Do you have a Prometheus histogram and have you asked yourself how to visualize that histogram in Grafana? You’re not alone. Here, we will show you how it’s done. This post assumes you already have a basic understanding of Prometheus and Grafana and it will look at Prometheus histograms from the perspective of Grafana 7.0.
Tag mutability can introduce multiple functional and security issues. In container land, tags are a volatile reference to a concrete image version in a specific point in time. Tags can change unexpectedly, and at any moment. In this article, we’ll learn how we can prevent them.
One of the most important aspects of any Chaos Engineering program is knowing that every experiment is being run safely. And one of the simplest ways to ensure safe experiments is by having safeguards that prevent running chaos experiments on a system that is unhealthy or has an incident in progress. Today, Gremlin is excited to announce Status Checks, which run before you kick off a Chaos Engineering Scenario in order to verify your system is in a steady state.
Building a healthy productive engineering culture is hard and just deploying frequently with continuous deployment is not enough. I'm going to show you how you can use a carrot, not a stick, approach to take continuous deployment to the next level by celebrating team values with Sleuth.
This Tip of the Day is the first in a three-part series on Domain Name System (DNS) monitoring. The Domain Name System is often described as “the phonebook of the Internet.” While humans access the Internet via domain names such as npr.org or bbc.com, web browsers interact via Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so that browsers know which Internet resources to load.
Responsibilities are shifting between software developers and operators due to the increasing adoption of agile development practices, DevOps, and GitOps. This makes it challenging for developers and operators to effectively collaborate in order to increase developer agility and productivity. D2iQ’s Dispatch is built on a cloud native foundation, leveraging Tekton and Argo CD to simplify running CI/CD on Kubernetes with a simplified user experience.
The most successful software development movement of my lifetime is probably test-driven development or TDD. With TDD, requirements are turned into very specific test cases, then the code is improved so the tests pass. You know it, you probably use it; and this practice has helped our entire industry level up at code quality. But it’s time to take a step beyond TDD in order to write better software that actually runs well in production. That step is observability driven development.
Kubernetes has emerged the de facto container orchestration technology, and an integral technology in the cloud native movement. Cloud native brings speed, elasticity, and agility to software development, but also increases the complexity — with hundreds of microservices on thousands (or millions) of containers, running in ephemeral and disposable pods. Monitoring such a complex, distributed, transient system is challenging, and at the same time very critical.
