Apache logs are a critical tool for monitoring your web server, but they can often feel overwhelming. For DevOps teams, understanding these logs is essential for diagnosing issues and maintaining system reliability. In this guide, we'll explore the setup and analysis of Apache logs, offering practical tips to help you make sense of them and use them effectively for troubleshooting and optimization.

In monitoring setups, working with a single metric rarely tells the complete story. The real power of Prometheus lies in its ability to query multiple metrics simultaneously, creating connections between different data points that reveal the true state of your systems. This guide will walk you through everything you need to know about crafting effective multi-metric queries in Prometheus – from basic concepts to advanced techniques that will help you monitor and troubleshoot your infrastructure.

Welcome to the latest HPE OpsRamp product update blog! Here, you'll find the latest news on exciting features, enhancements, and releases designed to elevate your experience with our product. Let’s dive into what’s new for the month of April. Transformed Usability Experience, Dashboard Improvements and New Visualizations.

In our previous article, we outlined what a Linux coredump is and how they work under the hood. One common constraint we see in embedded Linux, however, is a limited amount of storage space. Whether we’re trying to limit writes to disk, or need to reserve most of the disk space available to a device for other data, sometimes we just don’t have enough space to store coredumps.

Happy May the 4th be with you day! For all you lovers of Star Wars, technology, or space exploration, we've created this article to show examples of how the internet was used in space in your favorite Star Wars films, prequels, sequels, and TV shows. We will then return to Earth to see how the internet in space is currently used by astronauts on the International Space Station and what the future holds for the internet in space due to current advances in satellite internet. But before we jump in...

In this article, we will be continuing our series of deep dives into KIP-405. Previously, we covered: Now, we turn our attention to the internals of the read and delete paths. Just like we did for the write and metadata, here we will also be focusing on Aiven’s battle-tested Apache-licensed KIP-405 plugin. What makes the read path particularly interesting is how it delivers latency comparable to local disk or memory systems despite leveraging external object storage—let's dive in!

Designing user interfaces for Icinga Web is always a bit of a balancing act. Once we’ve worked through all the technical and conceptual details of a new feature, it can be tough to step back and see things from a fresh user’s point of view. We as developers know too much — and that makes it hard to guess how others will understand what we’ve built.

As enterprises continue their cloud and container journeys as part of modernization efforts, they are realizing “hybrid reality” is here to stay. For many, moving all services to clouds or containers is not a viable option. As a result, at least some services will be required to remain on premises. This presents unique challenges and ongoing complexity for monitoring and observability.

The cloud is the backbone of modern businesses, revolutionizing the trajectory of innovation, technology and business itself. While its promise of instant scalability and flexibility drives unprecedented growth, these same advantages can become a double-edged sword. The ease of spinning up new resources, automating deployments, and expanding services across regions—all of which make the cloud so powerful—can quickly lead to sprawling infrastructure and runaway costs if not carefully managed.

Jenkins is an open-source automation server widely used for continuous integration and continuous delivery (CI/CD), enabling developers to automate the building, testing, and deployment of software projects. Jenkins requires a good layer of visualization as it provides real-time visibility into pipeline performance, build statuses, test results, and deployment progress.
