OpenTelemetry is an open-source project that provides a unified framework for collecting, processing, and exporting observability data from distributed systems. Observability data includes metrics, traces, and logs that help developers and operators understand the behavior and performance of their applications.
For example, serverless functions have short lifespans and may not have access to persistent storage or network resources. This means traditional methods of collecting and exporting observability data, such as using agents or sidecars, may not work well for serverless functions. Additionally, serverless functions may have complex invocation patterns and dependencies, which make it difficult to trace the end-to-end execution flow and identify bottlenecks or errors.
