Our third party metrics and dashboard have had an exciting revamp. With new metrics like blocking CPU, you can now see exactly who is really to blame for a crappy user experience. We've also given you the ability to monitor individual third parties over time and create performance budgets for them. It's not you, it's me. Or is it really you, and not me?

Today's websites are packed with heavy media assets like images and videos. Images make up around 50% of an average website's traffic. Many of them, however, are never shown to a user because they're placed way below the fold. What’s this thing about images being lazy, you ask? Lazy-loading is something that’s been covered quite a bit here on CSS-Tricks, including a thorough guide with documentation for different approaches using JavaScript.

MySQL Server generates several logs that can help you monitor the activities of the server. However, once these logs are enabled, they can grow in size and start taking up too much disk space. This is why it’s important to have an automated way of archiving and preserving MySQL log files for a certain duration, as well as deleting the old ones. In this blog post, we describe some best practices for setting up and managing MySQL error logs, general logs and slow query logs for your MySQL deployme

Especially in dynamic microservices architectures, distributed tracing is an essential component of efficient monitoring, application optimization, debugging, and troubleshooting. Basically, it’s all about seeing how different services are connected and how your requests flow through those different services.

We have all been in situations while using software or a web applications where everything is running too slowly. You click a button and nothing is happening except a loader animation spinning for a seemingly infinite time. The worst case is when end users face this kind of issue. This is bad news for the developer or the owner of the application. These are because of performance issues, and the only way this can be eliminated is through performance testing.

When building an application that allows users to have accounts, you have to ensure that access to these accounts is secure. When building a user account system, an important factor to keep in mind is how passwords are stored. Storing passwords as plain text is a complete rookie move that leaves your users vulnerable to all sorts of data breaches. The best way to protect passwords is to employ hashing and salting and in this tutorial, we’ll show you exactly how to do this.
