Hello again! It’s a historic week here at AppSignal! This week we released the first version of our new and improved JavaScript error monitoring. Now you can have your front end code, Ruby or Elixir back end code, your hosts, performance, everything monitored in one interface. To celebrate the launch, in a two-part series of posts, we’ll be taking a look at the history of Errors in JavaScript, including how to handle them in your code today.

Chaos engineering (CE) is the discipline of experimenting on a system in order to build confidence in the system’s capability to withstand turbulent conditions in production. This approach is becoming commonplace in software development and operations (DevOps) practices. But how would its application extend to ITOps? CE for ITOps offers a similar framework for stress-testing a technology platform to understand its weak points and performance pitfalls under heavy pressure.

Experience NYC hosted several quality speakers but one in particular stood out to me for his unique message: Andrew Hewitt, a leading IT Analyst from Forrester. Probably the last thing you would expect to hear at an IT solutions conference is a captivating talk grounded in human psychology. Feelings? Perceptions? Beliefs? These topics don’t seem to fit nicely into bits and bytes. They’re perceived as foreign, un-engineer speak.

When it comes to monitoring web application performance, not only is it necessary emulate user actions, but also network conditions of end-user devices. Network throttling allows you to control connection speeds to better match the experience of real users, allowing you to see web application behavior in specific network conditions. Network connections can vary for many reasons. User location, device type, and browser used are just a few factors that can affect a user’s experience.

For the month of October, we’ve added three new checkpoint locations for a total of 212, and we’ve updated the IP addresses of three more checkpoints. We keep adding new checkpoints because you need to monitor your websites and web services from as close to your users’ locations as you can get. A few randomly placed monitoring locations or just monitoring from the cloud (who’s users are in the cloud anyway?) doesn’t cut it.

At Grafana Labs, we are working to make it easier to visualize data that comes from many different sources and in many different ways. We know that our customers are usually using more than one system to track what’s going on within an infrastructure. If you are a system administrator, or even a curious developer, there is a very high probability that you are monitoring and quite regularly reviewing your logs to find valuable and important information in them.

A critical vulnerability in sudo has been disclosed, that when exploited, enables users to bypass security restrictions and execute commands as the root user. This security flaw has to be swiftly remediated as sudo is one of the most integral and commonly used functionalities in Linux operating systems.
