Grafana Loki Has a Free Log Aggregation System Like Prometheus But for Logs

Grafana Loki is a horizontally-scalable log aggregation system. Unlike Elasticsearch, it indexes only metadata (labels), not the full text. What You Get for Free No full-text indexing — stores compressed logs cheaply Label-based querying with LogQL Native Grafana integration Multi-tenancy — built-in tenant isolation S3/GCS backend — cheap object storage Query Logs with LogQL {job="nginx"} |= "error" | json | status >= 500 Why Loki Over Elasticsearch? Feature Loki Elasticsearch Storage cost 10-50x cheaper Expensive Setup Minutes Hours Best for Logs + Grafana Full-text search Need observability infrastructure?
