When using Loggly with Python, I log with restapi-logging-handler's LogglyHandler. It's easy to configure, uses threads to compelte the logging asynchronously, and just works. There's more thorough documentation on the GitHub site, but basically you can pip install it:
pip install restapi-logging-handler
Then it's just a matter of configuring the handler:
from restapi_logging_handler import LogglyHandler logglyHandler = LogglyHandler( custom_token='loggly-custom-key', app_tags=['tag1', 'tag2', ...], interval=1.0, max_attemps=5 )
Then, attach that handler to your logger and you're good to go.
