As the growth lead of an open-source APM tool, I keep interacting with developers from companies of all shapes and sizes. I recently talked with a developer from a fintech startup in India. The startup provides a payment processing platform that enables businesses to accept payments from customers worldwide. For them, monitoring is critical, but the dev shared how limited they were when exploring an APM tool for their application. The reason? Reserve Bank of India.

Nodejs is a popular Javascript runtime environment that executes Javascript code outside of a web browser. Express is the most popular web frameworks that sits on top of Nodejs and adds functionalities like middleware, routing, etc. to Nodejs. You can monitor your express application using OpenTelemetry and a tracing backend of your choice.

OpenTelemetry can auto-instrument many common modules for a Javascript application. The telemetry data captured can then be sent to SigNoz for analysis and visualization. OpenTelemetry is a set of tools, APIs, and SDKs used to instrument applications to create and manage telemetry data(Logs, metrics, and traces). For any distributed system based on microservice architecture, it's an operational challenge to solve performance issues quickly.

In this article, learn how to setup application monitoring for Node.js apps with our open-source solution, SigNoz. Node.js tops the list of most widely used frameworks by developers. Powered by Google's V8 javascript engine, its performance is incredible. Ryan Dahl, the creator of Node.js, wanted to create real-time websites with push capability. On Nov 8, 2009, Node.js was first demonstrated by Dahl at the inaugural European JSconf.

Welcome to our monthly product newsletter - SigNal 23! Last month, our team worked on improving the search capabilities across multiple tabs. We also made the logs tab more intuitive by adding color coding in the logs view. We presented SigNoz at an observability-focused meetup and crossed 12,000+ GitHub stars. Let’s dive in to see what humans at SigNoz were up to in the month of March 2023.

In modern microservices-based applications, it is difficult to get an overview of how requests are performing across multiple services, infrastructure, and protocols. As companies began moving to distributed systems, they realized they needed a way to track requests in their entirety for debugging applications. Distributed tracing is a technology that was born out of this need.
