One of the joys of using the Ruby language is the many different ways that you can solve the same problem, it’s a very expressive language with a rich set of libraries. But how do we know which is the best, most efficient, use of the language? When we are talking about algorithms which are critical to the performance of your application, understanding the most efficient approach to take is essential. Perhaps you’ve been using Scout to hunt down issues, and now that you have found an issue, you want to optimize it. Ruby’s Benchmark module provides a very handy way for you to compare and contrast possible optimizations, and when used in conjunction with a good APM solution it will ensure that you have all bases covered. Let’s take a look at how you can get started with it today!
Some members of the Tokyo Scout team travelled to Taipei last week to take part in RubyConf Taiwan. It was the first time that Scout has sponsored this event, so we were very excited to be invited to take part! During the conference we had the opportunity to speak with many interesting developers from all over Taiwan and Asia. It was a fantastic opportunity to show Scout in a new environment and to make connections with Ruby developers from all across Asia.
There is no doubt that looking at response times and memory usage is essential to understanding the general health and performance of your application. But as I am sure you are aware, there is more than one way to monitor an application. Approaching monitoring from a different angle can be a powerful way of gaining new insights. If all you did was watch for high response times or areas of memory bloat, then you might overlook something far more simple: the user’s general level of satisfaction. So how can we monitor this rather broad concept of user satisfaction? Well, we can monitor this with a rather useful metric known as the Apdex score...
With the official release of Rails 6 just around the corner, we round up all the major new features coming your way. It is an exciting release due to some big features coming upstream from the Basecamp and GitHub projects. Amongst the many minor updates, useful tweaks and bug fixes, Rails 6 will ship with two completely new frameworks: ActionText and ActionMailbox, and two big scalable-by-default features: parallel testing and multiple database support. So set your Gemfile to get Rails 6.0.0.rc1 and let’s get started!
Software development has changed rapidly over the last ten years. Many companies have moved away from the traditional waterfall development model to an agile methodology, and this has meant embracing continuous integration and continuous delivery practices. But how about taking it one step further with continuous deployment? Are you deploying to production automatically, without any human intervention? Some of the major products we rely on everyday are. We take a look at some of the best continuous deployment tools and put them head-to-head.
There is no denying the popularity of PHP. It has been a constant force in the web development world since its release way back in 1995. And now in 2019, thanks to Laravel, it is still going as strong as ever! Here at Scout, recently we have been working hard on providing a PHP performance monitoring agent to sit alongside our existing ruby, python and elixir agents. Prior to us releasing this PHP agent, let’s take a look at the PHP ecosystem to see how Scout can complement the existing monitoring landscape.
If you are hosting your application with Heroku, and find yourself faced with an unexplained error in your live system. What would you do next? Perhaps you don’t have a dedicated DevOps team, so where would you start your investigation? With Scout APM of course! We are going to show you how you can use Scout to find out exactly where the problem lies within your application code. We are going to walk through two of the most common Heroku error codes and show you how to diagnose the problem with Scout quickly and efficiently.
If you’re a Rails developer, then you’ve probably used Rails Logger on at least one occasion or another. Or maybe you have used it without even realizing, like when you run ‘rails server’ and it prints information to the terminal window, for example. Rails Logger provides us with a powerful way of debugging our applications and gives us an insight into understanding errors when they occur. But are you using all of the Rails Logger features? There’s a good chance you are not! So let’s take a more in-depth look at the logging system in Rails, look at some of its more unknown features, and establish some best practices for our log creation in the future.
How are you deploying your applications in 2019? Are you using containers yet? According to recent research over 80% of you are . If you are within this group, were you initially sold on the idea of containers but found that in reality, the complexity involved with this approach makes it a difficult trade-off to justify? The community is aware of this and has come up with a remedy to ease the pain, and it’s called container orchestration. So whether you are using containers or not, let’s take a closer look at container orchestration and find out what you need, what its used for and who should be using it.
How can we take our existing Ruby on Rails applications and run them inside a Docker Container? In a recent post, we talked about Docker containers, and what you should know about them. Hopefully we cleared up any confusion you might have had about the Docker ecosystem. Perhaps with all that talk, it got you thinking about trying it out on one of your own applications? Well in this post we’d like to show you how easy it is to take your existing Ruby on Rails applications and run them inside a container. So, let’s assume you have an existing Rails project with a PostgreSQL database, and let’s walk you through the steps it would take to run this in a container instead. It’s a lot easier than you probably think!
These days Docker is everywhere! Since this popular, open-source container tool first launched in 2013 it has gone on to revolutionize how we think about deploying our applications. But if you missed the boat with containerization and are left feeling confused about what exactly Docker is and how it can benefit you, then we’ve put together this post to help clear up any confusion you might have. What are Docker Containers? We take a look at the 8 things that you should know about Docker containers. We'll cover everything from Dockerfiles to Docker Compose to Docker Hub.
