  ## Plugin Log Level
  -TBD
  \ No newline at end of file
  +The defult plugin log level is the same as the overall Core logging level.
  +
  +It can be changed, however, by assinging a value to ``NWNX_<x>_LOG_LEVEL`` (where <x> is the plugin name in all caps) in the same manner as the Core logging level.
  +See the Core documentation for a description of available logging levels.
  +
  +__Example__
  +```
  +# Set the sql plugin to warning and above (warning, error, and fatal only)
  +export NWNX_SQL_LOG_LEVEL=4
  +```
