Observability. Agentic AI. Platform Engineering.

Deep-dive articles and video tutorials from our engineers — covering Zabbix, Kubernetes, AI agents, and open-source infrastructure.

Good morning, everyone! Dimitri Bellini here, back on the Quadrata channel – your spot for diving into the exciting world of open source and IT tech. Today, we're tackling a topic some of you have asked about: advanced solutions for interacting with your own documents using AI.

I sometimes wait to showcase software until it's a bit more polished, and today, I'm excited to introduce a particularly interesting one: Ragflow.

Deep Dive into Zabbix Database Monitoring with ODBC

By Dimitri Bellini • Insights
Good morning everyone, and welcome back to my channel, Quadrata! I'm Dimitri Bellini, and this week, we're diving deep into Zabbix again. Why? Because many of you in our fantastic Zabbix Italia Telegram channel asked for a closer look at database monitoring with Zabbix.

Zabbix offers a few ways to monitor databases – using Zabbix Agent 2, User Parameters, and ODBC. While Agent 2 is great for standard metrics and User Parameters offer script-based flexibility (which I personally enjoy!), today we're focusing on what I consider the most elegant and powerful method for many scenarios: **ODBC (Open Database Connectivity)**.
Good morning everyone! Dimitri Bellini here, back with you on Quadrata, my channel dedicated to the fascinating world of open source and IT. You might notice a new backdrop today – still working on the aesthetics, but the content is what matters!

Today, we're shifting gears slightly from our usual Zabbix discussions to explore another critical area in the open-source landscape: firewall solutions. I'm not just talking about the basic firewall tools within a Linux distro, but dedicated distributions that create powerful network appliances.

Good morning everyone! Dimitri Bellini here, back on Quadrata, my channel where we dive into the fascinating world of open source and IT. As I always say, I hope you find these topics as exciting as I do!

This week, we're venturing back into the realm of artificial intelligence, but with a twist. We'll be looking at an incredibly interesting, user-friendly, and – you guessed it – open-source tool called N8n (pronounced "N-eight-N"). While we've explored similar solutions before, N8n stands out with its vibrant community and powerful capabilities, especially its recent AI enhancements.

Good morning everyone, Dimitri Bellini here from Quadrata! While my channel often dives deep into the world of Zabbix and open-source monitoring, today I want to shift gears slightly. I've realized that some foundational concepts, while powerful, aren't always common knowledge, and sharing them can be incredibly helpful.

This week, we're exploring Nginx Proxy Manager. It's not a revolutionary concept in itself, but it's a tool that significantly simplifies managing access to your web services, especially when dealing with HTTPS and multiple applications behind a single IP address.
