Monitoring your Nextjs application using OpenTelemetry

Nextjs is a production-ready React framework for building single-page web applications. It enables you to build fast and user-friendly static websites, as well as web applications using Reactjs. Using OpenTelemetry Nextjs libraries, you can set up end-to-end tracing for your Nextjs applications. Nextjs has its own monitoring feature, but it is only limited to measuring the metrics like core web vitals and real-time analytics of the application.

An Easy Guide to Getting Started with Elastic APM

Code in production will break. Maybe a request takes too long, maybe it fails quietly, or maybe it works fine one minute and falls over the next. Logs can help, sure—but they don’t always show the full picture, especially when performance issues are involved. Elastic APM gives you a clearer view. It traces what your application is doing from incoming requests to database queries and everything in between.

CI/CD Observability with OpenTelemetry - A Step by Step Guide

In the fast-paced world of CI/CD, understanding the performance and behaviour of your pipelines is crucial. GitHub Actions has become a popular choice for automating builds and deployments, but anyone who's debugged a flaky workflow or long-running job knows how challenging it can be to get visibility into what's happening under the hood. We usually rely on build logs, timing data, or guesswork when something goes wrong.

Top 13 Open Source APM Tools [2025 Guide]

Choosing the right APM tool is critical. How do you know which is the right one for you? Here are the top 13 open-source application performance monitoring(APM) tools that can solve your monitoring needs. Open-source APM tools have added benefits over their SaaS counterparts. They are more transparent, as you can verify their source code, and you can use them without going through the pains of obtaining approvals usually required for using a third-party vendor tool.

Top 15 Distributed Tracing Tools for Microservices in 2025

In one of our previous blogs, we discussed distributed tracing in depth. We examined why distributed tracing is critical and its components - spans and trace context. You can check the complete guide here: What is Distributed Tracing and How to Implement it with Open Source? Here, we'll look at some of the best distributed tracing tools. We'll see what each of them offers so that you can choose the right tool for your monitoring and observability requirements.

Mastering NodeJS Performance Monitoring - A Practical Guide using Open Source Tools

Node.js powers some of the fastest-growing web applications, but its single-threaded nature makes it vulnerable to memory leaks and CPU spikes. To keep your app running smoothly, especially in production, you need more than just web server logs — you need complete visibility across the entire stack.

Smarter alerts using P75 for more signal and less noise

We've rolled out a new feature in Raygun Alerting that gives you more control over how you track and respond to performance regressions. Starting today, you can now use the 75th percentile (P75) as a filter option for page performance data in Real User Monitoring, such as Core Web Vitals and page load time, right alongside the default 'Average'. This option is available under the "Page/XHR performance change" condition and supports all the Web Vitals metrics we track: Let's break down why this matters, when you should use P75, and how it gives you better, faster insights into how real users are experiencing your site or app.
