Today's software is significantly more complex than it was 20+ years ago, making troubleshooting increasingly challenging. However, implementing observability into systems has helped in understanding application performance and identifying issues. Observability for CI/CD pipelines has not progressed as much as expected, despite their importance in the software delivery process. OpenTelemetry is an open-source observability framework that provides a set of APIs, SDKs, instrumentation libraries, and tools to help generate, collect, transform, and export telemetry data. It offers freedom from vendor lock-in and provides useful tools such as the Collector, which ingests, transforms, and exports data to one or more observability backends. Observability for CI/CD pipelines is crucial for troubleshooting issues, achieving development agility, and gaining insights into pipeline health. While OpenTelemetry is a promising solution, there are challenges in standardization, tooling landscape disorganization, and limited adoption by popular CI/CD tools.
