Can't find Google AppEngine logs to stdout

Question

My python application on the Google App Engine (standard environment) writes some logs to stdout. I used to be able to see them on the Logs Viewer but not anymore. The default options under the "Log name" drop down menu do not show stdout, and I have tried to manually add logName="projects/airlib-main/logs/stdout" into the Query Builder but it doesn't find anything.

I solved my problem by NOT using basicConfig to configure the logs and rather instantiate my own loggers and use them throughout the application. The python documentation says that < This function does nothing if the root logger already has handlers configured > and maybe the Google App Engine does that now. My application used to produce logs properly so there might have been a change recently in the way the Google App Engine works in this environment.

I would recommend you to take a look at the post from the Community: How to group related request log entries GAE python 3.7 standard env. This post provides you with possible solutions to your stdout logging.

For example, as mentioned on this answer here - that it's in Python language - there are some methods that you can use to set the stdout as the pattern for logs. So, checking this post should assist you in configuring the use of stdout on your App Engine.
