Good morning everyone! Dimitri Bellini here, and welcome back to Quadrata, my channel dedicated to the world of open source and all the IT that I, and hopefully you, find fascinating.

This week, we're diving into a powerful solution that addresses a common and persistent challenge in IT management: the lack of a single, reliable source of information. In large infrastructures, it's often difficult to know what objects exist, where they are, what their relationships are, and how to even begin monitoring them. Many turn to a Configuration Management Database (CMDB), but keeping it manually updated is a struggle. What if we could automate this process?

Good morning everyone, Dimitri Bellini here! It’s great to be back with you on Quadrata, my channel dedicated to the world of open source and IT. It’s been a little while since my last video, as I’ve been quite busy traveling between the Zabbix Summit in Riga and Gitex in Dubai. The energy at the Summit was incredible, and I returned not just with great memories but with a clear vision of the future of monitoring. And today, I want to share that vision with you.

So, grab a coffee, and let’s dive into a recap of the fantastic Zabbix Summit and, more importantly, the groundbreaking features coming in the next major release: Zabbix 8.0 LTS.

Good morning and welcome, everyone! It's Dimitri Bellini, back again on Quadrata, my channel dedicated to the open-source world and the IT that I love. It’s been a little while since we talked about our good friend Zabbix, and I’m excited to share something I stumbled upon that I think you're going to love.

While browsing the Zabbix support portal, I came across a community member, Ryan Eberle, who has developed an incredible set of custom widgets. His GitHub repository is a goldmine of enhancements that bring a whole new level of functionality and clarity to our Zabbix dashboards. These aren't just minor tweaks; they are game-changing improvements that address many of the limitations we've all faced.

Good morning, everyone! It’s Dimitri Bellini, and welcome back to Quadrata, my channel dedicated to the world of open-source IT. It’s an exciting week because our good friend, Zabbix, has just rolled out a major new version: Zabbix 7.4! After months of hard work from the Zabbix team, this release is packed with features that will change the way we monitor our infrastructure. So, let's dive in together and explore what’s new.

Let's start with what I consider the most mind-bending, "centrifugal" new feature: nested low-level discovery (LLD). Until now, LLD was fantastic for discovering objects like file systems or network interfaces on a host. But we couldn't go deeper. If you discovered a database, you couldn’t then run another discovery *within* that database to find all its tablespaces dynamically.

Good morning, everyone! It’s Dimitri Bellini, and welcome back to Quadrata, my channel dedicated to the world of open source. A few weeks ago, I had one of those heart-stopping moments we all dread: a chunk of my data suddenly became inaccessible. While I had some backup systems in place, they weren't as reliable as I thought. That scare sent me on a mission to find the best, most robust open-source backup solution out there.

We often don't think about backups until it's too late. Whether it's a broken hard drive, corrupted files, or the dreaded ransomware attack, having a solid backup strategy is the only thing that stands between you and disaster. But remember, as the saying goes, "The backup is guaranteed, but the restore is another story." A good tool needs to handle both flawlessly.
