Setting up triggers within AppSignal is a powerful way to discover that the bits started hitting the fan. You can use triggers to get an alert if an error rate is higher than 1%, your server runs out of memory, or even if your hourly login drops to zero. Our latest update makes the creation of triggers much easier.
Garbage collection (GC) is a very important process for all programming languages, whether it’s done manually (in low-level languages like C), or automatically. The curious thing is that most of us barely stop to think about how JavaScript — which is a programming language, and hence, needs to GC — does the trick. Like the majority of high-level languages, JavaScript allocates its objects and values to memory and releases them when they’re no longer needed. But, how?
Whether you write code to save the bees, build the latest CMS, or teach others to become a developer: we’ve got your back. We’ve always offered AppSignal for free to maintainers and do-gooders who asked, such as Elixir School, Code::Stats and the MEANS Database. Starting today, we want to spread the word to all open-source maintainers and volunteer organizations that AppSignal is 100% free for them.
Logs are an important part of your application and logging shouldn’t be one of the last things you think of. You should configure your log system, formatter, and style as soon as you start the development of your app. Also, do your best to document the process and share how it works with the rest of your team. In this article, we’re going to demonstrate how logs work in Elixir. We’ll jump into Elixir’s Logger module, which brings a lot of power to logging features.
Do you know how many errors your Node.js application had last week? How many users were affected? Which servers were high on CPU/Memory/Disk? If you do know, how many different tools did you have to install, and how many hours you’ve spent configuring all those tools? AppSignal is here to change the way you monitor your apps and simplify your life as a developer. Today, we officially launch the 1.0 version of @appsignal/node.js.
