cron is only one of the running daemons that consume CPU cycles and system resources:
$ ps -eo 'tty,pid,comm' | grep ^? | grep cron ? 841 cron ? 896 cron
For a complete list of all 264 on my system I use:
ps -eo 'tty,pid,comm' | grep ^?
So which deamon runs every 30 minutes? The first google hit is the
chef deamon (not a cooking thing): https://stackoverflow.com/questions/14905278/chef-daemon-running-every-30-minutes
If it’s not documented you would have to check every single daemon’s source code to see how often it run.
