Python logging handler which posts to slack

Project description

Slack logger

This package provides a logging.Handler that will send message to a slack channel. Supports updated slack.WebClient API released in 2019.

Authorization

See https:://api.slack.com to for information on setting up app and get an authorization token. Only a "bot" token is required to use SlackHandler, however, the unittest is more comlete with a "user" token.

Limitations

How often messages can be sent is limited by slack. See https://api.slack.com/docs/rate-limits. By default, this handler only sends accumulated messages every 60 seconds. That can be adjusted by the optional update argument to SlackHandler.

Example

token = 'your token here'
channel = 'your channel name'
handler = SlackHandler(token, channel)
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
handler.setFormatter(formatter)
example_logger = logging.getLogger("Test Logger")
example_logger.propagate = False
example_logger.addHandler(handler)
example_logger.setLevel(logging.INFO)
example_logger.info("Then shalt thou use Python three, no more, no less.")
...
# at end of program
handler.send_remaining()
