Enter the Metrics: Measure App Performance In Real-Time, On-Demand

When it comes to understanding what’s happening in your code – and your service health, specifically – business and code-level metrics are key. While most developers are experts in their own code, that doesn’t mean that they’re also experts on the metrics, statistics, or distributed tracing from the code they’re working with. The code-level metrics they need are tough to set up and it’s something that no one else can do for them.


Top 10 Debugging Tools in 2023: The Only List You need!

As we move past the stage where automation is no longer the concern, intelligence is at the front seat, being the driving force of technology in almost every space. With lines of codes that are being thought upon, strategized upon, and then implemented, viruses, and bugs, are no Bueno. Since the world is moving more towards online communities than physical ones, these bugs and viruses create havoc and disorient business functioning.


90-Second Hack To Install A Node.JS Agent With No Code Changes

Installing Rookout on your Node.JS application is usually a breeze. Run `npm install`, add a line of code, and you are done. Yet, in some rare cases, we encounter more frustrating use cases. For example: When those tough situations arise, our customers often refer to this blog post we wrote years ago about deploying a Java Agent. So, if you are looking for an easy and portable way to deploy Node agents without changing your code, you’ll want to read this article.

Should you wake up in the middle of the night because production is down - Liran Haimovitch

In many engineering positions today, especially in DevOps engineering (yeah, yeah, I know it’s not an actual position…), you get asked to take an on-call rotation, spending your precious nights and weekends firefighting when production is down. In this talk, we will dive into the whys and why nots of doing just that.

Debugging and Tracing in Erlang

In part one of this series, the debugging tools we used — Elixir's IO.inspect/2, IEx.pry, and dbg/2 — required us to insert changes into code directly. Outside the development environment, you probably won't (and shouldn't) have access to your code. Erlang has a few tools to debug code at runtime: :debugger, :dbg.tracer, and :observer. First, let's look at the:debugger, a graphical debugging tool. Let's get going!


Testing Vs Debugging: The Differences You Need to Know!

We know about Testing and Debugging. But what is the difference between these two processes? Why are these two processes essential for software development? In this article, we will find answers to all these questions. You will learn about the features, the tools used in each process, and the types. Did you know Testing and debugging are two essential processes in software development?


How To Use Mock Data Without Changing Internal Logic

In every job and every company, that day always comes where you find that you…actually need to do some work. And by that, I mean finding new innovative solutions to tasks and projects instead of going with the tried-and-true methods. Recently, my team, of full stack developers were tasked with building a webview app to support our live debugging IDE plugin. This would allow us to align the user experience with our pre-existing web app.


StackDriver Debugger Is Out - What's Next For You?

If you have been a long-time user of the Google Cloud Platform, you’re likely familiar with the StackDriver suite of Observability and Operations tools. The most unique part of that suite was Google’s StackDriver Debugger, which was designed to debug live code in cloud and production environments with a click of a button. Unfortunately, StackDriver has been renamed as Google’s Operations suite, and the Debugger has been deprecated.
