New in version 2.0.0.

Logging may be enabled programmatically via couchbase_core.enable_logging() or via the environment, setting the LCB_LOGLEVEL environment variable to a value between 0 and 5.

“Programmatic” logging uses Python’s standard logging module. If you are not familiar with Python’s logging module, see https://docs.python.org/2/howto/logging.html#logging-basic-tutorial for a basic tutorial (note, the logging module is also available on Python 3)

Note the environment variable method is actually a variable interpreted by the underlying C library (libcouchbase) and is available on all C library versions starting from 2.4.0.

Note that logging messages themselves are currently limited to output from the C library
