Google Cloud Functions Python Logging issue

Question

I\'m not sure how to say this but, I\'m feeling like there is something under the hood that was changed by Google without me knowing about it. I used to get my logs from my

Stackdriver Logging severity filters are no longer supported when using the Python native logging module.

However, you can still create logs with certain severity by using the Stackdriver Logging Client Libraries. Check this documentation in reference to the Python libraries, and this one for some usage-case examples.

Notice that in order to let the logs be under the correct resource, you will have to manually configure them, see this list for the supported resource types. As well, each resource type has some required labels that need to be present in the log structure.

As an example, the following code will write a log to the Cloud Function resource, in Stackdriver Logging, with an ERROR severity:

from google.cloud import logging
from google.cloud.logging.resource import Resource

log_client = logging.Client()

# This is the resource type of the log
log_name = 'cloudfunctions.googleapis.com%2Fcloud-functions' 

# Inside the resource, nest the required labels specific to the resource type
res = Resource(type="cloud_function", 
               labels={
                   "function_name": "YOUR-CLOUD-FUNCTION-NAME", 
                   "region": "YOUR-FUNCTION-LOCATION"
               },
              )
logger = log_client.logger(log_name.format("YOUR-PROJECT-ID"))
logger.log_struct(
 {"message": "message string to log"}, resource=res, severity='ERROR')

return 'Wrote logs to {}.'.format(logger.name) # Return cloud function response

Notice that the strings in YOUR-CLOUD-FUNCTION-NAME, YOUR-FUNCTION-LOCATION and YOUR-PROJECT-ID, need to be specific to your project/resource.
