Summary
In this chapter, we have looked at different ways of adding log functionality to applications. We also learned about the golog library, which provides more flexibility and features than the standard library can offer. We looked at creating our own simple logging server that enables our application to send log information that can be used in a multi-service environment.
In the next chapter, we will look at how to add observability functionality to applications. We will look at tracing and metrics and go through the OpenTelemetry specification.
