Logging Levels
|

--------------
|

|
||||
The numeric values of logging levels are given in the following table. These are
|
||||
primarily of interest if you want to define your own levels, and need them to
|
||||
have specific values relative to the predefined levels. If you define a level
|
||||
with the same numeric value, it overwrites the predefined value; the predefined
|
||||
name is lost.
