Definition

Grafana Loki is a horizontally scalable, highly available log aggregation system inspired by Prometheus. It is designed to store and query logs from various sources, providing a cost-effective and efficient way to manage log data. Unlike traditional log management systems, Loki does not index the content of the logs but instead indexes metadata, making it more efficient for certain use cases.
