log_logger_XXX = comma separated list of regexps
Logger levels can be explicitly specified for specific loggers as
opposed to a global logging level. Specific loggers are indiciated
by a list of regular expressions bound to a level. If a logger's
name matches the regexp then it is assigned that level. The keys
in the Env config must begin with "log_logger_level_" and then be
followed by a symbolic or numeric log level, for example:
log_logger_level_debug = ipalib\.dn\..*
log_logger_level_35 = ipalib\.plugins\.dogtag
The first line says any logger belonging to the ipalib.dn module
will have it's level configured to debug.
The second line say the ipa.plugins.dogtag logger will be
configured to level 35.
Note: logger names are a dot ('.') separated list forming a path
in the logger tree. The dot character is also a regular
expression metacharacter (matches any character) therefore you
will usually need to escape the dot in the logger names by
preceeding it with a backslash.
