What's this?

A description of Butler's telemetry feature is available here.

Settings in config file

Butler:
  # Logging configuration
  ...
  ...
  anonTelemetry: true     # Can Butler send anonymous data about what computer it is running on?
                          # More info on whata data is collected: https://butler.ptarmiganlabs.com/docs/about/telemetry/
                          # Please consider leaving this at true - it really helps future development of Butler!

Setting anonTelemetry to true enables telemetry, setting it to false disables telemetry.
