  # 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:
  #analytics:
  #  reporting_enabled: false
