In a business world increasingly oriented towards efficiency and mobility, network management becomes a critical factor for success. Cisco Meraki stands as an undisputed leader thanks to its ability to offer a fully cloud-based technology, allowing companies of any size to manage their network devices remotely and centrally.

We recently published the IT Topic “IT System Monitoring: advanced solutions for total visibility and security”, in which we present how advanced solutions for IT system monitoring optimize performance, improve security and reduce alert noise with AI and machine learning. We also mentioned that there are four golden signals that IT systems monitoring should focus on.

Learn the differences between SLA, SLO and SLI and how to implement these metrics to improve the quality of service offered by your company. Also, learn about the challenges and best practices for implementing them, along with some real-world examples.

Resilience in today’s liquid business environment demands flexibility. The term “observability” replaces monitoring, reflecting the need to adapt and be agile in the face of challenges. The key is to dissolve operations into the cloud, integrating tools and operational expertise for effective resilience. I remember that when I started my professional career (in a bank) one of the first tasks I was handled was to secure an email server exposed to the internet.

You drink tap water every day, right? Do you know who invented the filtering mechanism that makes water pure and clean?… Well, do you actually care? Do you know that this mechanism is exactly the same in all the taps of all the houses of any country? Do you know that this specialized piece is the work of an engineer who does it just because? Can you imagine what could happen if this person had a bad day?

Talking about too many cybersecurity alerts is not talking about the story of Peter and the Wolf and how people end up ignoring false warnings, but about its great impact on security strategies and, above all, on the stress it causes to IT teams, which we know are increasingly reduced and must fulfill multiple tasks in their day to day.

Today, many companies generate and store huge amounts of data. To give you an idea, decades ago, the size of the Internet was measured in Terabytes (TB) and now it is measured in Zettabytes (ZB). Relational databases were designed to meet the storage and information management needs of the time. Today we have a new scenario where social networks, IoT devices and Edge Computing generate millions of unstructured and highly variable data.

Today, digital trust is required inside and outside the organization, so tools must be implemented, with cybersecurity methods and best practices in each layer of your systems and their infrastructure: applications, operating systems, users, both on-premise and in the cloud. This is what we call System Hardening an essential practice that lays the foundation for a safe IT infrastructure.

From the computer, we increasingly perform different tasks simultaneously (listening to music while writing a report, receiving files by email and downloading videos), which involve executing commands, and sending and receiving data. Over time, computer performance can suffer if CPU usage is not optimized. But what is a CPU?

Collectd is a daemon (i.e. running in the background on computers and devices) that periodically collects metrics from different sources such as operating systems, applications, log files, and external devices, providing mechanisms to store values in different ways (e.g. RRD files) or makes it available over the network. With this data and its statistics you may monitor systems, find performance bottlenecks (by performance analysis) and predict system load (capacity planning).
