Observability can help you understand change – but it won’t replace monitoring

Observability has become a hot topic in reliability engineering and DevOps. But if you ask four different engineers what it means, you will probably get four different definitions. In this talk, I’ll cover the definition that I think is most useful as part of managing distributed systems: observability is the practice of understanding change in software systems. I’ll talk about the building blocks of observability, give some examples, and also relate it to the time-tested practice of monitoring production systems. While it may be tempting to think that new tools obviate the need to monitor systems, I’ll argue that there are some aspects monitoring that are here to stay. At the end of this talk, you’ll have a better sense of the value of the tools that you already have and some ideas as to when you should consider expanding your toolbox.
