Grafana Loki
Like Prometheus, but for logs.
Overview
Grafana Loki is an open-source log aggregation system designed to be 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. This approach makes it very efficient for storage and querying, especially when used alongside Prometheus for metrics and Grafana for visualization.
