052 | Prometheus + Node Exporter + Grafana: The De Facto Standard for Cloud Environments

July 14, 2025

We’ve reviewed Munin as a simple solution for basic monitoring. Now let’s move on to a stack that has become an indispensable tool in the world of modern cloud infrastructure, microservices, and containers: Prometheus, Node Exporter, and Grafana. This trio provides a powerful, flexible, and scalable approach to collecting, storing, analyzing, and visualizing metrics.

What is Prometheus and Its Ecosystem?

Prometheus is an open-source monitoring system originally developed at Google and later handed over to the Cloud Native Computing Foundation (CNCF). Its key feature is the “pull” model: Prometheus scrapes metrics from targets via HTTP endpoints.

050 | Why Do We Need Monitoring? Guarding the Stability of Your IT

July 12, 2025

In today’s world, where digital technologies penetrate every sphere of life, the stable operation of IT infrastructure is not just a desirable condition — it is a critical necessity. Whether it’s a small website, a large online store, a mobile application, or an internal corporate system — any failure can lead to serious losses, reputational damage, and user dissatisfaction. This is where monitoring steps in.

What is Monitoring and Why Is It Important?

Monitoring in IT is the continuous collection, analysis, and visualization of data about the state and performance of infrastructure, applications, and services. Imagine you have a complex machine, like a car. To keep it running smoothly, you regularly check fuel level, oil, tire pressure. Monitoring serves the same purpose for servers, databases, networks, and applications.
