Koabamm! We now monitor Koa. This Node.js framework enables you to use cascading middleware, which can now also be shown in AppSignal. Let’s dive right in!

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.

ActiveRecord is Ruby on Rails’ most magical feature. We don’t usually need to worry about its inner workings, but when we do, here’s how AppSignal can help us know what’s going on under the hood.

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.

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 😀

Made for teams that want to build high quality Ruby and Elixir applications, AppSignal offers amazing insights into errors and performance issues, plus host monitoring and an easy to use custom metrics platform.

AppSignal supports the Elixir language with an Elixir package. The package supports pure Elixir applications and frameworks including Phoenix, Plug & Erlang.

AppSignal supports the Ruby language with a Ruby gem. The gem supports many frameworks and gems including Capistrano, DataMapper, Delayed Job, Grape, MongoDB, Padrino, Rack, Rake, Resque, Ruby on Rails, Sequel, Shoryuken, Sidekiq, Sinatra & Webmachine.

AppSignal now supports Node.js! The package supports pure JavaScript applications and TypeScript applications, and can auto-instrument various frameworks and packages with optional plugins.

AppSignal also has amazing support for catching errors from Front-end JavaScript applications and sending them to AppSignal, including the React, Vue, Angular, Ember, Preact & Stimulus frameworks.

Packed with features:

  • Alerts in your tools: AppSignal integrates with Slack, Flowdock, HipChat, OpsGenie and more.
  • Control your notifications: AppSignal notifies you exactly when you want to. Get the first exceptions per deploy, all of them of never. Set thresholds for performance notifications.
  • Amazing support: We don't do "first line" and "second line" support: you get to speak with a developer, immediately.
  • Send to issue trackers: A single click creates an issue with all the necessary details in your issue tracker of choice.
  • Manage teams and users: Add users to teams and give them access to specific or all, existing and/or new applications you monitor.
  • Focus on design: Developer tools do not need to be complicated and ugly. Our interface is kept clean and easy to use.

Catch errors, track performance, monitor hosts, detect anomalies — all in one tool.
