Grafana: Grafana is a multi-platform open source analytics and interactive visualisation web application. It provides charts, graphs, and alerts for the web when connected to supported data sources.
Loki: Loki is a horizontally scalable, highly available, multi-tenant log aggregation system inspired by Prometheus. It is designed to be very cost effective and easy to operate. It does not index the contents of the logs, but rather a set of labels for each log stream.
