How to troubleshoot a DSX scheduled notebook?

I have a DSX notebook that I can run manually usng the DSX user interface and it populates some data in a Cloudant database.

I have scheduled the notebook to run hourly. Overnight I would have expected the job to have run many times, but the Cloudant database has not been updated.

How can I debug the scheduled job? Are there any logs that I can check to verify that the notebook has actually been executed? Is the output from my notebook saved to log files? Where can I find these files?

Solution

  • One possibility is to look into the kernel logs of your notebook kernel. For that you need to use a Python notebook.

    Check the following location on the gpfs in your Python notebook: 

    !ls /gpfs/fs01/user/USERID/logs/notebook/

    To get the USERID execute the following code:

    !whoami

    You should find for each kernel a log file, e.g. kernel-python3-20170105_102510.
