[ckan-dev] Problems installing CKAN, logging

[Adrià Mercader]

Hi Hilde,

If you want to write the log to a file you need to use a different
handler than the console one, either FileHandler or
RotatingFileHandler.

What instructions did you follow for this? They may need clarification.

Here is an example:

[handler_file]
class = logging.handlers.RotatingFileHandler
formatter = generic
level = NOTSET
args = ('/var/log/ckan/default/production.log', 'a', 2000000, 9)


More details here:
