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.

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.
