Logging

BNDL uses the python logging package. To simpify log configuration logging.conf in the current working directory is loaded like so:

logging.config.fileConfig('logging.conf', disable_existing_loggers=False)

This is done by default when the bndl modules is imported (and thus when a worker / driver / shell is started).

An example log configuration that logs to stdout:

[loggers]
keys=root, dataset, scheduler, worker, rmi

[handlers]
keys=console

[formatters]
keys=simple

[logger_root]
level=WARNING
handlers=console

[logger_dataset]
level=INFO
handlers=console
qualname=bndl.compute.dataset
propagate=0

[logger_scheduler]
level=DEBUG
handlers=console
qualname=bndl.execute.scheduler
propagate=0

[logger_worker]
level=DEBUG
handlers=console
qualname=bndl.execute.worker
propagate=0

[logger_rmi]
level=INFO
handlers=console
qualname=bndl.rmi
propagate=0

[handler_console]
class=StreamHandler
level=DEBUG
formatter=simple
args=(sys.stdout,)

[formatter_simple]
format= %(asctime)s - %(name)s - %(levelname)8s - %(message)s
datefmt=
