# Grafama ### From the [Grafana](https://github.com/grafana/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. ### Server Ports Ports required to run the server in a table format. | Port | default | | ------------ | ------- | | Webinterface | 3000 |
