Use custom logging

The Splunk Machine Learning Toolkit (MLTK) ships with utilities to make logging easy to manage.

Note: MLTK relies on a different Python interpreter than the interpreter that ships with Splunk Enterprise.

To begin, import a logger. For more detailed logging, you can use a logger with a custom name as shown in the following example: 

from cexc import get_logger

logger = get_logger('MyCustomLogging')
logger.warn('warning!')
logger.error('error!')
logger.debug('info!')

Logger messages are logged to $SPLUNK_HOME/var/log/mlspl.log.

Along with the name provided in get_logger, the function is also recorded: 

1491862833.627798 2017-04-10 15:20:33,627 WARNING [mlspl.MyCustomLogging] [__init__] warning!
1491862833.627949 2017-04-10 15:20:33,627 ERROR [mlspl.MyCustomLogging] [__init__] error!
1491862833.628024 2017-04-10 15:20:33,628 DEBUG [mlspl.MyCustomLogging] [__init__] info!

Note: If you cannot find messages using the logger, you can also look in the search.log.
