Software Architecture in Golang: Observability
Observability is key when working on Distributed Systems, it allows us to understand the behavior of an application and troubleshoot problems.
Observability consists, among other things, in instrumenting services, collecting their metrics and saving their logs with the whole point of making sure all those 3 streams of data are connected in a sane way so we can use that information to learn about their behavior and understand what exactly is happening.
OpenTelemetry is the de-facto Open Source solution for Observability, together with well-known projects like Jaeger, Zap and Promethus it allows us to collect metrics and details regarding the flow of our services, how they communicate with each other, however keep in mind that at the time the Go support for OpenTelemetry is still in progress so may want to consider a few commercial options instead, like:
