Summary
As we conclude this chapter on telemetry in Go, we’ve journeyed through the essential practices and tools that illuminate the inner mechanics of Go applications, enhancing their observability. This exploration began with an in-depth look at logging, where we learned to transcend essential log messages, adopting structured logging for its clarity and ease of analysis. We then navigated the complex yet crucial world of tracing, uncovering the intricate execution paths of our applications to identify and resolve performance bottlenecks. Also, we ventured into metrics, where quantitative data measurement enabled us to monitor and tune our applications for optimal performance. Lastly, we combined all the knowledge in a vendor-free solution backed by OTel.
In the next chapter, we’ll start to look at how to distribute our apps.
