Gatling is a load testing tool for measuring the performance of web applications. As such, it supports the following protocols: HTTP, WebSockets, Server-sent events. Other protocols are also supported either by Gatling itself (like JMS) or by community plugins. Gatling load testing scenarios are defined in code, more specifically using a specific DSL. This guide focuses on the basics of writing a simulation to test an HTTP application: OctoPerf’s sample PetStore.

It has been almost three years since we first published our first comparison & benchmark articles that have become very popular, and we thought an update seemed overdue as some tools have changed a lot in the past couple of years. For this update, we decided to put everything into one huge article - making it more of a guide for those trying to choose a tool.

Today, countless engineering teams have leveraged API monitoring to track infrastructure health and report when services are down or unhealthy. There are a variety of API metrics that can be tracked that are aligned with engineering goals such as uptime, average latency, requests per minute, and errors per minute. However, these metrics are not aligned with the business goals of product owners and growth teams.

In today’s post, we’ll learn how to build a Rails app that can support multiple subdomains. Let’s assume that we have a gaming website funkygames.co and we want to support multiple subdomains such as app.funkygames.co, api.funkygames.co, and dev.funkygames.co with a single Rails application. We want to ensure that proper authentication is performed for all subdomains and that there are no duplicate routes.

Nearly eight years ago, Cory and I started on a journey to help developers build software quickly and painlessly. As software developers ourselves, we had felt the pain of being afraid to ship and spending late nights tracking down bugs. In 2013, we launched Rollbar into the world so that developers could build software faster, shipping often without fear. These days, lots of people talk about continuous delivery, and nearly all of them focus on automating releases.

PHP isn't typically thought of as a solution when creating worker or background processes, jobs that typically can last for an extended period. These can be tasks such as image processing, file repair, and mass email batch jobs. Typically, PHP is linked with HTTP requests, requests which are short in duration and stateless in nature. However, just because of this enduring association, it doesn't mean that PHP can't be used for background processes. On the contrary.

Have you ever looked at your website logs and realized they don’t make sense to you? Maybe your log levels have been abused, and now every log categorizes as “Error.” Or your logs fail to give clear information on what went wrong, or they reveal sensitive information that hackers may harvest. Fixing these problems is possible! Let’s explore how you can write meaningful log messages and use log levels correctly.

Welcome to Stackify’s guide to C# exception handling. Why is this topic so important? In modern languages like C#, “problems” are typically modeled using exceptions. Jeff Atwood (of StackOverflow fame) once called exceptions “the bread and butter of modern programming languages.” That should give you an idea of how important this construct is.

Microservices are small, independently-running applications that perform a single function for a larger application or IT infrastructure. By loosely connecting a number of them together, developers create a pluggable architecture that facilitates the process of updating, upgrading, and scaling the application in response to changing requirements.

One of my favorite Talend customer success stories is the International Consortium of Investigative Journalists (ICIJ). I love this story not only because they transformed investigation journalism with data, won the Pulitzer prize for the Panama papers, and helped the public to recover billions of dollars lost to illegal tax evasion.
