Many of us are impacted in one way or another by the Covid-19 virus. At AppSignal, we asked our team to prioritize their families and (mental) health first. We hope you were able to do the same. We are starting to find a new rhythm in these uncertain times, and are continuing on our mission to bring developers amazing monitoring. In that light, we are happy to ship the first version of AppSignal for Node.js.
Ruby has always been known for the productivity it brings to its developers. Alongside features such as elegant syntax, rich meta-programming support, etc. that make you productive when writing code, it also has another secret weapon called TracePoint that can help you “debug” faster. In this post, I’ll use a simple example to show you 2 interesting facts I found out about debugging.
If you have some experience setting up monitoring for different setups, this post is for you. Since different parts of your architecture have different tasks, they also have different expectations. Today, we’ll take a quick dive into how to deal with that reality and set up monitoring for it. Warning: In this post, you’ll have to bear with our enthusiasm for setting things up perfectly.
In today’s post, we’ll learn what gRPC is, when you should reach for such a tool, and some of the pros and cons of using it. After going over an introduction of gRPC, we’ll dive right into a sample application where we’ll build an Elixir backend API powered by gRPC. Let’s jump right in!
In today’s post, we will be looking into a software design pattern called Facade. When I first adopted it, it felt a little bit awkward, but the more I used it in my Rails apps, the more I started to appreciate its usefulness. More importantly, it allowed me to test my code more thoroughly, to clean out my controllers, to reduce the logic within my views and to make me think more clearly about an application’s code’s overall structure.
Elixir 1.10 was recently released, and with that release came a little-known, but very interesting feature—compiler tracing. This feature means that as the Elixir compiler is compiling your code, it can emit messages whenever certain kinds of things are compiled. This ability to know what’s going on when Elixir is compiling our code might seem simple, but it actually opens up a lot of doors for opportunities to build customized compile-time tooling for Elixir applications.
In today’s post, we’ll learn how to build a Rails app that can support multiple subdomains. Let’s assume that we have a gaming website funkygames.co and we want to support multiple subdomains such as app.funkygames.co, api.funkygames.co, and dev.funkygames.co with a single Rails application. We want to ensure that proper authentication is performed for all subdomains and that there are no duplicate routes.
Great news for all the Elixir alchemists, we’ve just released AppSignal for Elixir package version 1.12.0 which adds support for the upcoming 1.5 version of the Phoenix framework, and improves in-channel error handling. If you’re not an AppSignal user yet, make sure to check out the product tour and see how errors, performance, host metrics and triggers all come together in one tool. Phoenix 1.5 isn’t here yet, but AppSignal 1.12 is ready for it.
Today, we’re introducing a small but useful change to the Anomaly detection that configures which hosts the host triggers should listen to. Do you have a stroopwafel in your hand? Yes? Then let’s dig in.
Today, we’re bringing you an update of the performance/exceptions sample page. This update includes a number of improvements that will help you navigate and filter the available samples faster and more smoothly. We’re bringing these changes as an iteration of sample navigation improvements that we launched a while ago. We received valuable feedback from our users: the overlay made the navigation choppy instead of fluent.
