The HDX Python Utilities Library provides a range of helpful utilities:

1. Easy downloading of files with support for authentication, streaming and hashing

2. Simple emailing

3. Easy logging setup

4. Dictionary and list utilities

• Configuring Logging

Usage

The library has detailed API documentation which can be found here: http://ocha-dap.github.io/hdx-python-utilities/. The code for the library is here: https://github.com/ocha-dap/hdx-python-utilities.

Configuring Logging

The library provides coloured logs with a simple default setup. If you wish to change the logging configuration from the defaults, you will need to call setup_logging with arguments.

from hdx.utilities.easy_logging import setup_logging
...
logger = logging.getLogger(__name__)
setup_logging(KEYWORD ARGUMENTS)

KEYWORD ARGUMENTS can be:

Choose	Argument	Type	Value	Default
One of:	logging_config_dict	dict	Logging configuration dictionary
or	logging_config_json	str	Path to JSON Logging configuration
or	logging_config_yaml	str	Path to YAML Logging configuration	Library’s internal logging_configuration.yml
One of:	smtp_config_dict	dict	Email Logging configuration dictionary
or	smtp_config_json	str	Path to JSON Email Logging configuration
or	smtp_config_yaml	str	Path to YAML Email Logging configuration

Do not supply smtp_config_dict, smtp_config_json or smtp_config_yaml unless you are using the default logging configuration!

If you are using the default logging configuration, you have the option to have a default SMTP handler that sends an email in the event of a CRITICAL error by supplying either smtp_config_dict, smtp_config_json or smtp_config_yaml. Here is a template of a YAML file that can be passed as the smtp_config_yaml parameter:

handlers:
    error_mail_handler:
        toaddrs: EMAIL_ADDRESSES
        subject: "RUN FAILED: MY_PROJECT_NAME"

Unless you override it, the mail server mailhost for the default SMTP handler is localhost and the from address fromaddr is noreply@localhost.

To use logging in your files, simply add the line below to the top of each Python file:

logger = logging.getLogger(__name__)

Then use the logger like this:

logger.debug('DEBUG message')
logger.info('INFORMATION message')
logger.warning('WARNING message')
logger.error('ERROR message')
logger.critical('CRITICAL error message')
