+#### Optional:Set up logging for splunklib
++ The default level is WARNING, which means that only events of this level and above will be visible
++ To change a logging level we can call setup_logging() method and pass the logging level as an argument.
++ Optional: we can also pass log format and date format string as a method argument to modify default format

+## Optional:Set up logging using logging.conf file
++ Inside the **default** directory of our app, we have a [logging.conf](https://github.com/splunk/splunk-sdk-python/blob/master/examples/searchcommands_app/package/default/logging.conf) file.
++ In logging.conf file we can define loggers, handlers and formatters for our app. refer [this doc](https://docs.python.org/2/library/logging.config.html#configuration-file-format) for more details
++ Logs will be written in the files specified in the handlers defined for the respective loggers
+  + For **'searchcommands_app'** app logs will be written in **searchcommands_app.log** and **splunklib.log** files defined in respective handlers, and are present at $SPLUNK_HOME/etc/apps/searchcommands_app/ dir
+  + By default logs will be written in the app's root directory, but it can be overriden by specifying the absolute path for the logs file in the conf file
++ By default, logging level is set to WARNING
++ To see debug and above level logs, Set level to DEBUG in logging.conf file
