Loki is a horizontally-scalable, highly-available, multi-tenant log aggregation system inspired by Prometheus. Loki differs from Prometheus by focusing on logs instead of metrics, and collecting logs via push, instead of pull. Loki is designed to be very cost effective and highly scalable. Unlike other logging systems, Loki does not index the contents of the logs, but only indexes metadata about your logs as a set of labels for each log stream. By utilizing the power of LogQL (Grafana Loki’s PromQL-inspired query language) over the collected Nginx logs we can create advanced visualizations of internal works of the application.
