In the last chapter of these series, we covered how to create your first Kibana dashboard for a sample web application.

Although that will help you setup Kibana for your production services, what you'll be doing 99% of the time would be to actually use the dashboard to monitor & debug issues you observe on production.

This is the final post in the series for monitoring Go applications \w Kibana. It will give you some practice using your newly created dashboard to identify problems with a sample web application.

So if you've setup Kibana for the first time or you've just joined your new team & seen your Kibana dashboards without a clue what's going on, this post is for you!

In this tutorial, I'll show you how to create a dashboard for your application's structured logs in Kibana.

This is a follow-up to this article, which covers how to instrument your Go application \w structured logging for use by Kibana (in this tutorial).

We'll use Kibana v7.6 but any version you're using should work. It's just that your UI might look a bit different & you'll have to adjust.

Let's jump straight in! We'll stick to simple panels, which suite most of the use-cases you'd need.

The Elastic stack (also referred to as ELK) can bring a lot of value to your production services. But it is not that much of value if you don't use structured logs in your services.

In one of my latest posts, I wrote about what ELK is and why you should care. I also wrote a tutorial about how to integrate ELK with your Go app.

In this article, I will walk you through how to integrate structured logging in your Go services. We will use a sample HTTP service with a few basic endpoints and we'll use the zap library to emit logs on error/success, which would also include some domain-specific info.

When you start developing your application, you typically instrument it with some logging to be able to debug problems later.

Some skip it in the development phase, but once the application hits production, then it is crucial to have some logging.

After all, once users complain that something isn't working, how would you be able to find the root-cause?

And although logging proves to be useful, many companies don't really capitalise on its potential as they're still clinging to the classic way of writing freestyle logs and grep-ing them on their prod machines afterwards.

However, there is so much more potential that logging holds for monitoring our production systems. In this article, I will show you how to get the maximum value from your logs using the ELK stack.
