Targeting hosts and services in Icinga 2 API requests

Today, we are going to take a look at the Icinga 2 API and the various ways targets can be specified for different actions, such as querying information or scheduling downtimes. This post focuses on the API request payloads themselves and assumes some familiarity with sending requests to the Icinga 2 API. Please refer to our documentation for the missing details if you want to try the requests yourself. In general, specifying the objects to which an action applies works the same way for all actions.

Shift Left on Performance Testing - Without Killing Developer Velocity

Traditional performance testing often comes late in the delivery cycle, typically just before release. By then, performance issues are usually quite expensive to fix, can delay deployments, and frustrate development velocity. A Shift Left testing approach addresses this by integrating performance testing early in the development cycle so issues surface while they’re still easy and cheap to fix.

Don't Just Monitor SLAs - Validate Them Automatically

Service level agreements (SLAs) are the contractual backbone between customers and technology vendors, outlining expected service availability, performance metrics, and remedies like service credits when service providers fail to meet agreed-upon service levels. This service agreement assures both the technical quality as well as the service quality of the services provided, and underpins the value perspective of the client.

Your APIs Are Green. Your Background Jobs Are Dying.

Launch Week Day 2: Introducing Discover Jobs Your dashboard looks perfect. APIs responding in 80ms. Error rates at 0.02%. Kubernetes pods healthy. Everything's green. Then Slack explodes: "Why didn't my invoice generate?" "Where's my password reset email?" "The data export I requested yesterday is still processing?" You check your job queue. Sidekiq dashboard shows 47,000 jobs processed today. Redis looks fine. Workers are running. But somehow, your business logic is silently falling apart.

Best of both worlds: relaxAI API brings sovereignty and affordability to OpenAI

The UK’s Competition and Markets Authority (CMA) recently published its final verdict on the state of the cloud industry. While the tone may have softened since its initial findings, the conclusion was still damning: hyperscalers like AWS and Microsoft continue to unfairly dominate the cloud market through opaque, inflated pricing and technical lock-in strategies.

Transforming Snapshots with Templates

Ever wished you could save and reuse your API traffic transformations? With Speedscale's new snapshot templates feature, you can! In this demo, we'll walk you through how to: Find and filter API traffic to create a snapshot. Transform sensitive data, like authentication tokens, with templates. Apply those saved templates to new snapshots instantly, saving you time and ensuring consistency. Whether you're looking to automate your testing or handle sensitive data more efficiently, our new templates feature makes it easier than ever to manage your API snapshots.

Zero Trust Architecture Needs Zero Guesswork

The Zero Trust model has fundamentally shifted how organizations secure their applications and infrastructure. Instead of assuming anything inside your network is safe, the Zero Trust security model requires continuous verification of every identity, every device, and every access request across the entire trust model, forcing users and devices to prove that they can access what they are trying to access.

Honeycomb Launches Integration With the Anthropic Usage and Cost API

If your organization is anything like ours, then you’ve probably embraced using large language models like Claude. Just last week, we gave all Honeycomb employees access to Claude. Now, developers can generate AI-assisted code, product managers can perform analysis on customer usage trends, marketers can test messaging, sales can do customer discovery and we are shipping AI-powered features to improve user experience.

Run Checkly Monitors Against Multiple Environments

Learn how to run Playwright tests across different environments without rewriting them. This tutorial covers managing environment variables in Checkly for API and browser checks, handling global and group-specific settings, and integrating with CI/CD processes. Discover the best practices for setting up environment variables, duplicating test groups, and customizing alerts to ensure your checks are environment-specific.

REST easy with REST Packs

The countdown to CriblCon 25 is on and we’re giving you an exclusive first look at the expert insights, innovative solutions, and success stories you’ll see on the big stage. REST collector configuration can be painful, requiring navigating to multiple screens and importing multiple configuration files, but it’s about to get a lot easier. Join Cribl experts to preview how easily you can install and build new packs with new enhancements.

Traffic Replay: Production Without Production Risk

The software and product life cycle is fraught with pitfalls and tradeoffs. While testing applications under production-like load is critical to ensuring the reliability, performance, and security of your data storage and software services, you need to do this testing without actually affecting the production data and systems. In essence, you have to pull off the impossible - be as close to production as you can without actually being production.

Stop Guessing with OAuth: Understanding CI/CD

OAuth 2.0 is the leading open authorization framework that enables secure delegated access to protected resources. From traditional web apps and browser-based apps to native apps and desktop applications, OAuth allows client apps to grant access on a user’s behalf without exposing login credentials, enabling powerful third-party applications, custom data flows, and powerful user experiences. However, while OAuth is secure, it’s not always fast.

Your APIs are up, but did the payment go through?

If your challenger bank is built on composable core platforms like Mambu or Temenos, this one’s for you. Composable platforms enable API-first integration with modular services, letting you launch, adapt, and grow products quickly. That makes API health a top priority — and it shows in our State of API Reliability Report 2025 (we’ve pulled out the key fintech findings for APAC below).

Data Sovereignty Is Everyone's Problem

Data sovereignty isn’t just a niche consideration anymore – it’s a central requirement in everything from cloud computing and analytics to software development. The environment of 2025 is significantly different from that of 2015, and even more so from 2005. What was once a patchwork of guidance documents, data privacy laws, and local regulations has given way to massive EU-wide regulations, multinational frameworks, and a greater focus by users on digital identity.

Speeding up AI Coding Assistants using Deterministic Feedback

AI coding assistants are transforming the way developers approach software development by automating routine tasks and enhancing code quality. These tools leverage artificial intelligence and machine learning to provide real-time code suggestions, auto-complete functions, and even debug existing code, making the development process faster and more accurate. Modern AI coding assistants integrate seamlessly with a wide range of programming languages and frameworks, including Java, Python, and C++.

Vibe coding with the incident.io API

Many, many years ago, I was a computer science major at the University of Illinois, hoping someday I’d be able to write code for a living. I started my career in QA hoping to learn the ins and outs of software development. But it turns out I wasn’t very good at coding. I was just good enough to get a role as a sales engineer, where all I had to do was write code that could hold together for 30 minutes in a demo.

AI Agent Is Hitting Your APIs - Are You Ready?

It’s no longer theoretical – artificial intelligence has left research labs and entered production systems, generating a new breed of consumers – autonomous and intelligent agents. These autonomous AI agents are increasingly interacting with real-world APIs (application programming interfaces), which are sets of protocols and tools for building and integrating software applications.
