# Looks up configurations in SCOUT_* namespace, in the same manner as the Ruby agent does.

# For any given key ("monitor" for instance), it is uppercased, and prepended

# with "SCOUT_" and then looked up in the environment.

#

# If you wish to define your own environment variables to use, instead of these

# defaults, the Application config {:system, "MY_SCOUT_KEY_VAR"} approach allows

# that
