It’s no secret that developers are increasingly being asked to shift left. It seems there’s always something new to shift left on. And now developers are being asked to shift left on observability. This means that in addition to all the other things developers must do, they must also take the extra step of instrumenting their application code with OpenTelemetry, to help make it observable.

This seems needless. It’s extra work. Why should developers care about observability? After all, isn’t observability the domain of SREs? Additionally, what’s the point of adding instrumentation to application code if it only seems to benefit SREs?

What’s in it for developers?

How does observability help developers?

If you’re being asked to instrument code, you may be thinking: how much extra time will this add to my workload? After all, application instrumentation involves adding traces, logs, and metrics to your code, making it more observable. This means more code to maintain, introducing complexity, bugs, and technical debt.

While that’s true, let’s look at how observability benefits developers.

1. It reduces debug time

Nobody loves spending hours and hours trying to chase down a nasty bug.

2. It accelerates development and deployment

Faster debugging means that developers can finish working on a feature faster and ship it faster.

3. It improves your code

Instrumenting code can expose slow paths, hidden retries, and weird edge cases which can be addressed before the code ever hits production.

4. It helps us understand distributed systems

Micro services are everywhere, and …
