OTEL Delta Temporality Support in Prometheus

Explore the evolution of OpenTelemetry delta metric support in Prometheus through this 28-minute conference talk that examines the historical challenges and recent progress in improving OTEL-Prometheus interoperability. Learn about the fundamental differences between OpenTelemetry's native support for both delta and cumulative temporality and Prometheus's traditional cumulative-only approach, which previously caused delta metrics to be rejected at the OTLP endpoint. Discover the technical journey behind implementing delta support in Prometheus, including the specific challenges encountered during development and the current state of this integration. Gain insights into the remaining open questions and potential future developments that could further enhance the compatibility between these critical cloud native monitoring technologies.
