How to Migrate an Icinga 2 Master in a High Availability Setup

Moving an Icinga 2 master to a new machine requires careful preparation, especially in a master-to-master high availability setup. In production environments, such migrations are often part of broader infrastructure changes, platform standardization, or long-term monitoring strategy decisions. This guide walks you through the process step by step, ensuring a smooth migration without service interruption while keeping your monitoring platform stable and consistent across the environment.

Turning Data Into Decisions with the xMatters Incident AI Agent

When an incident hits, the gap between awareness and action can make all the difference. Responders know the pain: endless tool-switching, chasing updates, and fragmented data. It’s not a lack of capability that slows response; it’s the lack of context and connection. That’s why we built the xMatters Incident AI Agent, a purpose-built, conversational assistant that brings intelligence and automation directly into the heart of incident response.

Follow-the-sun and other on-call models

Most teams run on-call using rotation-based schedules where responsibility shifts every few days or weeks. But some situations call for different models that change who responds based on time zones, expertise, or the type of incident that triggers. This guide walks you through six on-call models that work outside the standard rotation patterns.

5 Offbeat on-call rotations that work

Most teams choose standard on-call patterns like weekly or daily rotations. But sometimes a less conventional rotation can solve a specific problem or just fit better with how your team works. This guide walks you through five offbeat on-call rotations. For each, we look at why it might work for you and the challenges involved. This helps you see the full picture before you decide to try them out. Let’s dive in!

Monitor Fortinet FortiManager performance in Datadog

As enterprises scale, teams often find it harder to identify user-reported issues. Software-defined wide area networks (SD-WANs) can make it easier to add branch offices, but they can also make it more challenging to distinguish connectivity degradation from changes in application behavior. FortiManager provides a centralized control plane for Fortinet Secure SD-WAN and reduces operational complexity.

Why Upsun is the multi-cloud PaaS technical leaders are choosing in 2026

In a recent technical evaluation by Journal du Net (JDN), Upsun (formerly Platform.sh) was recognized for its ability to "pull ahead" (tire son épingle du jeu) in a fiercely competitive market dominated by cloud giants and specialized pure players. While hyperscalers offer raw power, Upsun’s strategic fusion of enterprise reliability and AI-ready agility has redefined expectations for modern PaaS.

Migration blueprint for moving your application without rewriting

The decision to migrate a production application is rarely about the destination. It is about the friction of the journey. For most engineering leaders, the word "migration" is a synonym for "refactor." The industry has conditioned us to assume that moving to a modern cloud platform requires throwing away years of stable configuration, learning a new proprietary DSL, and rewriting core application logic to fit a specific container or serverless model.

Incident Alerting: What We Believe It Should Do

Incident alerting is a critical part of modern operations, yet it’s often misunderstood or reduced to “sending notifications.” In reality, it is about ensuring that the right people are informed at the right time – and that incidents move from detection to action without confusion or delay. This page explains why fast, reliable alerting matters, where it fits between monitoring and incident response, and what best practices look like.
