I'm using Logging (
import logging) to log messages.
Within 1 single module, I am logging messages at the debug level
Some of these debug messages come from
function_a() and others from
function_b(); I'd like to be able to enable/disable logging based on whether they come from a or from b;
I'm guessing that I have to use Logging's filtering mechanism.
Can someone show me how the code below would need to be instrumented to do what I want?
import logging logger = logging.getLogger( "module_name" ) def function_a( ... ): logger.debug( "a message" ) def function_b( ... ): logger.debug( "another message" ) if __name__ == "__main__": logging.basicConfig( stream=sys.stderr, level=logging.DEBUG ) #don't want function_a()'s noise -> .... #somehow filter-out function_a's logging function_a() #don't want function_b()'s noise -> .... #somehow filter-out function_b's logging function_b()
If I scaled this simple example to more modules and more funcs per module, I'd be concerned about lots of loggers;
Can I keep it down to 1 logger per module? Note that the log messages are "structured", i.e. if the function(s) logging it are doing some parsing work, they all contain a prefix
logger.debug("parsing: xxx") – can I somehow with a single line just shut-off all "parsing" messages (regardless of the module/function emitting the message?)
