How we improved observability into our Rust based services with the help of the tracing crate. The talk will share insights that can help you understand your options for building more observable systems. We’ll cover the lessons learned during our journey, offering takeaways that apply not only to services written in Rust, but to writing more observable and maintainable code in any language. These insights aim to help developers proactively solve problems, avoiding the common frustration of searching for a "needle in the haystack" during debugging or incident resolution.
