As we're doing our best to make monitoring easy, we've wanted to make more content that would really show and not just tell you how easy it is to set up monitoring with AppSignal.

We've been collaborating with Leigh Hallday on making this video for you that will show you everything you need to know about the setup process. We'll be posting more videos like this on our YouTube channel, so you should subscribe to it if you'd like to get notifications about future videos. You know how that works 😉

What's In the Video

In this video, Leigh will show you how easy it is to integrate AppSignal into a Rails application. He covers installation and setup, how to troubleshoot and fix performance issues, specifically showing a common use-case with N+1 queries.

The N+1 query anti-pattern happens when a query is executed for every single result of a previous query. The query count is N + 1, where N is the number of queries for every result of the initial query. Now if that initial query has one result, then N+1 = 2. If it has 1000 results, N+1 = 1001 queries 🙀. It's easy to spot them, Leigh will show you how.

He'll then show you AppSignal's Sidekiq integration along with its magic dashboard, which can really help pinpoint performance issues. The whole process is automated as Sidekiq is detected during setup, and things like throughput, duration per job and queue length are plotted on their own graphs. That way you can see when peak, and set up alerting and fix issues with as little work as possible.
