Yesterday I was told that I had to investigate an issue on production that affected our end user using our web front end and was throwing a ton of exceptions. I didn’t know how to get that data until a colleague pointed me to a table which recorded our exceptions. After he showed me the table I could see the most common exceptions by fetching and grouping by the StackTrace. This made me wonder if there was a way to make this information available to the developers in a more transparent way and I found out about Gitlab’s Error Tracking page.

Basically it uses Sentry as the backend and requires you to setup an instance of Sentry or use Sentry.io SAAS solution.

I’m currently trying to build a Sentry infrastructure on my Kubernetes cluster currently but I’m having issues deploying it because something related to the DB migration isn’t working 🤷🏻‍♂️

Once I finish the deployment, I’m planning to start sending some events to it and checking how it works so we can use it in our infrastructure. This allows a lot of value to our error reporting and make the devs more aware of the exceptions happening on production.
