The Observant Developer — Part 1
Like tests, observability tools provide a way for developers to validate code assumptions, without the added cement.
I was debating which type of example to include with these posts. However, I was absolutely sure what I did not want to write about — setup. There are numerous tutorials and blog posts that do a great job explaining how to set up observability tools and OpenTelemetry in particular. This is not a very interesting topic or one where I have much to contribute. I’ll be sure to include links to the existing guides and tutorials.
What I do want to focus on, however, is how to make observability useful. After setting up a basic stack, how do we get useful insights and measurements to use in the coding day-to-day? What can I glean from a trace visualization like this one?
