning, while reducing CI maintenance and clarifying operational workflows for developers working with pulpcore.

Oct 1, 2024October 2024: Implemented a telemetry overhaul in pulpcore by replacing built-in OpenTelemetry metrics with a custom instrumentation middleware across API and content services, and introducing an OTEL_ENABLED opt-in flag (default false). Removed CI-based OpenTelemetry tests to reduce CI burden and improve pipeline stability. Documentation updated to reflect the new telemetry configuration and usage. Business value: improved observability with opt-in telemetry, reduced CI maintenance, and a clearer developer workflow; technical achievements include middleware instrumentation design and feature flag implementation.
