Retrofitting OpenTelemetry into existing applications follows a phased migration approach spanning six independently deployable phases. It starts with SDK initialization and progresses to instrumenting HTTP middleware and bridging existing logging and Prometheus metrics.

Yes, you can bridge existing Prometheus metrics and logging systems with OpenTelemetry. The migration provides specific instructions for integrating existing logging and metrics systems to coexist with OTel.

The best way to refactor function signatures for trace context threading is using language-specific strategies. These strategies help thread trace context through complex call chains while integrating framework middleware for proper context propagation.

Yes, retrofitting observability requires understanding language-specific context propagation mechanisms. This knowledge is necessary to refactor function signatures for trace context threading and integrate framework middleware effectively.

To instrument HTTP middleware during an OpenTelemetry migration, follow the phased deployment guide. This process integrates OTel into your application's request handling flow without disrupting current logging or metrics systems.
