Subject RE: redefining existing levels?
Date Tue, 25 Aug 2015 23:37:17 GMT
No.  Redefining existing levels is to help ensure we have "24x7" logging always on.  So even
if someone sets the level to "OFF" we still get INFO and above.  Basically we'll have levels
higher (or lower based on what platform we're talking about) than INFO OFF by default and
only turn them on when needed.
 
Thanks,
Nick
