July 16, 2025

In our series on monitoring systems, we’ve reviewed Munin, Prometheus with Grafana, and Zabbix. Now it’s time to talk about a solution that addresses one of the main pain points of Prometheus users — long-term, scalable, and efficient time-series storage. Meet VictoriaMetrics, a high-performance and cost-effective TSDB (time-series database) that perfectly complements the Prometheus ecosystem when paired with Grafana for visualization.

What Is VictoriaMetrics and Why Do You Need It?

Prometheus handles real-time monitoring and storage well, but its built-in TSDB isn’t designed for long-term retention or scaling to terabytes or petabytes of data. That’s where VictoriaMetrics comes in.

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.
