Loki + Grafana: A Lightweight and Cost-Effective Logging Solution for the Cloud

We’re wrapping up our series on centralized logging with a modern and innovative solution: Loki together with Grafana. Developed by Grafana Labs, this stack reimagines how logging works — making it simple, efficient, and especially appealing for those already using Prometheus.

What Is Loki and How Does It Work?

Loki is a log aggregation system designed to minimize resource usage. It indexes only metadata (labels), while the log messages themselves are stored in compressed form — following the same philosophy as Prometheus, but for logs.

Why Do We Need Centralized Logging? Making Sense of Log Chaos

We’ve already discussed the importance of metrics monitoring for understanding the health of your IT infrastructure. But metrics are only part of the picture. To truly understand what’s happening inside your systems and applications, you need logs.

Logs are records of events generated by operating systems, applications, network devices, and nearly any software component. They capture what, when, where, and why something happened. Think of them as the “black box” of your infrastructure — an invaluable source of information for debugging, auditing, and incident investigation.
