What problem does it solve?
Grafana Loki addresses the challenge of scalable, cost-effective log aggregation by indexing metadata and storing compressed log chunks in object storage, enabling fast search and multi-tenant isolation across large clusters.
Core Features & Use Cases
- Horizontal scalability with the Distributor, Ingester, Querier, Query Frontend, and Compactor
- Label-based log organization and multi-tenant isolation using LogQL
- Flexible storage backends (S3, Azure Blob, GCS) with schema options (TSDB)
- Kubernetes-friendly deployment via Helm in modes such as Monolithic, Simple Scalable, and Distributed
- Native OpenTelemetry/OTLP integration for seamless log ingestion
- Operational guidance for retention, compaction, and index management
Quick Start
Install Loki with a scalable deployment using Helm, configure a compatible object store, deploy a log collector (Promtail) or enable OTLP ingestion, then access Grafana dashboards and run sample LogQL queries against Loki.
