Introduction For on-premise Elasticsearch installations, performing a rolling restart across a cluster can be a time-consuming task, especially when dealing with large clusters. Rolling restarts are typically required when changing node configurations or upgrading the cluster to a new version. Elastic provides an official procedure to ensure service continuity during this process. However, after analyzing…
Read MoreToday we continue our journey into monitoring automation in NetEye. In my previous post we discussed the possibility of automating Business Processes. As you may remember, for those of us working on NetEye Cloud monitoring dozens of clients, it’s important to be able to standardize and automate the creation of BPs to have a consistent…
Read MoreAt first glance, rebuilding an RPM may sound like a purely mechanical task: take a patch, rebuild the package, ship it. In reality, that small fix goes through a much longer journey that touches reliability, security, trust, and long-term maintainability. In this article, we’ll walk through what really happens when a tiny upstream patch needs…
Read MoreDependencies (frameworks, modules, plugins, etc.) are the lifeblood of modern software libraries. But managing them manually is a burden. By automating dependency updates (in a controlled, smart way), you can stay ahead of security issues, reduce technical debt, and make upgrades less painful. Below I’ll walk you through why automatic updates matter, what to watch…
Read MoreAs enterprises move toward containerization and microservices, traditional job schedulers are often left behind. However, many organizations still rely on tried-and-true tools like SOS Berlin’s JobScheduler (now known as JADE under the JOC Cockpit umbrella). The good news? With a bit of engineering effort, you can bring JobScheduler into the world of containers. In this…
Read MoreHi! Today I want to talk to you about a nice tool that I stumbled upon in recent weeks: n8n. In these days automation has become a key driver for efficiency and innovation. From streamlining repetitive tasks to connecting disparate systems, businesses and developers are turning to automation platforms to save time and reduce human…
Read MoreAfter 17 years in software development, mostly crafting UIs (do you know Google Web Tookit? Or Angular, since version 1? And now Vue.js? I do), occasionally diving into mobile apps, and even wearing the sysadmin hat, I thought I’d seen my fair share of tech. But recently, I stepped into a completely new arena: Pipeline…
Read MoreGitHub Actions offer a powerful and flexible infrastructure for CI/CD, deployments and monitoring. But every external dependency we include opens a potential door for supply-chain attacks. One simple, effective, and low-cost way to seal that door is pinning your Actions to specific commit SHAs. In this article, we’ll explore the risks, walk through how to…
Read MoreIn NetEye, we use Ansible to automate many different tasks in an idempotent way, ranging from the first installation of the system to updates and upgrades. Ansible already comes with many built-in useful modules to manage files, perform HTTPS requests and much more. Furthermore, various Ansible Collections have been developed by the community to address…

In many organizations, customers request physical or digital assets via the Jira Service Management portal. Tracking the status of these deliveries and keeping the requestor informed is critical for transparency and customer satisfaction. This blog post outlines a robust solution using Jira Automation to manage and visualize the delivery process directly in the customer portal…
Read MoreWhen working with Atlassian Jira Automation and Assets, two key methods allow you to interact with Asset objects dynamically: Lookup Objects and Branch on AQL. While both serve similar purposes, they have distinct execution behaviors, performance considerations, and important limits you need to be aware of when designing automation workflows. Let’s break it down to…
Read MoreUse Case During NetEye Cloud updates we typically have to handle 25+ nodes, updating both OS and Firmware and subsequently rebooting all servers, all without causing downtime. We can of course reboot one node a time, but this would be really time-consuming. The main constraints on reboot are PCS nodes and Elastic layers. In particular…
Read More⚠️ Warning: This article is intended for educational and ethical purposes only ⚠️ Red teamers don’t often engage in DDoS campaigns or stress testing against client systems, mainly for two reasons: However, there are cases where clients explicitly request such activities. When that happens, the red team must be thoroughly prepared; both legally, to clearly…
Read MoreIn a previous blog post by one of my colleagues, we shared how we developed a powerful semantic search engine for our NetEye User Guide. This solution uses Elasticsearch in combination with machine learning models like ELSER to index and query our documentation. While the proof of concept (POC) worked great, there was a challenge…
Read MoreWhen adopting an open-source software project that you don’t own, you may find it necessary to modify it partially to meet your specific requirements. However, as you implement those changes, it’s important to recognize that the upstream project will eventually update itself, leading to potential conflicts in the files that both you and the upstream…
