Exposing More Public Endpoints for Sending Metrics and Errors to AppSignal

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.

The Easiest Way to Monitor Ruby: Automatic Instrumentation

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.

Powerful Caching with Redis for Node.js Applications

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.

New Feature: Searching Through Samples in AppSignal

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.

Improving Node.js Application Performance With Clustering

When building a production application, you are usually on the lookout for ways to optimize its performance while keeping any possible trade-offs in mind. In this post, we’ll take a look at an approach that can give you a quick win when it comes to improving the way your Node.js apps handle the workload. An instance of Node.js runs in a single thread which means that on a multi-core system (which most computers are these days), not all cores will be utilized by the app.

AppSignal for Elixir Integration 2.1 Released

We’re happy to announce the release of AppSignal for Elixir 2.1.0. 🥳 In this version, we’ve made our error helpers more flexible than before. You could already send Elixir exceptions directly through AppSignal and now you can add extra metadata to errors when using send_error/2-4. Let’s go through all of the changes 😀
