main.py running on App Engine I import
logging and grab a logger (since it’s named,
options_log, I’m not using root logger):
import logging log = logging.getLogger('options_log') log.setLevel(logging.INFO) ... log.info('Hello Log!')
I can’t find any information on where to view my application logs in the Developer Console. I see only
request_log contains logging from
main.py, but how do I log to application log and not
You don’t need to set the logger options, just importing the
logging module and invoking its functions should suffice, just like the in examples on the page you referenced:
import logging import webapp2 class MainPage(webapp2.RequestHandler): def get(self): logging.debug('This is a debug message') logging.info('This is an info message')
You should also note that the application logs can not be seen independently, they are always attached to the request log for the request in response to which they were produced. From the doc you referenced:
Each request log contains a list of application logs (AppLog)
associated with that request, returned in the
property. Each app log contains the time the log was written, the log
message, and the log level.
Note: A request log can only hold 1000 app logs. If you add more than 1000, the older logs will not be retained.
You need to click on the left-most caret to expand the request log entry to display the respective app log(s):
If after expanding the request log you still don’t see your app logs I suspect that your attempt to set options on a specific logger – the
'options_log' one – might be your problem. If you still want to set options, try doing it for the default logger (root logger?) instead of specifying one. Or drop the options altogether.
