Grafana Loki

Grafana Loki is an open-source log management platform that is available when using the Developer Quickstart.

The Promtail configuration ingests logs at regular defined intervals and outputs them to Loki for storage.

The pipeline configuration in Promtail defines pipeline stages that can collate logs natively or using the JSON format.


If using the pipeline regex stage in Promtail, configuration must match your log format.

To view the GoQuorum Quickstart network logs in Loki:

  1. Start the Developer Quickstart with Besu, selecting Loki monitoring.

  2. Open the Grafana Loki address listed by the sample networks script.

    The logs display in Loki.
