When it comes to data, let’s start with the obvious. Averages suck. As developers, we all know that percentiles are much more useful. Metrics like P90, P95, P99 give us a much better indication of how our software is performing. The challenge, historically, is how to track the underlying data and calculate the percentiles. Today I will show you how …
A PHP application might produce many different levels of earning and errors during its execution. Being able to see these errors is essential for developers trying to troubleshoot a misbehaving application. However, developers often have trouble when trying to display errors from their PHP applications. Instead, their apps just fail silently. If you are having problems with your PHP web …
Why is monitoring microservices so important? It’s because we work in a time where systems are complex, distributed across multiple microservices. For example, even a simple e-commerce app may have Ordering, Product Catalog, and Shipping services. Our tooling and practices sometimes struggle to keep up with such complexity. It reminds me of music and video games. In the early days …
DevOps teams have more on their plate than ever. As infrastructure needs grow, so does the time required to ensure that everything’s running smoothly. This makes automation crucial – especially in the server and network monitoring world. Server monitoring tools can save teams time by automating server management and providing real-time performance updates. As budgets reset for the New Year, …
Would you like to detect problems in your Amazon Redshift environments? Does your team need a high-level overview of what monitoring options they can choose from when they deploy Redshift nodes and clusters? First, we’ll start with one of the most important components of any monitoring strategy: performance and availability monitoring. Then, we’ll continue with monitoring Redshift configuration changes and …
Writing software is hard. Balancing the demands of shipping with assuring quality presents challenges. Also, you must have an eye on keeping code readable and maintainable. It’s not easy. Beyond mere development, maintaining a running application is still harder. Serving users requires responding to problems in a timely fashion. In order to respond to problems, you need to know they …
Fans of Star Trek: The Original Series know that The Enterprise was not capable of going past Warp Factor 8 for long periods of time. That would be all the power Scotty could give the starship before it started breaking up. I know that you love Star Trek (who doesn’t?) but you might be wondering: what does this piece of …
As companies evolve from a monolithic architecture to microservice architecture, some common challenges often surface that companies must address during the journey. In this post, we’ll discuss one of these challenges: observability and how to do it in AWS Fargate. A Little History Before Talking AWS Fargate Monitoring Twenty years ago, applications were different from what they are today. They …
Today’s post is a detailed guide on how to send custom metrics to AWS CloudWatch monitoring using AWS Lambda. Starting from scratch, we’re going to finish up this post by leaving a serverless project running on Amazon Web Services (AWS). And do you want to hear the best part? Getting started will cost you less than you might spend on a …
People who are new to hosting web apps on IIS (Internet Information Services) sometimes struggle with the concept of application pools. What is an IIS application pool? What purpose does it serve? In this post, we’ll answer these questions—and more. We’ll begin by offering a brief introduction to IIS itself. If you’re already well acquainted with this piece of software, …
Imagine a man, a metaphorical man, slumped over, sitting silently across from you. Do you see him? Hastily smashing his fingers against the keyboard with a feverish sweat running down his neck. He, like many, only opens his APM solution after those universally feared “oh shit!” moments. Like a firefighter with a magnifying glass, he dives into his logs looking …
New Relic is one of the industry leaders for SaaS-based application performance management. However, many are starting to look for new relic alternatives and competitors. Probably about half of those alternatives are available as SaaS APM. New Relic Pricing Forcing You to Look for Alternatives? We talk to companies every day that are currently using New Relic but are looking …
As PHP applications are getting more complex, it’s becoming harder to deliver high-quality applications. It’s more important than ever to perfect your process for PHP performance monitoring. Tools like Application Performance Monitoring (APM) are essential for the development process. To get good performance data, developers need to deal with the rising trends of containerization, microservices, heterogeneous cloud services, and big data. To …
If you use PHP or you find yourself “adopting” a PHP app (like I did a few years ago), you must know how to debug PHP. In this detailed guide to PHP debugging, you’ll see some debugging techniques that apply to almost any programming language. But don’t worry. I’ll get into the specifics that apply to PHP, from the basics all …
Performance tuning MySQL depends on a number of factors. For one thing, MySQL runs on various operating systems. For another, there are a variety of storage engines and file formats—each with their own nuances. In this tutorial, you’ll learn how to improve MYSQL performance. But first, you need to narrow the problem down to MySQL. Let’s say Retrace is reporting …
Setting up the database correctly is just the first step in PostgreSQL performance tuning. With every table you add and every query you run, your databases will require maintenance and updates to ensure ideal PostgreSQL optimization. PostgreSQL optimization is pretty straight-forward, however, there are some things that it needs to know from you, the database admin, in order to run …
Providing your users with the best possible software is always the number one priority. But doing so in the fast-paced, ever-changing technology landscape we live in isn’t a simple task. As soon as an update is deployed, it seems like the need for the next is already here. This has been a constant battle of development teams for decades. The …
1. Introduction In this article, we’ll discuss Java performance testing approaches that can be helpful for improving the performance of a Java application. We’ll start with how to define measurable performance goals and then look at different tools to measure, monitor application performance and identify bottlenecks. We’ll also look at some of the common Java code level optimizations as well …
Application Performance Monitoring, or Application Performance Management (APM), has become the de facto standard for providing better customer experiences and applications. APM allows you to observe the performance of your application including such valuable metrics as load time, errors, logs and transactions. Mobile and web applications have similarities, but there are striking differences between the two. Mobile applications depend on …
We are living in a golden age of programming. The language and tooling have never been better. Not a day goes by that I’m not impressed by some new programming language feature (how cool are nullable reference types in C#?); or a new technology (Live Share and Teletype are going to change the lives of remote developers); or some adaptation …
