 # By default, Loki will send anonymous, but uniquely-identifiable usage and configuration
 # analytics to Grafana Labs. These statistics are sent to https://stats.grafana.org/
 #
 # Statistics help us better understand how Loki is used, and they show us performance
 # levels for most users. This helps us prioritize features and documentation.
 # For more information on what's sent, look at
 # https://github.com/grafana/loki/blob/main/pkg/usagestats/stats.go
 # Refer to the buildReport method to see what goes into a report.
 #
 # If you would like to disable reporting, uncomment the following lines:
