I was monitoring my crontab log and I saw this:
Jun 12 20:17:01 HP250G3 CRON[4798]: (root) CMD ( cd / && run-parts --report /etc/cron.hourly) Is this normal? I've never set up any cron job for root.
Thank you for any help!

Yes, it's normal.
From man run-parts
NAME run-parts - run scripts or programs in a directory In your case, run-parts run all scripts in the folder /etc/cron.hourly
My /etc/cron.hourly is empty therefore /etc/cron.daily
