About Grafana Loki
Grafana Loki is a log aggregation system designed as the log oriented counterpart to Prometheus. It operates within the cloud native observability ecosystem, specifically targeting Kubernetes and containerized environments. Loki avoids expensive full text indexing by indexing only metadata labels attached to log streams, storing the raw log content in compressed form. This design choice makes Loki significantly simpler to operate and more cost effective than traditional log systems that index every word.
