 Telegraf will save in the `telegraf` database from the embedded influxdb server.
 
 
 ## Grafana
 
-You'll have to add yourself the influxdb data source in grafana, using the
-parameters published by the slapos instance.
+A default user is created, username and password are published as connection
+parameters. You can add more users in grafana interface.
 
-http://docs.grafana.org/features/datasources/influxdb/

-When adding datasource, use *proxy* option, otherwise Grafana makes your
-browser query influxdb directly, which also uses a self signed certificate.
-One workaround is to configure your browser to also accept influxdb certificate
-before using grafana, but using proxy seems easier.
+Datasources should be automatically added.

+# Ingesting/Visualizing logs

+Eventhough main feature is visualizing metrics, Grafana has a feature called "Explore" to view logs for a time frame.
+The following backend can be used:

+## Loki

+See `TestLoki` in test for an example.

+## Influxdb

+Influxdb logs only have tags and there does not seem to be a way to search (except than tag and time frame).
