Exception Handling in Ruby

Software systems can be quite prone to error conditions. Systems that involve user interaction are more vulnerable to exceptions as they attract errors at multiple fronts. Errors can take many forms - syntactical errors, network errors, form input errors, invalid authentication errors etc. If not accounted for, these can affect user experience and can even manifest as security loopholes, enabling attackers to compromise the system.

Partnering with Render and Manifold

We’re thrilled that ScoutAPM is now available on Render via Manifold’s new Marketplace-as-a-Service offering. For those of you not familiar, Render is a new unified cloud platform that lets developers build and run all their websites, apps, static sites, background workers, and microservice APIs from one place at a lower cost than traditional cloud platforms.

Introducing AutoInstruments: zero-effort performance monitoring of custom Ruby code

Instrumenting the performance of custom code (the code you write, not the libraries you require) in web apps has been a thorn in my side for years. Yes, we have a custom instrumentation API, but raise your hand if you enjoy sprinkling your code with this? Anyone? Having a custom code instrumentation blackhole doesn't matter if your app spends almost all of its time in common libraries that Scout instruments by default (ex: ActiveRecord, Redis, View Rendering, and HTTP calls).

Birds of a Fiber: A look at Falcon, a modern asynchronous web server for Ruby

The GitHub Readme describes Falcon as, "... *a multi-process, multi-fiber rack-compatible HTTP server ... Each request is executed within a lightweight fiber and can block on up-stream requests without stalling the entire server process."* The gist: Falcon aims to increase throughput of web applications by using Ruby’s Fibers to be able to continue serving requests while other requests are waiting on IO (ActiveRecord queries, network requests, file read/write, etc).

Python Profilers

Python performance measurement tools help us to identify performance bottlenecks in our app. This allows us to focus on the business logic as opposed to writing custom code, setting it up with our app, and then figuring out whether the results are accurate enough. These tools are well tested by the open source community and used by many companies to measure the performance of their web apps.

Understanding page faults and memory swap-in/outs: when should you worry?

Imagine this: your library is trying to step up its game and compete in the Internet age. Rather than you browsing the shelfs, trying to remember how the Dewey Decimal works, you'll enter your book selections from your phone. A librarian will then bring your books to the front desk. You place your book order on a busy weekend morning. Rather than getting all of your books, the librarian just brings one back.

Monitor a Laravel app with Scout

Last month we talked about the PHP monitoring landscape in 2019 and announced that Scout APM would soon be available for monitoring your Laravel applications too (as well as your Ruby, Python and Elixir apps of course!). Now that our PHP monitoring agent is ready for beta testing, we thought it would be a good idea to show you folks how easy it is to get started with it and to highlight the main features to the Laravel community.

Honeybadger Integration with Scout

We are happy to announce that Scout now integrates with the popular error monitoring solution, Honeybadger. This integration brings a similar feature set to our existing Rollbar, Sentry and Bugsnag integrations, and it allows you to see your errors and exceptions alongside your performance metrics all on a single page. So let’s take this opportunity to take a closer look at Honeybadger and see how you can get it setup within Scout in just a few minutes!
