Loki
Grafana Loki is a highly scalable, cost-effective log aggregation system that indexes log metadata for fast queries and reduced storage.
Description
Grafana Loki is a horizontally scalable, highly available, and multi-tenant log aggregation system. Inspired by Prometheus, Loki is designed for cost-effectiveness and ease of operation. Unlike other systems, Loki indexes only the metadata of log streams, not the log content itself, leading to significant storage savings and faster query times. It seamlessly integrates with Grafana, Prometheus, and Kubernetes, offering a unified view of metrics, logs, and traces. Loki supports various log formats and sources and provides a powerful query language (LogQL) for efficient log exploration and analysis. It's available as a fully managed service (Grafana Cloud Logs) or as self-managed open-source software.
