Advanced Configuration Files
The oslo.config options described in /opts make it easy to enable some default logging
configuration behavior such as setting the default log level and output
file. For more advanced configurations using translations or multiple
output destinations oslo.log relies on the Python standard library
logging module configuration file features.
The configuration file can be used to tie together the loggers, handlers, and formatters and provide all of the necessary configuration values to enable any desired behavior. Refer to the Python logging Module Tutorial for descriptions of these concepts.
Logger Names
Loggers are configured by name. Most OpenStack applications use
logger names based on the source file where the message is coming from.
A file named myapp/package/module.py corresponds to a
logger named myapp.package.module.
Loggers are configured in a tree structure, and the names reflect
their location in this hierarchy. It is not necessary to configure every
logger, since messages are passed up the tree during processing. To
control the logging for myapp, for example, it is only
necessary to set up a logger for myapp and not
myapp.package.module.
The base of the tree, through which all log message may pass unless
otherwise discarded, is called the root logger.
