OpenTelemetry SDK: Concepts & Design | HackerNoon
Briefly

OpenTelemetry provides a vendor-neutral, tool-agnostic observability framework, allowing for seamless collection of traces, metrics, and logs across diverse systems.
The rise of the open source community has shifted preferences from proprietary protocols to community-recognized open source projects like OpenTelemetry for observability.
To fully address the pillars of observability—logs, metrics, and traces—businesses must often combine multiple collectors and protocols, each potentially complicating the integration process.
Despite open source solutions, individual protocols can create dependency issues, making it challenging for applications to switch between different collectors or storage options.
