Self-hosted Grafana Loki integration for Grafana Cloud

Send self-monitoring metrics and logs from Grafana Loki or GEL running in your Kubernetes cluster to Grafana Cloud. The integration comes with dashboards to help monitor the health of your Loki or GEL cluster as well as understand per-tenant usage and behavior.

This integration includes 4 useful alerts and 10 pre-built dashboards to help monitor and visualize Self-hosted Grafana Loki metrics and logs.

Before you begin

This integration works with the Loki helm chart deployed on Kubernetes.

Install Self-hosted Grafana Loki integration for Grafana Cloud

  1. In your Grafana Cloud stack, click Connections in the left-hand menu.
  2. Find Self-hosted Grafana Loki and click its tile to open the integration.
  3. Review the prerequisites in the Configuration Details tab and set up Grafana Agent to send Self-hosted Grafana Loki metrics and logs to your Grafana Cloud instance.
  4. Click Install to add this integration’s pre-built dashboards and alerts to your Grafana Cloud instance, and you can start monitoring your Self-hosted Grafana Loki setup.
