# Statistics setup
# Please don't modify this file as your changes might be overwritten with

# You can modify 'local.d/statistic.conf' to add and merge
# parameters defined inside this section
#
# You can modify 'override.d/statistic.conf' to strictly override all
# parameters defined inside this section

# If you just need to change the default bayes classifier, you can also use
# 'local.d/classifier-bayes.conf' or 'override.d/classifier-bayes.conf'. But
# never ever use both `statistic.conf` and `classifier-bayes.conf` locals files
# together!
