Grafana

From the Grafana GitHub

The open and composable observability and data visualization platform. Visualize metrics, logs, and traces from multiple sources like Prometheus, Loki, Elasticsearch, InfluxDB, Postgres and many more.

Initial credentials

After the first start of Grafana, you can login using the following credentials:

  • Username: admin
  • Password: admin

Update support

The egg should keep the data and conf folder when reinstalling. Therefore a reinstallation with "latest" as the selected version can be used to update Grafana.

If you want to reset the server completly, remove the conf and data directories manually before reinstalling.
