Logs files regularly reaching 100GB+ and filling my hard-drive

My system data is regularly expanding to fill my entire hard-drive. The folder that is the largest is the Logs folder, which seems to fill with unneccesary files every other day. I can delete the Logs folder and it frees up the space but a) it is annoying to have to do this every other day and b) i am worried about the long-term strain on my storage that all the data-build up is having.

MacBook Air 15″, 14.6

At 3am (local), the Periodic LaunchCtl jobs are schedules to rotate and trim those System logs to manage their storage utilization. If you shut your Mac down before bed, and then start it up in the morning. those Periodic processes will startup as soon as it boots.

If you do not reboot your Mac for long periods the System log files will just continue to grow…

Another contributing factor to log file growth is System errors that go unresolved over time…
