The loki_exporter is a Prometheus exporter for Loki. Loki is a horizontally-scalable, highly-available, multi-tenant log aggregation system from the creators of Grafana. The loki_exporter runs queries against the Loki API and returns the number of entries for each stream. This exporter is designed to detect critical log events, where the results can be used to create alerts in Prometheus.
The loki_exporter is also available at Docker Hub:
docker pull ricoberger/loki_exporter
