Where do print statements from Django app go?

Instead of using print statements you can use python's logging module. http://docs.python.org/howto/logging.html

Print goes to sys.stdout, which is thrown away by mod_wsgi. You have to print to sys.stderr,

import sys
print >> sys.stderr, "string or object goes here"

This will send the output to the error log defined in httpd.conf. There are solutions that send sys.stdout to sys.stderr but they have unexpected side effects, the safest way is the above method.
