import contek_timbersaw as timbersaw

timbersaw.setup()
logger = logging.getLogger(__name__)

logger.info('foo bar')

2. Results

ERROR level logging will be written to:

{WORKING_DIRECTORY}/logs/error/{yyyy}-{MM}-{dd}.log

3. Features

Compression

When an INFO log file passes its active period (defaults to when a new day starts), it gets GZipped. For example:

2009-01-03.log -> 2009-01-03.log.gz

Retention

Old logs will be deleted after their retention period. By default, INFO logs are kept for 14 days and ERROR logs are kept for 28 days.

5. Customization

Settings are configurable via environment properties. They can be set before your program starts using export. For example:

Otherwise, they can be set at runtime using os.environ. For example:

import os

os.environ['log_error_retention_days'] = '7'
