log
{
  ; default_level specifies the logging level for modules
  ; that are not explicitly named. All debugging levels
  ; listed above the selected value are enabled.
  ;
  ; Valid values:
  ;
  ;  NONE ; no messages
  ;  ERROR ; error messages
  ;  WARN ; warning messages
  ;  INFO ; informational messages (default)
  ;  DEBUG ; debugging messages
  ;  TRACE ; trace messages (most verbose)
  ;  ALL ; all messages

  ; default_level INFO

  ; You may override default_level by assigning a logging level
  ; to the desired module name. Module names can be found in two ways:
  ;
  ; Run:
  ;   nfd --modules
  ;
  ; Or look for NFD_LOG_INIT(<module name>) statements in source files.
  ; Note that the "nfd." prefix can be omitted.
  ;
  ; Example module-level settings:
  ;
  ; FibManager DEBUG
  ; Forwarder INFO
