Overview

Grafana Loki is an open-source log aggregation system designed to be cost-effective and easy to operate. It does not index the contents of the logs, but rather a set of labels for each log stream. This approach makes it very efficient for storage and querying, especially when used alongside Prometheus for metrics and Grafana for visualization.

✨ Key Features

  • Cost-effective Log Storage
  • Label-based Indexing
  • Multi-tenancy
  • LogQL Query Language
  • Native integration with Grafana and Prometheus
  • Horizontally Scalable

🎯 Key Differentiators

  • Minimal indexing for cost efficiency
  • Deep integration with the Grafana and Prometheus ecosystem
  • Simple, horizontally scalable architecture

Unique Value: Provides a cost-effective, scalable logging solution that integrates seamlessly with Prometheus and Grafana for a unified metrics and logs experience.
