Grafana Loki Skill

Comprehensive guide for Grafana Loki - the cost-effective, horizontally-scalable log aggregation system inspired by Prometheus.

What is Loki?

Loki is a horizontally-scalable, highly-available, multi-tenant log aggregation system that:

• Indexes only metadata (labels) - Not full log content like traditional systems
• Stores compressed chunks in affordable object storage (S3, GCS, Azure Blob)
• Uses Prometheus-style labels for organizing log streams
• Multi-tenant by default with built-in tenant isolation
• Cost-efficient - Dramatically smaller index and lower operational costs
