Structured Logging for Python#
Release v22.1.0.dev0 (What's new?)
structlog makes logging in Python faster, less painful, and more powerful by adding structure to your log entries.
It has been successfully used in production at every scale since 2013, while embracing cutting-edge technologies like asyncio or type hints along the way, and influenced the design of structured logging packages in other ecosystems.
Thanks to its highly flexible design, it’s up to you whether you want
structlog to take care about the output of your log entries or whether you prefer to forward them to an existing logging system like the standard library’s
If you’re not sure whether
structlogis for you, have a look at Why….
If you can’t wait to log your first entry, start at Getting Started and then work yourself through the basic docs.
Once you have basic grasp of how
structlogworks, acquaint yourself with the integrations
structlogis shipping with.
Integration with Existing Systems#
structlog can be used immediately with any existing logger, or with the one with that it ships.
However it comes with special wrappers for the Python standard library and Twisted that are optimized for their respective underlying loggers and contain less magic.
