Here we collect the guidelines and tricks to leverage debugging and logging Mapnik when developing in **the upcoming 2.1.0 release**.
Mapnik >= 2.1.x supports a variety of logging options to make it possible for the developer or user to see what Mapnik is doing under the hood.
The amount of possible logging functionality is determined at compile time, but the logging verbosity can also be controlled at runtime.
## Compile time options
When you configure Mapnik you have several options that can be set during the configure stage of building which impact how logging behaves
- DEFAULT_LOG_SEVERITY - Default `error`. Other named severity levels are: `['debug', `warn`, `none`.
- ENABLE_LOG - Default `False`. If set to `True` then logging of all severity types will be enabled. This is `True` by default if `DEBUG=True` (see option below).
- ENABLE_STATS -
- DEBUG
