NestJS is a popular framework for Node.js that allows you to build efficient and scalable backend applications. With AppSignal, you can monitor your NestJS app with ease and rely on OpenTelemetry to handle third-party instrumentations. AppSignal even provides helper functions to help you build comprehensive custom instrumentations. This article aims to help you get the most out of your AppSignal integration.

After a period of beta testing, we're happy to announce the launch of our latest AppSignal for Node.js package. This package features six new integrations and uses the OpenTelemetry framework for reliable telemetry data collection. OpenTelemetry is an open standard that facilitates the instrumentation of standardized telemetry data collection. AppSignal is committed to using OpenTelemetry in new integrations, and our Node.js integration is the first to use the standard.

AppSignal is a strong supporter of open-source technology. We owe so much of our modern world to the unseen, hard-working software developers who build and maintain the many technologies that make everything from reading this article to sending a message from your phone possible. That's why we're investing in OpenTelemetry, the open-source standard for telemetry data collection, rather than developing our own independent standard.

AppSignal for Elixir now provides out-of-the-box support for Finch. If your Elixir app sends requests to another web app, you're likely already using Finch. We wanted to ensure that AppSignal's analytics provided performance data on a per-request level.

Application teams must understand what their customer experience is like. This is true not only from a general perspective (in terms of usability and responsiveness) but also on a day-to-day, minute-by-minute basis. In particular, when you work with distributed systems, errors are inevitable. Site traffic fluctuates throughout the day, and any one of a system’s dependencies could also encounter an issue at any time.

Today, we're launching ARM support for machines running Alpine Linux. This feature is available for our Ruby and Elixir users! We hope to add support for Alpine Linux ARM to our Node.js package in the future. The ARM CPU architecture is becoming more and more popular. As it powers people's development machines and production servers, we decided to add it to the list of the operating systems we support.

We're very excited to release AppSignal for Ruby gem 3.1, which adds a Magic Dashboard for MRI VM stats. By upgrading to the latest Ruby gem, you'll automatically get this dashboard created in AppSignal as soon as data from the new probe starts flowing in. Here's what you'll see: Magic Dashboards give people amazing insights into applications with zero setup. They work automagically to give your team performance insights into gems like Puma, Sidekiq, ActiveJob, ActionMailer, and others.

AppSignal helps you separate signal from noise. Today, we're launching a new notification setting that will help you get the right notifications at the right time.

Today we launch the next level of AppSignal front-end error tracking. We’ve made two major improvements: line-of-code-based error grouping and sourcemapped backtraces in notifications.

We're very excited to release AppSignal for Phoenix 2.1, which adds automatic instrumentation for LiveView through Telemetry. You can now receive performance and error insights for your LiveView, without manually instrumenting each of its methods.
