Hello everyone, I am having a little problem with the logger. I thought I could print out "logger.debug" values by updating the project side logging file (conf/base/logging.yml) console handler level to "DEBUG" but it doesn't seem to change anything? I'm trying to output logs from pipeline nodes.

handlers:
    console:
        class: logging.StreamHandler
        level: DEBUG
        formatter: simple
        stream: <ext://sys.stdout>

import logging
logger = logging.getLogger(__name__)

def example_node(input):
   logger.debug(input)
   output = input + 1
   return output

I might be just doing something simple wrong but any help be appreciated! It works for info, so just using that for now but would be good to have the option of debug! 🙂

Hello @Lawrence Shaban, what do you have under the

loggers

section of your logging.yml file? Chances are that you need to change the

level

there.

Hey @Antony Milne, thanks for the response! Do you know which level it is I need to change within logging.yml? I've tried a few... I assumed the console handler (which I put in the original post) seemed most logical but it didn't seem to work?

There is a difference between the

handlers

section (the thing you posted above which includes

console

) and the

loggers

section further down the file. Just changing the level of a

handler

won’t show the messages unless the

logger

itself has the level set appropriately. See https://docs.python.org/3/howto/logging.html#logging-flow - the message doesn’t even reach the handler if the logger stops it first 🙂
