This approach is outdated because Raw() takes care of DBG_DATA. The best
general approach today is to use an appropriate non-DATA level for
debugs() while using Raw() for printing data inside those debugs():

  debugs(11, DBG_IMPORTANT, "always printed" << Raw(may be printed...));

By default, small strings are always printed while large strings are
only printed if DBG_DATA debugging level is enabled. The behavior can be
tuned by calling .minLevel() on the Raw object.


For example, given "large" input,

  debugs(89, 5, "successfully parsed" << Raw("pfctl input", ...));

will produce something like

  ... successfully parsed pfctl input

with ALL,5 but something like

  ... successfully parsed pfctl input[150]=large-input-here

with ALL,9.


HTH,
