I'm doing a small research on IPython kernel and trying to get debug logs out of it and see how it interacts with a notebook. Now it looks like the documentation and example configs shipped in my distribution is totally outdated.
The questions
- Where the ipython kernel log files are located?
- How can I enable DEBUG level logging in both jupyter notebook and ipython kernel?
What I've tried
Please read this section before giving links to the official docs
First I created profiles for both IPython and notebook with the following commands:
$ ipython profile create
$ jupyter notebook --generate-config
As expected three files where created:
- .jupyter/jupyter_notebook_config.py
- .ipython/profile_default/ipython_config.py
- .ipython/profile_default/ipython_kernel_config.py
In these files I found similar commented fragments:
# Set the log level by value or name.
# c.Application.log_level = 0
I tried to uncomment it in the jupyter config. Instead of adding more details it totally disabled console output for the jupyter process. I also tried value 50 it has the same result, value DEBUG gave me Python error on start.
I also played with these values in ipython's configs but I wasn't able to find log files location.
In mail list command line option --log-level=DEBUG is mentioned and indeed it works for jupyter. But I really want to persist this setting in a profile and have debug info for the kernel too.
Config options NotebookApp.log_level and IPKernelApp.log_level also change nothing.
