Today, we launch a new feature: sending metrics and errors to AppSignal over our “Public Endpoint” API. AppSignal has many web frameworks, databases and background job frameworks automatically instrumented when you want to monitor a Node.js, Ruby or Elixir app. If you have code running on serverless architecture such as AWS Lambda, you can’t run our agent, so our standard integration with all of the out-of-the-box magic won’t work.

In today’s post, we’ll dive into how we, at AppSignal, solved a daunting engineering challenge. Giving you a look into the kitchen, this post will show you how we tested a new database in production without having to worry about errors/downtime. Alright, let’s get cooking!

Setting up a proper monitoring overview over your application’s performance is a complex task. Normally, you’d first need to figure out what you need to monitor, then instrument your code, and finally make sense of all the data that has been emitted. However, with a few things set in place, and an APM that natively supports Ruby, it’s easier than ever to take this step. In this post, we’ll show you how you can do it too.

Regardless of the tech stack used, many developers have already used Redis or, at least, heard of it. Redis is specifically known for providing distributed caching mechanisms for cluster-based applications. While this is true, it’s not its only purpose. Redis is a powerful and versatile in-memory database. Powerful because it is incredibly super fast. Versatile because it can handle caching, database-like features, session management, real-time analytics, event streaming, etc.

Your wishes are being granted. Search is now available for all AppSignal customers. 🎉 You can now quickly find specific samples inside of AppSignal. This is especially useful when searching for an error/slow request for a particular customer in a specific revision or request ID. You can access the search in AppSignal from any screen in an application. It’s located in the dark top bar. Let’s take a look at the new search in action.

We’re very happy to present you with version 3.0 of AppSignal for Ruby - a new major release for the Ruby gem. 🎉 We have changed the way we instrument apps and gems to provide better compatibility with other instrumentation gems. Support for Ruby version 1.9 has been removed and deprecated classes, modules, methods, and instrumentations have also been removed. Read our upgrade guide! In the rest of the post, we’ll explain what the new version of our gem brings to you and your apps.
