The concept of observability has been around for decades, but it’s a relative newcomer to the world of IT infrastructure. So what is observability in this context? It’s the state of having all of the information about the internals of a system so when an issue occurs you can pinpoint the problem and take the right action to resolve it.
Notice that I said state. Observability is not a tool or a set of tools — it’s a property of the system that we are managing.
