 * No clear way to introduce HTML-formatted messages (or an HTML formatting option)
 * Not fast enough to do pervasive logging in libraries (we've encountered this with Paste/Pylons, where we'd like to put lots of logging in that people could turn on, but it becomes a notable performance hit).

This page should cover pros and cons of current stdlib logging package.

Pros

  • Almost every feature you could want from logging package is there

Cons

  • Docs are not complete
  • Config files are a little bit hard to comprehend
    • An alternate configuration mechanism is provided by the ZConfig package (PyPI). (Note ZConfig is not a small package to pull in.)

  • API uses camelCase (goes against PEP8 recommendation and most of the stdlib)
  • Rather slow considering the large number of function calls performed internally to check which handler to use
  • Doesn't have runtime scoping (i.e., log messages handled based on the call stack)
  • Difficult to extend log records
  • Difficult to add general context to log messages (e.g., add the request URL to all logging messages during the request)
  • By default it does nothing; basicConfig makes it do something but makes it hard to tweak logging.
  • filters are an abstract class instead of callables
  • Thread-local handlers aren't easy to setup
  • Nothing like keywords or tags for doing multi-dimensional categorization or grouping of messages
  • No clear way to introduce HTML-formatted messages (or an HTML formatting option)
  • Not fast enough to do pervasive logging in libraries (we've encountered this with Paste/Pylons, where we'd like to put lots of logging in that people could turn on, but it becomes a notable performance hit).
