Tests are often treated as a safety net: something that catches bugs before they reach users. While that’s true, it’s only part of the story. A test suite is also a mirror. If you look closely, it tells you a lot about the structure, health, and long-term maintainability of your codebase. If you know how…
Read MoreUnexpected reboots, who doesn’t love them? A few weeks ago, we faced a problem that any platform engineer dreads: one of our nodes rebooted unexpectedly. The cause? The iDRAC watchdog forcefully terminated it. But what led iDRAC to decide it was time to shut down the node? A preliminary investigation concluded that there wasn’t any…
Read MoreOne of the most annoying aspects of using Sealed Secrets is their encryption design. They are tightly coupled to the namespace and name of the target Secret, meaning any changes to either require re-encrypting the Sealed Secret. This rigidity complicates workflows, especially when you need to duplicate or promote Secrets across environments. It breaks the…
Read MoreAs traffic to applications deployed on OpenShift grows, it’s essential to gain visibility into the flow of data entering your cluster. Monitoring this incoming traffic helps administrators maintain optimal performance, reduce security risks, and quickly resolve any emerging issues. Enabling Logging All traffic directed to an OpenShift Route is routed through a designated set of…
Read MoreFix for icinga2 satellites zone validation Fixed an issue with the icinga2 satellites zone validation that caused the neteye satellite config create to fail if one of the icinga2-zone is a sub-string of the others List of updated packages To solve the issue, the following packages have been updated
Read MoreWriting high-performance code is key when tackling complex problems. While it might be tempting to focus on optimizing the programming language itself, the best strategy is often to implement the right algorithm. Let’s take a look at three lesser-known Python libraries that can boost your code’s efficiency without diving into complicated implementations. 1. Deque: The…
Read MoreIf you’re monitoring an OpenShift or a Kubernetes cluster with Elastic Stack, you might’ve noticed that the Kubernetes integration uses the default Index Lifecycle Policy. It means that those logs and metrics have an unlimited retention. If the volume of logs is high – and for Kubernetes clusters it usually is – it won’t be…
Read MoreWhen monitoring Kubernetes clusters using Elastic Stack, the volume of logs can be overwhelming, often reaching gigabytes per minute. This is particularly true for OpenShift clusters, where significant traffic originates from system namespaces you might not be familiar with. Optimizing log collection becomes crucial for maintaining system efficiency and resource utilization. Success in this endeavor…
Read MoreLogs should be centralized, easily accessible, and independent from the monitored objects. Therefore, it’s advisable not to rely solely on the built-in monitoring system of OpenShift; instead, consider using an additional external monitoring solution. In this article, we’ll explore how to monitor an OpenShift cluster using Elastic Stack. Installing the Integration Since OpenShift is entirely…
Read MoreSecuring your codebase is a fundamental step in guaranteeing the integrity of your software: if the access to your git commits is compromised, so is your whole supply chain. That’s the reason why almost every git hosting service has implemented a strong authentication system to protect their users from unauthorized access. The question naturally arises…
Read MoreRPM Mirror We fixed some bugs related to the NetEye rpmmirror: Updated packages We updated the following packages: Post installation steps After installing the neteye-pulp3-mirror package you should re-run the setup of the rpmmirror ( neteye rpmmirror setup ) to make the bugfixes effective.
Read MoreRPM Mirror We fixed some bugs related to the NetEye rpmmirror: Module Audit Log We also fixed another bug in the audit log module that did not allow correct display in environments with many logs. Updated packages We updated the following packages: Post installation steps After installing the neteye-pulp3-mirror package you should re-run the setup…
Read MoreWhen deploying new features, releasing your code into a production environment might not be as easy as it seems. To ensure the minimal amount of service disruption, we might want to easily roll back to a previous configuration or to gradually migrate traffic to a new one. That’s where blue-green deployment comes to our aid….

Read MoreWe fixed a bug that was preventing the upgrade from 4.29 to 4.30 and removed some concurrency issues occurring in cluster environments. Furthermore we fix a a bug where the neteye_secure_install would overwrite dashboard UIDs in some edge-cases. For NetEye 4.29 we updated the following packages:
