What Causes High CPU Usage on a Linux Server at the Same Time Each Day?

A daily spike commonly aligns with cron jobs, log rotation, report generation, backup, or traffic patterns.

Checks to make

Correlate timestamps with cron and systemd timers, process accounting, application logs, and traffic. Identify the process before changing limits. Check whether jobs overlap or scan growing directories, then reschedule, optimize, or add capacity based on measured demand.

When to get help
