I am having the same issues that Baron reported. What can I do about it? From a small search I saw that there is data from October until December 2018, but not for the last 90 days, and not for raw-logs, which I also used as a replacement for apachelogs*, since an index for that was not an option.
Thank you for your help and your time.
I am having a similar issue to what has been reported. After creating an index pattern for user_message index, no fields or documents are loaded in the index pattern, user_messages index pattern has no data. I am unable to do the tasks in the practice exam.
